All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The embodiment of the invention provides a topology analysis method, a topology analysis device and a storage medium.

For example, referring to fig. 1, the electronic device may receive an analysis request, determine a target distributed system that needs to perform topology analysis according to the analysis request, where the target distributed system includes a plurality of functional units, perform static analysis on the functional units included in the target distributed system to obtain a static analysis result, identify function modules included in the functional units according to the static analysis result corresponding to the functional units, identify pairs of functional units having a call relationship according to the function modules included in the functional units, and finally generate a call topology corresponding to the target distributed system according to the determined pairs of functional units. And then, when the management requirement of the target distributed system exists, the management can be correspondingly carried out according to the generated calling topology.

The following are detailed below. The order of the following examples is not intended to limit the preferred order of the examples.

The first embodiment,

In the present embodiment, description will be made from the perspective of a topology analysis apparatus, which may be specifically integrated in an electronic device such as a terminal or a server.

The embodiment of the invention provides a topology analysis method, which comprises the following steps: receiving an analysis request, and determining a target distributed system which needs topology analysis according to the received analysis request, wherein the target distributed system comprises a plurality of functional units; performing static analysis on functional units included in the target distributed system to obtain a static analysis result; identifying a function module included in the function unit according to a static analysis result corresponding to the function unit; identifying a functional unit pair with a calling relation according to a function module included in each functional unit; and generating a calling topology corresponding to the target distributed system according to the determined functional unit pair.

As shown in fig. 2a, the specific process of the topology analysis method may be as follows:

in 201, an analysis request is received, and a target distributed system requiring topology analysis is determined according to the analysis request, where the target distributed system includes a plurality of functional units.

Among them, the topology analysis is to analyze the topology of calls of functional units included in the distributed system. It should be noted that the target distributed system is a distributed system that includes a plurality of functional units, each deployed at a different network address. It should be understood by those skilled in the art that the functional units of the target distributed system may be deployed on a plurality of different physical servers, or may be deployed on the same physical server.

In the present invention, the topology analysis device can receive the analysis request in a variety of different ways.

For example, the topology analysis apparatus may provide a topology analysis interface to a technician through an electronic device where the topology analysis apparatus is located, where the topology analysis interface includes a request input interface, as shown in fig. 2b, the request input interface may be in the form of an input box, and the technician may enter identification information of a distributed system that needs to perform topology analysis into the request input interface in the form of the input box and input confirmation information (e.g., directly pressing an enter key of a keyboard) to input an analysis request, where the analysis request carries the identification information of the distributed system that needs to perform topology analysis. Correspondingly, when the topology analysis device determines the target distributed system to be subjected to topology analysis according to the received analysis request, the distributed system indicated by the identification information carried in the analysis request can be used as the target distributed system to be subjected to topology analysis.

For another example, the topology analysis interface shown in fig. 2B further includes an "open" control, on one hand, when the topology analysis device detects the trigger of the open control, a selection sub-interface (as shown in fig. 2C) is displayed on the topology analysis interface in an overlapping manner, and the selection sub-interface provides an icon of a distributed system capable of performing topology analysis, such as icons of distributed systems, such as distributed system a, distributed system B, distributed system C, distributed system D, distributed system E, and distributed system F, for a technician to search for and select an icon of the distributed system requiring topology analysis; on the other hand, after selecting the icon of the distributed system needing to be analyzed, the technician may trigger the confirmation control provided by the selection sub-interface to input an analysis request to the topology analysis device, where the analysis request is associated with the icon of the distributed system selected by the technician, and instruct the topology analysis device to use the distributed system selected by the technician as the target distributed system.

In addition, a person skilled in the art may set other specific implementation manners of inputting the analysis request according to actual needs, and the present invention is not limited to this specific implementation manner.

In 202, static analysis is performed on the functional units included in the target distributed system to obtain a static analysis result.

In the embodiment of the present invention, after receiving the analysis request and determining the target distributed system that needs to be subjected to topology analysis, the topology analysis device invokes the static analysis tool to perform static analysis on the functional units included in the target distributed system to obtain a static analysis result, for example, if the target distributed system includes N functional units, the topology analysis device invokes the static analysis tool to perform static analysis on the N functional units included in the target distributed system, and obtains N static analysis results through analysis. For different functional units, the topology analysis device can respectively call the static analysis tools corresponding to the functional units to perform static analysis.

As an alternative embodiment, "performing static analysis on the functional units included in the target distributed system" includes:

and performing static analysis on the source code of the functional unit included in the target distributed system.

For example, when performing static analysis on a functional unit included in a target distributed system, taking a functional unit a as an example, at this time, the topology analysis device first obtains a source code of the functional unit a, then calls a static analysis tool to perform semantic analysis on the source code of the functional unit a, that is, performs analysis on context-related properties on the source code of the functional unit a, and identifies elements such as classes, functions, and variables in the source code.

As another alternative implementation, "performing static analysis on the functional units included in the target distributed system" includes:

and statically analyzing the compiling process file of the functional unit included in the target distributed system.

The compiling process file includes, but is not limited to, a compiling script, a header file, a compiling log, and the like of the source code of the functional unit at the time of compiling.

For example, when performing static analysis on a functional unit included in a target distributed system, taking a B functional unit as an example, at this time, the topology analysis apparatus does not perform static analysis on the source code itself of the B functional unit, but performs static analysis on a compilation process file of the source code of the B functional unit. The topology analysis device firstly acquires a compiling script, a header file and a compiling log corresponding to a source code of the B function unit, then performs static analysis on the acquired compiling script, the header file and the compiling log, and analyzes a call relation among different functions of the B function unit to serve as a static analysis result.

At 203, the function modules included in the functional units are identified according to the static analysis results corresponding to the functional units.

In the embodiment of the present invention, after completing the static analysis of the functional units included in the target distributed system, the topology analysis device further identifies the functional modules included in the functional units according to the static analysis result corresponding to the functional units.

For example, taking C function unit as an example, according to the static analysis result of C function unit, the internal function call relationship can be obtained as shown in fig. 2d, where function 1 can call function 2, function 2 can call functions 3 and 4, function 3 can call function 6 and 8, function 4 can call function 5 and 8, function 5 can call function 7, and function 6 can call function 9, and based on the call relationship of the internal function of C function unit, the function in which other functions can be called and the function called by other functions are identified as the function module of C function unit.

At 204, the functional unit pairs having call relationships are identified according to the functional modules included in the functional units.

The functional unit pair with the calling relationship refers to that one functional unit remotely calls the other functional unit, or one functional unit is remotely called by the other functional unit.

In the embodiment of the present invention, after identifying and obtaining the function modules included in the function units of the target distributed system, the topology analysis apparatus further identifies the function unit pairs having a call relationship according to the function modules included in each function unit. Specifically, "identifying a functional unit pair having a call relationship according to a function module included in each functional unit" includes:

(1) identifying a first function module which realizes a remote call interface function in function modules included in each function unit, and identifying a second function module which realizes a remote call client function in the function modules included in each function unit;

(2) combining the first function module and the second function module of different function identification units in pairs to establish a function module pair;

(3) and identifying a matched target function module pair from the established function module pair, and taking the two function units corresponding to the target function module pair as the function unit pair.

When the topology analysis device identifies a function unit pair having a call relationship according to function modules included in each function unit pair, first, a function module that implements a remote call interface function among the function modules included in each function unit is identified and recorded as a first function module, and a function module that implements a remote call client function among the function modules included in each function unit is identified and recorded as a second function module.

For example, the remote invocation must be performed through a network Protocol (such as a TCP/IP Protocol, Transmission Control Protocol/Internet Protocol), and the topology analysis device may identify a first function module that implements a remote invocation interface function in the function modules included in the function units and a second function module that implements a remote invocation client function in the function modules included in the function units according to whether the function modules use a basic API of the TCP/IP Protocol.

For example, referring to fig. 2e, continuing to take C function unit as an example, where the function module 1 is identified as a first function module implementing the remote call Interface function and identified by using an Interface, and the function module 7, the function module 8, and the function module 9 are identified as a second function module implementing the remote call Client function and identified by using a Client.

After identifying the first function module and the second function module of each functional unit included in the target distributed system, the topology analysis device further combines the first function module and the second function module of different functional units in pairs to establish a function module pair.

For example, the target distributed system includes a function unit a, a function unit B, a function unit C, and a function unit D, and the topology analysis device combines the first function module of the function unit a with the second function modules of the function unit B, the function unit C, and the function unit D, respectively, to obtain 3 function module pairs; combining the first function module of the B function unit with the second function modules of the A function unit, the C function unit and the D function unit respectively to obtain 3 function module pairs; combining the first function module of the C function unit with the second function modules of the A function unit, the B function unit and the D function unit to obtain 3 function module pairs; and combining the first function module of the D function unit with the second function modules of the A function unit, the B function unit and the C function unit to obtain 3 function module pairs. Thus, a total of 12 function module pairs are established.

After the function module pair is established, the topology analysis device further identifies a target function module pair matched with the first function module and the second function module from the established function module pair, so that two functional units corresponding to the identified target function module pair are used as functional unit pairs with calling relations. Wherein. The first function module and the second function module are matched, namely that the data which can be provided by the first function module is the same as the data which needs to be called by the second function module.

For example, a function module pair is composed of a first function module of the a function unit and a second function module of the D function unit, and if the first function module of the a function unit can provide the a data and the second function module of the D function unit needs to call the a data, the topology analysis device determines that the first function module of the a function unit and the second function module of the D function unit are matched. Correspondingly, the a functional unit and the D functional unit are a functional unit pair having a call relationship, and the a functional unit is called by the D functional unit, or the D functional unit calls the a functional unit.

Specifically, the "identifying a matching target function module pair from the established function module pairs" includes:

(1) acquiring a protocol definition of a first function module in a pair of function modules;

(2) and judging whether the second function module in the function module pair has the code characteristics defined by the corresponding protocol, if so, judging that the function module pair is the target function module pair, and otherwise, judging that the function module pair is not the target function module pair.

It should be noted that the remote call of a remote call interface must conform to the protocol definition of the remote call interface, and the remote call interface can be correctly routed to the remote call interface, for example, a fixed URL is used for convention in the REST protocol, for example, in the protobuf protocol, a proto file is used for describing the protocol. Correspondingly, the code characteristics corresponding to the protocol definition of the called end must exist in the source code of the calling end of the remote call, so that the data which can be provided by the called end is ensured to be the same as the data which needs to be called by the calling end.

For example, a function module pair is composed of a first function module of the a function unit and a second function module of the D function unit, the topology analysis device firstly analyzes the first function module of the a function unit to obtain the protocol definition of the first function module of the a function unit, then, the code analyzer is used for analyzing the code characteristics of the second function module of the D function unit, and whether the second function module of the D function unit has the code characteristics defined by the protocol of the first function module corresponding to the A function unit is judged, if yes, then the function module pair consisting of the first function module of the a function unit and the second function module of the D function unit is determined as the objective function module pair, and if not, it is determined that the pair of function blocks composed of the first function block of the a function unit and the second function block of the D function unit is not the pair of objective function blocks.

In 205, a call topology corresponding to the target distributed system is generated according to the determined pair of functional units.

In the embodiment of the present invention, after identifying all the functional unit pairs having a call relationship in the functional units of the target distributed system, the topology analysis device further summarizes the call relationship of each functional unit pair according to the determined functional unit pair to generate a call topology of the functional units included in the target distributed system, where the call topology describes the call relationship between the functional units in the target distributed system.

For example, the target distributed system includes a functional unit a, a functional unit B, a functional unit C, and a functional unit D, and the generated call topology is as shown in fig. 2f, according to which the functional unit a and the functional unit B both call the functional unit C, and in addition, the functional unit B also calls the functional unit D.

Optionally, after "generating a call topology corresponding to the target distributed system according to the determined pair of functional units", the method further includes:

and if the service flow corresponding to the target distributed system is received, distributing the service flow according to the calling topology.

It should be noted that, a distributed system deployed in a distributed manner generally provides services for a large number of clients at the same time, and if the service traffic from the clients cannot be effectively distributed, the distributed system may be crashed and cannot provide services continuously.

Therefore, in the embodiment of the present invention, when receiving the service traffic corresponding to the target distributed system, the service traffic may be distributed among the functional units of the target distributed system according to the call topology corresponding to the target distributed system, for example, load balancing of the job traffic in the functional units of the target distributed system, so as to implement effective distribution of the service traffic, and enable the target distributed system to efficiently provide services to the user side.

and if the abnormal functional unit in the target distributed system is detected, generating an evaluation report according to the influence range of the abnormal functional unit in the calling topology evaluation.

It should be noted that, a distributed system deployed in a distributed manner generally includes a large number of functional units, and when an exception occurs in a functional unit, the functional unit will affect other functional units, and in order to be able to remove the exception well, it is necessary to quickly evaluate the scope of the exception.

Therefore, in the embodiment of the invention, when the functional unit is detected to be abnormal, the influence range can be evaluated according to the corresponding calling topology of the target distributed system, and a corresponding evaluation report is generated for technicians to accurately eliminate the abnormality.

if the changed functional unit in the target distributed system is detected, other functional units having a calling relation with the changed functional unit are identified according to the calling topology, and the other functional units are correspondingly changed.

It should be noted that, in order to better provide services to the user terminal, the functional units of the distributed system deployed in a distributed manner are usually iterated continuously, and when one functional unit is changed, if the functional units on the upstream and downstream sides (i.e., other functional units called by the changed functional unit and other functional units calling the changed functional unit) are not changed correspondingly, the distributed system cannot provide services to the user terminal normally.

Therefore, in the embodiment of the present invention, when the changed functional unit in the target distributed system is detected, other functional units called by the changed functional unit and calling the changed functional unit may be identified according to the calling topology corresponding to the target distributed system, and then the identified other functional units may be changed accordingly.

As can be seen from the above, this embodiment may receive an analysis request, determine, according to the analysis request, a target distributed system that needs to perform topology analysis, where the target distributed system includes a plurality of functional units, then perform static analysis on the functional units included in the target distributed system to obtain a static analysis result, identify, according to the static analysis result corresponding to the functional units, function modules included in the functional units, identify, according to the function modules included in the functional units, a pair of functional units having a call relationship, and finally generate, according to the determined pair of functional units, a call topology corresponding to the target distributed system, thereby implementing efficient discovery of the call topology of the functional units in the distributed system. And then, when the management requirement of the target distributed system exists, the management can be correspondingly carried out according to the generated calling topology.

Example II,

The method according to the preceding embodiment is illustrated in further detail below by way of example.

In this embodiment, the topology analysis apparatus will be described by taking an example in which the topology analysis apparatus is specifically integrated in an electronic device.

As shown in fig. 3, the specific process of the topology analysis method may be as follows:

in 301, the electronic device receives an analysis request, and determines a target distributed system that needs to perform topology analysis according to the analysis request, where the target distributed system includes a plurality of functional units.

In the present invention, the electronic device may receive the analysis request in a number of different ways.

For example, the electronic device may provide a topology analysis interface to the technician, where the topology analysis interface includes a request input interface, as shown in fig. 2b, the request input interface may be in the form of an input box, and the technician may enter identification information of the distributed system that needs to perform topology analysis in the request input interface in the form of the input box and input confirmation information (e.g., directly pressing an enter key of a keyboard) to input an analysis request, where the analysis request carries the identification information of the distributed system that needs to perform topology analysis. Correspondingly, when the electronic device determines the target distributed system to be subjected to topology analysis according to the received analysis request, the distributed system indicated by the identification information carried in the analysis request can be used as the target distributed system to be subjected to topology analysis.

For another example, the topology analysis interface shown in fig. 2B further includes an "open" control, on one hand, when the electronic device detects that the open control is triggered, a selection sub-interface (as shown in fig. 2C) is displayed on the topology analysis interface in an overlapping manner, and the selection sub-interface provides an icon of a distributed system capable of performing topology analysis, such as icons of distributed systems, such as distributed system a, distributed system B, distributed system C, distributed system D, distributed system E, and distributed system F, for a technician to search for and select an icon of the distributed system requiring topology analysis; on the other hand, after selecting the icon of the distributed system needing to be analyzed, the technician may trigger the confirmation control provided by the selection sub-interface to input an analysis request to the electronic device, where the analysis request is associated with the icon of the distributed system selected by the technician, and instruct the electronic device to use the distributed system selected by the technician as the target distributed system.

In 302, the electronic device performs static analysis on the source code of the functional unit included in the target distributed system to obtain a static analysis result.

In the embodiment of the present invention, after receiving the analysis request and determining the target distributed system that needs to perform topology analysis, the electronic device invokes the static analysis tool to perform static analysis on the functional units included in the target distributed system to obtain a static analysis result, for example, if the target distributed system includes N functional units, the electronic device invokes the static analysis tool to perform static analysis on the N functional units included in the target distributed system, and then obtains N static analysis results through analysis. For different functional units, the electronic device can respectively call the static analysis tools corresponding to the functional units to perform static analysis.

For example, when performing static analysis on a functional unit included in a target distributed system, taking a functional unit a as an example, at this time, the electronic device first acquires a source code of the functional unit a, then invokes a static analysis tool to perform semantic analysis on the source code of the functional unit a, that is, performs analysis on context-related properties on the source code of the functional unit a, and identifies elements such as classes, functions, and variables in the source code of the functional unit a.

In 303, the electronic device identifies a function module included in the function unit according to the static analysis result corresponding to the function unit.

In the embodiment of the invention, after the electronic device completes the static analysis of the functional units included in the target distributed system, the function modules included in the functional units are further identified according to the static analysis results corresponding to the functional units.

In 304, the electronic device identifies a first function module, which implements the remote call interface function, among the function modules included in each function unit, and identifies a second function module, which implements the remote call client function, among the function modules included in each function unit.

The electronic equipment identifies a function module for realizing the remote call interface function in the function modules included in the function units and records the function module as a first function module, and identifies a function module for realizing the remote call client function in the function modules included in the function units and records the function module as a second function module.

For example, the remote invocation must be performed through a network Protocol (such as a TCP/IP Protocol, Transmission Control Protocol/Internet Protocol), and the electronic device may find that the remote invocation occurs according to whether the function module uses a basic API of the TCP/IP Protocol, so as to identify a first function module that implements a remote invocation interface function in the function modules included in the function units, and identify a second function module that implements a remote invocation client function in the function modules included in the function units.

In 305, the electronic device combines the first function module and the second function module of different function identification units two by two to establish a function module pair.

For example, the target distributed system includes a function unit a, a function unit B, a function unit C, and a function unit D, and the electronic device combines the first function module of the function unit a with the second function modules of the function unit B, the function unit C, and the function unit D, respectively, to obtain 3 function module pairs; combining the first function module of the B function unit with the second function modules of the A function unit, the C function unit and the D function unit respectively to obtain 3 function module pairs; combining the first function module of the C function unit with the second function modules of the A function unit, the B function unit and the D function unit to obtain 3 function module pairs; and combining the first function module of the D function unit with the second function modules of the A function unit, the B function unit and the C function unit to obtain 3 function module pairs. Thus, a total of 12 function module pairs are established.

In 306, the electronic device takes the function module pair having the code feature corresponding to the protocol definition of the first function module as the target function module pair in the second function module, and takes the two function units corresponding to the target function module pair as the function unit pair having the call relation.

After the electronic device establishes the function module pair, a target function module pair matched with the first function module and the second function module is further identified from the established function module pair, so that two function units corresponding to the identified target function module pair are used as a function unit pair with a calling relation. Wherein. The first function module and the second function module are matched, namely that the data which can be provided by the first function module is the same as the data which needs to be called by the second function module.

For example, a function module pair is composed of a first function module of the a function unit and a second function module of the D function unit, the electronic device first analyzes the first function module of the a function unit to obtain the protocol definition of the first function module of the a function unit, then, the code analyzer is used for analyzing the code characteristics of the second function module of the D function unit, and whether the second function module of the D function unit has the code characteristics defined by the protocol of the first function module corresponding to the A function unit is judged, if yes, then the function module pair consisting of the first function module of the a function unit and the second function module of the D function unit is determined as the objective function module pair, and if not, it is determined that the pair of function blocks composed of the first function block of the a function unit and the second function block of the D function unit is not the pair of objective function blocks.

At 307, the electronic device generates a call topology corresponding to the target distributed system according to the determined pair of functional units.

In the embodiment of the invention, after identifying all the functional unit pairs with calling relations in the functional units of the target distributed system, the electronic device further integrates the calling relations of all the functional unit pairs according to the determined functional unit pairs to generate the calling topology of the functional units included in the target distributed system, wherein the calling topology describes the calling relations among the functional units in the target distributed system.

At 308, if a management requirement for the target distributed system is detected, the electronic device manages the target distributed system according to the calling topology of the target distributed system.

For example, the electronic device may determine that a management requirement for the target distributed system exists when detecting a service traffic corresponding to the target distributed system, and distribute the service traffic among the functional units of the target distributed system according to the call topology, so as to implement management of the target distributed system,

For another example, the electronic device may determine that a management requirement for the target distributed system exists when detecting that the functional unit in the target distributed system is abnormal, and generate an evaluation report according to an influence range of the functional unit with the abnormal topology evaluation, thereby implementing management of the target distributed system.

For another example, when detecting that a functional unit in the target distributed system is changed, the electronic device may determine that a management requirement for the target distributed system exists, identify, according to the call topology, another functional unit having a call relationship with the changed functional unit, and correspondingly change the other functional unit, thereby implementing management of the target distributed system.

Example III,

In order to better implement the above method, an embodiment of the present invention further provides a topology analysis apparatus, which may be specifically integrated in an electronic device, such as a terminal or a server, for example, a mobile phone, a tablet computer, a notebook computer, or a PC.

For example, as shown in fig. 4, the topology analysis apparatus can include a request receiving component 401, a static analysis component 402, a module identification component 403, a relationship identification component 404, and a topology analysis component 405 as follows:

(1) a request receiving component 401;

the request receiving component 401 is configured to receive an analysis request, and determine a target distributed system that needs to perform topology analysis according to the analysis request, where the target distributed system includes a plurality of functional units.

In the present invention, the request receiving component 401 may receive the analysis request in a number of different ways.

For example, the request receiving component 401 may provide, to the technician through the electronic device where the request receiving component is located, a topology analysis interface that includes a request input interface, as shown in fig. 2b, where the request input interface may be in the form of an input box, and the technician may enter identification information of a distributed system that needs to be subjected to topology analysis into the request input interface in the form of the input box and input confirmation information (e.g., directly pressing an enter key of a keyboard) to input an analysis request, where the analysis request carries the identification information of the distributed system that needs to be subjected to topology analysis. Correspondingly, when determining the target distributed system that needs to be subjected to topology analysis according to the received analysis request, the request receiving component 401 may use the distributed system indicated by the identification information carried in the analysis request as the target distributed system that needs to be subjected to topology analysis.

For another example, in the topology analysis interface shown in fig. 2B, an "open" control is further included, on one hand, when the request receiving component 401 detects that the open control is triggered, a selection sub-interface (as shown in fig. 2C) is superimposed and displayed on the topology analysis interface, and the selection sub-interface provides an icon of a distributed system capable of performing topology analysis, such as icons of distributed systems, e.g., distributed system a, distributed system B, distributed system C, distributed system D, distributed system E, and distributed system F, for a technician to search for and select an icon of the distributed system that needs to perform topology analysis; on the other hand, after selecting the icon of the distributed system that needs to be analyzed, the technician can trigger a confirmation control provided by the selection sub-interface to input an analysis request to the request receiving component 401, the analysis request being associated with the icon of the distributed system selected by the technician, instructing the request receiving component 401 to treat the distributed system selected by the technician as the target distributed system.

(2) A static analysis component 402;

and the static analysis component 402 is configured to perform static analysis on the functional units included in the target distributed system to obtain a static analysis result.

In the embodiment of the present invention, after receiving the analysis request and determining the target distributed system that needs to perform topology analysis, the static analysis component 402 invokes a static analysis tool to perform static analysis on the functional units included in the target distributed system to obtain a static analysis result, for example, if the target distributed system includes N functional units, the static analysis component 402 invokes the static analysis tool to perform static analysis on the N functional units included in the target distributed system, and obtains N static analysis results through analysis. Wherein, for different functional units, the static analysis component 402 can respectively call the static analysis tool for each functional unit to perform static analysis.

As an alternative embodiment, in performing static analysis on the functional units included in the target distributed system, the static analysis component 402 may be configured to:

For example, when performing static analysis on a functional unit included in a target distributed system, taking a functional unit a as an example, at this time, the static analysis component 402 first obtains a source code of the functional unit a, then calls a static analysis tool to perform semantic analysis on the source code of the functional unit a, that is, performs analysis on context-related properties on the source code of the functional unit a, and identifies elements such as classes, functions, and variables in the source code, in addition, the static analysis component 402 also compiles the source code of the functional unit a by using a compiler to obtain an output in a compiling process, and further analyzes a call relationship between different functions in the functional unit a as a static analysis result in combination with a previous identification result of elements such as classes, functions, and variables in the source code of the functional unit a.

As another optional implementation, in performing static analysis on the functional units included in the target distributed system, the static analysis component 402 may further be configured to:

For example, when performing static analysis on a functional unit included in a target distributed system, taking B functional unit as an example, at this time, the static analysis component 402 does not perform static analysis on the source code itself of the B functional unit, but performs static analysis on the compilation process file of the source code of the B functional unit. The static analysis component 402 first obtains the compilation script, the header file, and the compilation log corresponding to the source code of the B function unit, then performs static analysis on the obtained compilation script, the header file, and the compilation log, and analyzes a call relationship between different functions of the B function unit as a static analysis result.

(3) A module identification component 403;

and a module identification component 403, configured to identify a function module included in the functional unit according to the static analysis result corresponding to the functional unit.

In this embodiment of the present invention, after the static analysis component 402 completes the static analysis on the functional units included in the target distributed system, the module identification component 403 further identifies the function modules included in the functional units according to the static analysis result corresponding to the functional units.

(4) A relationship identification component 404;

the relationship identifying component 404 is configured to identify a functional unit pair having a calling relationship according to a function module included in each functional unit.

In this embodiment of the present invention, after the module identification component 403 identifies and obtains the function modules included in the function units of the target distributed system, the relationship identification component 404 further identifies the function unit pairs having a call relationship according to the function modules included in each function unit. Specifically, when identifying a functional unit pair having a call relationship according to a function module included in each functional unit, the relationship identifying component 404 may be configured to:

identifying a first function module which realizes a remote call interface function in function modules included in each function unit, and identifying a second function module which realizes a remote call client function in the function modules included in each function unit;

combining the first function module and the second function module of different function identification units in pairs to establish a function module pair;

and identifying a matched target function module pair from the established function module pair, and taking the two function units corresponding to the target function module pair as the function unit pair.

When identifying a function unit pair having a call relationship according to the function modules included in each function unit pair, the relationship identification component 404 first identifies a function module that implements a remote call interface function among the function modules included in each function unit, and records the function module as a first function module, and identifies a function module that implements a remote call client function among the function modules included in each function unit, and records the function module as a second function module.

For example, the remote call must be performed through a network Protocol (such as a TCP/IP Protocol, Transmission Control Protocol/Internet Protocol), and the relationship identifying component 404 may identify a first function module that implements a remote call interface function in function modules included in each functional unit and a second function module that implements a remote call client function in function modules included in each functional unit according to whether the function module uses a basic API of the TCP/IP Protocol.

After identifying the first function module and the second function module of each functional unit included in the target distributed system, the relationship identification component 404 further combines the first function module and the second function module of different functional units two by two to establish a function module pair.

For example, the target distributed system includes a function unit a, a function unit B, a function unit C, and a function unit D, and the relationship identification component 404 combines the first function module of the function unit a with the second function modules of the function unit B, the function unit C, and the function unit D, respectively, to obtain 3 function module pairs; combining the first function module of the B function unit with the second function modules of the A function unit, the C function unit and the D function unit respectively to obtain 3 function module pairs; combining the first function module of the C function unit with the second function modules of the A function unit, the B function unit and the D function unit to obtain 3 function module pairs; and combining the first function module of the D function unit with the second function modules of the A function unit, the B function unit and the C function unit to obtain 3 function module pairs. Thus, a total of 12 function module pairs are established.

After the function module pair is established, the relationship identifying component 404 further identifies a target function module pair in which the first function module and the second function module are matched from the established function module pair, so as to take two function units corresponding to the identified target function module pair as a function unit pair having a call relationship. Wherein. The first function module and the second function module are matched, namely that the data which can be provided by the first function module is the same as the data which needs to be called by the second function module.

For example, a function module pair is composed of a first function module of the a function unit and a second function module of the D function unit, and if the first function module of the a function unit can provide the a data and the second function module of the D function unit needs to call the a data, the relationship identifying component 404 determines that the first function module of the a function unit and the second function module of the D function unit are matched. Correspondingly, the a functional unit and the D functional unit are a functional unit pair having a call relationship, and the a functional unit is called by the D functional unit, or the D functional unit calls the a functional unit.

In particular, upon identifying a matching pair of objective function modules from the established pair of function modules, relationship identification component 404 can be configured to:

acquiring a protocol definition of a first function module in a pair of function modules;

and judging whether the second function module in the function module pair has the code characteristics defined by the corresponding protocol, if so, judging that the function module pair is the target function module pair, and otherwise, judging that the function module pair is not the target function module pair.

For example, a function module pair is composed of a first function module of the a function unit and a second function module of the D function unit, the relationship identification component 404 first analyzes the first function module of the a function unit to obtain the protocol definition of the first function module of the a function unit, then, the code analyzer is used for analyzing the code characteristics of the second function module of the D function unit, and whether the second function module of the D function unit has the code characteristics defined by the protocol of the first function module corresponding to the A function unit is judged, if yes, then the function module pair consisting of the first function module of the a function unit and the second function module of the D function unit is determined as the objective function module pair, and if not, it is determined that the pair of function blocks composed of the first function block of the a function unit and the second function block of the D function unit is not the pair of objective function blocks.

(5) A topology analysis component 405;

and the topology analysis component 405 is configured to generate a call topology corresponding to the target distributed system according to the determined functional unit pair.

In this embodiment of the present invention, after the relationship identification component 404 identifies all the functional unit pairs having a call relationship in the functional units of the target distributed system, the topology analysis component 405 further summarizes the call relationship of each functional unit pair according to the determined functional unit pair to generate a call topology of the functional units included in the target distributed system, where the call topology describes the call relationship between the functional units in the target distributed system.

Optionally, the topology analysis apparatus further includes a distributed system management module, after the topology analysis component 405 generates a call topology corresponding to the target distributed system according to the determined functional unit pair, configured to:

if receiving the service flow corresponding to the target distributed system, distributing the service flow according to the calling topology; alternatively, the first and second electrodes may be,

if the abnormal functional unit in the target distributed system is detected, generating an evaluation report according to the influence range of the abnormal functional unit in the calling topology evaluation; alternatively, the first and second electrodes may be,

Therefore, in the embodiment of the present invention, when receiving the service traffic corresponding to the target distributed system, the distributed system management module may distribute the service traffic among the functional units of the target distributed system according to the call topology corresponding to the target distributed system, for example, load balancing of the job service traffic in the functional units of the target distributed system, so as to implement effective distribution of the service traffic, and enable the target distributed system to efficiently provide services to the user side.

Therefore, in the embodiment of the present invention, when detecting that an abnormality occurs in a functional unit, the distributed system management module may estimate the influence range of the target distributed system according to the corresponding call topology of the target distributed system, and generate a corresponding estimation report for a technician to accurately eliminate the abnormality.

Therefore, in the embodiment of the present invention, when detecting the changed functional unit in the target distributed system, the distributed system management module may identify, according to the call topology corresponding to the target distributed system, other functional units called by the changed functional unit and calling the changed functional unit, and then change the identified other functional units accordingly.

It should be noted that, in a specific implementation, each of the above components may be implemented as an independent entity, or may be optionally combined to be implemented as one or several entities, and the specific implementation of each of the above components may refer to the foregoing method embodiment, which is not described herein again.

As can be seen from the above, the request receiving component 401 of the topology analysis apparatus of the present embodiment can receive the analysis request, and determine the target distributed system that needs to perform the topology analysis according to the analysis request, the target distributed system comprises a plurality of functional units, and then the static analysis component 402 performs static analysis on the functional units comprised by the target distributed system to obtain a static analysis result, and the module identification component 403 identifies the function modules included in the function units according to the static analysis results corresponding to the function units, the relationship identification component 404 identifies the function unit pairs having call relationships according to the function modules included in the function units, and finally the topology analysis component 405 generates the call topology corresponding to the target distributed system according to the determined function unit pairs, thereby realizing efficient discovery of the call topology of the function units in the distributed system. And then, when the management requirement of the target distributed system exists, the management can be correspondingly carried out according to the generated calling topology.
