Description

Message tracking method and device, electronic equipment and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a message tracking method and apparatus, an electronic device, and a storage medium.

Background

More and more enterprises are faced with various data integration and system integration, and RPC middleware technologies such as CORBA, DCOM, RMI and the like are produced accordingly. The existing micro-service architecture is to split the whole service into a plurality of micro-service components with definite functions, the micro-service components are distributed and deployed on a server, and the micro-service components are mutually called through an RPC middleware technology. That is, the existing microservice tracking scheme is based on tracking of RPC calls, each RPC basic unit span includes two processes, i.e., as shown in fig. 1, after an RPC client sends a request (cs) at the current time, the server receives the request (sr) after 100ms of the current time; after the server side carries out corresponding processing on the received request, a response (ss) of the request is sent after 200ms of the current time, and the client side receives the response (cr) after 300ms of the current time. Wherein cs: a client start, which represents a client initiating a request;

sr: a server receive, which indicates that the server receives the request;

ss: server send, which indicates that the server finishes processing and sends the result to the client;

cr: and the client receive indicates that the client acquires the return information of the server.

In the RPC call tracking method, a server and a client record the upper and lower limits of a time stamp of an RPC. The call delay time of each node (such as a server or a client) is recorded for a complete RPC call chain, and the operation condition of each node is monitored in real time through the delay time.

However, the inventor finds that, because the RPC adopts a synchronous processing technology, and one traffic flow passes through a plurality of micro-service components, the client must wait for the response of the corresponding server to record the RPC call chain of the traffic, which results in low timeliness of message tracking.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present application without any creative effort belong to the protection scope of the present application.

The message tracking method provided by the embodiment of the invention can be applied to the distributed system shown in fig. 1. As shown in fig. 1, the system may include: the system comprises a publishing client, a subscribing client and a Message service end, wherein the Message service end can be Message-oriented middleware (MOM).

A service Application module (APP) in a subscription client performs subscription registration with a service Application module in a corresponding release client through message middleware to establish a service association relationship;

when the service application module in the publishing client publishes the message, the message is published to the service application module in the corresponding subscribing client through the message middleware.

The message middleware is used for performing platform-independent data communication by using an efficient and reliable message transfer mechanism and performing integration of a distributed system based on data communication. By providing a messaging and message queuing model, it can extend inter-process communication in a distributed environment. The message middleware can communicate among different platforms, realize the cooperation among different APPs, and can provide synchronous and asynchronous connection between the client and the server, so that the message can be transmitted or stored and forwarded at any time.

The message middleware is asynchronous, and supports an asynchronous publishing/subscribing mode, namely, sending and receiving are asynchronous, a sender does not need to wait for response so as to ensure normal transmission of messages when a distributed system fails, and the sender can indirectly transmit the messages to a plurality of receivers, so that the performance, expandability and robustness of a program are improved.

As shown in fig. 2, the basic principle of message middleware publish/subscribe is as follows: the message middleware maintains a variable message buffer buf for each subscription client (consumer) of the message Topic (or "message type"), such as APP3 and APP4, independently, wherein the message middleware MOM classifies received messages through Topic. The message middleware copies published messages, such as messages with topic of topic1 published by APP1, APP2 and APP5, to the publishing clients, such as APP1 and APP2, and actively publishes the messages to the subscribing clients, such as APP3 and APP4, and the subscribing clients read and process the messages by monitoring readable events in the messages.

The message middleware may be a memory-type redis database. Redis is a Key-Value (Key-Value) database, and a Key corresponding to each service request is unique, and a Value corresponding to the Key is also unique. The keyword type is a character String type, and the value type can be a character String (String) type, a character String list (lists) type, a character String set (sets) type, an ordered character String set (sorted sets) type and a hash (hashs) type. That is, the Key-Value database can quickly search for the Value corresponding to the Key.

In one example, a Map object is defined and two sets of key-values are placed: key _ A is "ming" and the corresponding value is "1"; key _ B is "zi" and the corresponding value is "2", which is expressed as follows:

Map<String,int>map＝new HashMap<String,int>()；

map.put("ming",1)；

map.put("zi",2)；

based on the above expression, obtaining a "ming," such as map. get ("ming"), would result in a value of 1.

If it is needed to place key _ a as "ming" and the corresponding value is "3", such as map.put ("ming",3), since the message middleware already stores the key _ a of "ming" and the key has uniqueness, the value "1" corresponding to the originally stored key _ a will be overwritten and updated to be "ming" for key _ a and "3" for corresponding value.

In the distributed system shown in fig. 1, the message middleware is configured to receive an update message sent by a service application module in a publishing client, and when the update message is an initial key value update message, assign a trace identity (trace ID) to the initial key value update message, where the trace ID may be randomly generated or preconfigured; and searching the service application module in the subscription client associated with the service application module in the publishing client in the stored subscription information of the service application module, and sending a subscription notice comprising the tracking identification and the key value updating information to the service application module.

And the service application module in the publishing client is used for acquiring the key value updating information of the service application module and sending the initial key value updating information or the updating information to the message middleware, wherein the initial key value updating information comprises the key value updating information, and the updating information comprises the key value updating information and the tracking identification of the key value updating information.

The key value update information may include an updated key value, such as a new value of the service identifier key1, and an operation made by the service application module with respect to the updated key value.

And the service application module in the subscription client is used for receiving a subscription notice which is sent by the message middleware and comprises the tracking identification and the key value updating information, triggering a preset callback function according to the key value updating information, acquiring the key value updating information of the subscription application module, and then sending the updating information to the message middleware. And then, repeating the working process of the service application module in the publishing client by the service application module in the subscribing client, and repeating the steps until the message middleware cannot find the service application module associated with the service application module in the publishing client in the stored subscription information of the service application module, and at this moment, stopping sending the subscription notice and ending the process.

It should be noted that the service application module in each client communicates with the message middleware using a library function (MOM client) provided by the message middleware.

The preferred embodiments of the present application will be described below with reference to the accompanying drawings of the specification, it being understood that the preferred embodiments described herein are merely for illustrating and explaining the present invention and are not intended to limit the present invention, and that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Fig. 3 is a flowchart illustrating a message tracking method according to an embodiment of the present invention. As shown in fig. 3, the method may include:

step 310, the message middleware receives the update message sent by the current service application module.

Before executing the step, the current service application module obtains key value update information, where the key value update information may include an updated key value and an operation (hereinafter, referred to as an "operation corresponding to the updated key value") performed by the current service application for the updated key value, and the operation may be an operation of updating the key value, an operation of sending the key value update information, and the like.

And the current service application module sends an update message to the message middleware according to the acquired key value update information, so that the message middleware receives the update message sent by the current service application module.

When the current service application module is the service application module which initially acquires the key value updating information, the updating information comprises the identification of the current service application module and the key value updating information of the current service application module. When the current service application module is not the service application module which initially acquires the key value updating information, the updating information comprises the tracking identifier, the identifier of the current service application module and the key value updating information of the current service application module.

Step 320, the message middleware determines whether the update message includes a tracking identification.

If the update message does not include the tracking identifier, the message middleware analyzes the update message after generating the tracking identifier of the update message to obtain the identifier of the current service application module and the key value update information of the current service application module.

The current service application module sending the update message is the service application module which initially acquires the key value update information, so that the identifier of the historical service application module is set as a preset root identifier, and the identifier of the historical service application module is the identifier of the service application module which is stored in the message middleware and which is passed through last before the tracking identifier passes through the current service application module.

And combining the generated tracking identifier, the set preset root identifier, the identifier of the current business application module and the key value updating information of the current business application module into the tracking information of the current business application module so as to obtain the tracking information of the current business application module.

If the update message comprises the tracking identification, the message middleware analyzes the update message to obtain the tracking identification of the update message, the identification of the current service application module and the key value update information of the current service application module.

Because the current service application module sending the update message is not the service application module which initially acquires the key value update information, the tracking identifier in the operation log is inquired about the identifier of the last passed historical service application module before passing through the current service application module;

and combining the tracking identification, the identification of the historical service application module, the identification of the current service application module and the key value updating information of the current service application module into the tracking information of the current service application module so as to obtain the tracking information of the current service application module.

In one example, the information structure of the tracking information is shown in fig. 4, and includes: a Trace identification (Trace ID) field, an identification (CurrentModuleID) field of the current APP, namely an identification field of the current service application module, an identification (LastmoduleID) field of the historical APP, namely an identification field of the historical service application module, and an operation (Action) field, namely an operation field corresponding to the updated Key value and a Key-value field after updating.

If the current APP is a service application module which initially obtains the key value update information, the lastmodule id field is a preset root identifier, such as a root, so that the tracking information of the current APP includes the generated tracking identifier, the identifier of the current APP, the root, the updated key value and the operation corresponding to the updated key value.

If the current APP is not the service application module which initially obtains the key value update information, the LastmoduleID field is the identifier of the APP which is passed through by the tracking identifier before the current APP passes through, so that the tracking information of the current APP comprises the generated tracking identifier, the current APP identifier, the identifier of the historical APP, the updated key value and the operation corresponding to the updated key value.

Optionally, after obtaining the trace information of the current business application module, the message middleware writes the trace information into the operation log.

Further, in order to form a message trace chain, the message middleware needs to associate the same trace ID, but if a trace ID field is simply added in a key-value storage structure, the trace ID field is idle when the message trace is not opened, which results in memory waste.

The existing Redis stores key-value in a character string array, and the character string array storing the key-value is dynamically allocated when being initially set. The embodiment of the invention stores the tracking identifier in a newly added field adjacent to a field where the key value updating information of the current service application module is located, namely, the trace ID field is placed behind the character string array of the key-value. The structure of the memory bank is shown in fig. 5, which includes:

a key-value field;

key-value length field (len): the length of the key is stored;

0 terminator field: indicating that the key is finished, and ensuring the normal use of the key;

alloc field: identifying the length of the entire storage structure;

header field (head): 1 byte, which identifies whether trace ID or other types are stored;

trace identification field (trace ID): and 64bit, storing trace ID of the key.

An indication field: and identifying the number of storage nodes behind the key-value, wherein 1 head field and one trace ID field are used as one storage node.

Step 330, the message middleware detects whether the stored subscription information of the service application module has an associated service application module associated with the service of the current service application module.

The subscription information of the service application module includes an identification of at least one associated service application module having an association (or "subscription") with the current service application module.

If the subscription information of the service application module contains at least one identifier associated with the service application module, executing step 340; if not, the flow ends.

Step 340, the message middleware sends a subscription announcement including the tracking identifier and the key value update information of the current business application module to the associated business application module.

And the message middleware sends a subscription notice comprising the tracking identifier and the key value updating information of the current service application module to the associated service application module according to the identifier of the associated service application module.

And 350, the associated service application module triggers a preset callback function according to the key value updating information of the current service application module, and acquires the key value updating information of the associated service application module.

The associated service application module triggers a preset callback function registered by the associated service application module according to the updated key value in the key value updating information of the current service application module, and acquires the key value updating information of the associated service application module, wherein the key value updating information comprises the updated key value of the associated service application module associated with the updated key value of the current service application module and the operation corresponding to the updated key value. The updated key value of the associated service application module not only has an association relation with the updated key value of the current service application module, but also can be the same as the updated key value of the current service application module.

After obtaining the key value updating information, the associated service application module sends an updating message to the message middleware. Since the associated service application module is not the service application module that initially obtained the key value update information, the update message includes the tracking identifier, the identifier of the associated service application module, and the key value update information of the associated service application module.

The associated service application module may be the new current service application module in step 310, and therefore step 310 is performed.

Furthermore, by analyzing the operation log of the current service application module, the operation log of the associated service application module and the operation log of the message middleware, message tracking and abnormal positioning of the service application module can be realized.

Specifically, the operation log of the current service application module, the operation log of the associated service application module and the operation log of the message middleware are extracted, the same trace ID in the operation logs is associated, and a message tracking chain of the trace ID can be obtained, so that message tracking is realized, and the real-time performance of message tracking is improved.

Detecting whether key value updating information is recorded in an operation log of a current service application module or an operation log of an associated service application module;

if not, determining that the working state of the current service application module or the associated service application module is abnormal;

if so, detecting whether the write-in time period of key value updating information recorded in the operation log of the current service application module or the operation log of the associated service application module is greater than a preset time period threshold value;

and if the writing time period is greater than the preset time period threshold, determining that the working state of the current service application module or the associated service application module is abnormal.

And if the writing time period is not greater than the preset time period threshold, determining that the working state of the current service application module or the associated service application module is normal.

In an example, taking 3 APPs, APP0, APP1, and APP2, and APP2 does not have an associated APP3 in the distributed system as an example, as shown in fig. 6, the message tracking method may include:

step 601, obtaining first key value updating information by the APP 0;

the first key value update information is the initial key value update information.

Step 602, the APP0 sends a first update message to the first message middleware according to the obtained first key value update information, where the first update message includes an identifier of the APP0 and the first key value update information of the APP 0.

The first update message includes the identifier of APP0 and the updated key value in APP0 and the operation corresponding to the updated key value.

Step 603, the first message middleware generates a tracking identifier of the first update message, and obtains tracking information of the APP 0.

The tracking information of the APP0 includes a tracking identifier, an identifier of the APP0, a preset root identifier, and first key value update information.

Step 604, the first message middleware detects whether an APP1 associated with the service existence of the APP0 exists in the stored subscription information of the APP;

if yes, go to step 605;

if not, go to step 615.

Step 605, the first message middleware sends a first subscription announcement to the APP 1.

The first subscription announcement includes a tracking identity and first key update information of the APP 0.

Step 606, the APP1 triggers the preset callback function according to the first key value update information of the APP0, and obtains second key value update information corresponding to the first key value update information of the APP 0.

The second key value updating information of the APP1 includes an identifier of the APP1 and second key value updating information of the APP1, where the second key value and the first key value have an association relationship.

Step 607, APP1 sends a second update message to the second message middleware.

The second update message includes an identification of APP1 and second key value update information of APP 1.

Step 608, the second message middleware obtains the tracking information of the APP 1.

The tracking information of APP1 tracks the identity of APP1, the identity of APP0, and the second key update information of APP 1.

Step 609, the second message middleware detects whether the stored subscription information of the APP has an APP2 associated with the service existence of the APP 1;

if yes, go to step 610;

if not, go to step 615.

Step 610, the message middleware sends a second subscription announcement to the APP 2.

The second subscription announcement includes the tracking identity and second key update information of the APP 1.

Step 611, triggering the preset callback function by the APP2 according to the second key value update information of the APP1, and acquiring third key value update information corresponding to the second key value update information of the APP 1.

The third key value update information of the APP2 includes an identifier of the APP2 and third key value update information of the APP2, wherein the third key value is associated with the second key value.

Step 612, APP2 sends a third update message to the third message middleware.

The third update message includes an identification of APP2 and third key value update information of APP 2.

Step 613, the third message middleware acquires tracking information of the APP 2.

The tracking information of APP2 tracks identity, identity of APP2, identity of APP1, and third key value update information of APP 2.

Step 614, the third message middleware detects whether the stored subscription information of the APP has the APP3 associated with the business of the APP 2;

since APP2 does not have an associated APP3, step 615 is performed.

And step 615, ending the process.
