Fig. 1 is a flowchart illustrating a pressure testing method according to an embodiment of the present disclosure, and as shown in fig. 1, the method may include:

in step 11, a pressure measurement information configuration page is displayed, and a plurality of pressure measurement configuration parameter items are loaded on the pressure measurement information configuration page.

Fig. 2 is a schematic diagram of a pressure measurement information configuration page provided according to an embodiment of the present disclosure, where in an embodiment, pressure measurement configuration parameter items are as items A1 to A5 in fig. 2, and necessary items and selectable items in the pressure measurement configuration parameter items may be selectively set according to an actual usage scenario to fit the usage scenario and usage requirements of a user.

In one possible embodiment, item A1 may be used to set the process name, item A2 may be used to set the target number of simulation clients launched in a single server for pressure; item A3 can be used for setting a test script to be executed by a test process, the test script can set a default script, and when a user does not input, the default script is used as the test script; item A4 is used to set an IP address of a pressure server, where the pressure server may be one or more, and if there are multiple pressure servers, the IP address of each pressure server may be input; the A5 entry is used to set the IP address of the compressed server.

In step 12, parameter information input for a pressure measurement configuration parameter item on a pressure measurement information configuration page is acquired, a pressure measurement instruction is generated according to the acquired parameter information in response to a configuration completion operation, and the pressure measurement instruction is sent to a pressure application server and used for starting a target number of simulation clients in the pressure application server, so that the simulation clients execute a target script to log in the pressure application server.

In this embodiment, parameter input may be performed on the pressure measurement information configuration page for different pressure measurement configuration parameter items, so as to complete setting of the parameter item, so as to obtain a parameter included in the pressure measurement instruction. The server for performing the pressure test is a server for simulating a plurality of clients to perform an access operation, for example, a plurality of simulation clients may be started in the server for performing the pressure test, each simulation client is used to simulate an access process of an actual client, and the server for performing the pressure test is a server that needs to perform the pressure test.

The configuration parameters corresponding to the pressure test configuration parameter item are parameter information required for performing a pressure test, for example, the configuration parameters may include, but are not limited to, an IP address of a pressure server, a target number of simulation clients that need to be started in each pressure server, a target script that needs to be executed by the simulation clients, an IP address of the pressure server, and the like. The target script is a script file for controlling the simulation process to be executed by the simulation client, i.e. a processing logic to be executed by the actual client for logging in the compression server is simulated. For example, the user may set and launch in a command line manner in the compressed server, or may set and launch through a command line based on other remote servers.

For each pressure measurement configuration parameter item, determining the content corresponding to the pressure measurement configuration parameter item in the content input by the user as the value of the pressure measurement configuration parameter item; in addition, for the parameter information which is not correspondingly input by the user in the pressure measurement configuration parameter item, the default value corresponding to the pressure measurement configuration parameter item can be determined as the value of the parameter information, so that the value of each pressure measurement configuration parameter item can be obtained, and the pressure measurement instruction can be further generated. As described in the example of fig. 2 above, the pressure measurement configuration parameter items are A1 to A5, and for example, the user may input corresponding contents for the setting items A1, A4, and A5 to perform setting, where the value of the item A1 is "Test _ name", the value of the item A2 is "100", the value of the item A4 is "10.86.146.145 32200, 10.119.127.55", and the value of the item A5 is "10.227.13.176. Correspondingly, the value of the A3 item is a default value of the item, such as a preset "xxx.

In this step, the pressure server may be one or more, and the setting of the target number may be set according to the pressure test requirement of the pressure server, which is not limited by this disclosure. For example, after sending the pressure measurement instruction to the pressure application server, the pressure application server may start a target number of simulation clients in the pressure application server in response to receiving the pressure measurement instruction and executing the pressure measurement instruction. As an example, for each server under pressure, it may implement the starting of a target number of simulation clients through a preset number of starting processes. For example, the target number may be 100, and the number of the start processes may be 3, where the 3 start processes may be set to start 33, and 34 simulation clients, respectively. Or the ratio of the simulation clients started by each starting process may be set, so as to implement the starting of the plurality of simulation clients, for example, the ratio is "1. It should be noted that there may be one or more pressure servers, and the number of corresponding start processes in each pressure server may be the same or different, which is not limited in this disclosure.

In step 13, server parameter information and CPU execution function information of the compression server during the execution process of the stress test are obtained, where the CPU execution function information includes execution layer type information corresponding to a function, and the execution layer type information is used to indicate an execution layer to which the execution function belongs.

The server parameter information is parameter information representing processing performance of a server, for example, memory occupation information, CPU occupation information, disk IO (Input/Output) information, and uplink and downlink traffic information of the server, where the uplink and downlink traffic information may include uplink traffic and downlink traffic. The CPU execution function information is information indicating a relevant function executed in the CPU of the pressure server during the execution of the pressure test.

In step 14, according to the server parameter information and the CPU execution function information, the abnormality existing in the pressure receiving server and the abnormality position corresponding to the abnormality are determined.

The server parameter information can be used for representing the running state of the server, the CPU execution function information can be used for representing the running state corresponding to the CPU, and therefore the abnormality of the server can be determined based on the running state of the server, the abnormal position can be determined through analyzing the CPU execution function information, and the accurate positioning of the abnormal reason is achieved.

Therefore, in the technical scheme, parameters required by the pressure test can be visually configured through a pressure test information configuration page to directly generate a pressure test instruction, the pressure test instruction is sent to the pressure application server to start the pressure test, server parameter information and CPU execution function information of the pressure application server in the pressure test execution process are acquired, and the abnormality of the pressure application server and the abnormal position corresponding to the abnormality are determined according to the server parameter information and the CPU execution function information. Through the scheme, the user can directly start the pressure testing process based on the pressure testing information configuration page, the setting is not required in a command line mode, the dotting test is not required in the pressure testing process, the error of a pressure testing result caused by dotting position deviation can be effectively avoided, the technical skill and experience requirements of technical personnel can be effectively reduced, and the user use experience is improved. In the technical scheme of this disclosure, can monitor the overall process of stress test, and monitor server performance and CPU's function execution simultaneously, thereby can be when the server performance is unusual, carry out function information and analyze and fix a position unusual reason based on CPU, improve the accuracy and the coverage of stress test, can accurately determine the abnormal position that needs optimize in the stress test process simultaneously, realize accurate analysis, and be convenient for the user to formulate the optimal measure, further promote user and use experience.

In a possible embodiment, the pressure measurement configuration parameter item includes a server setting item, and the server setting item includes a pressure server setting item and a pressure server setting item;

correspondingly, an example implementation manner of acquiring the parameter information input by the pressure measurement configuration parameter item on the pressure measurement information configuration page and generating the pressure measurement instruction according to the acquired parameter information in response to the configuration completion operation is as follows, where the step may include:

and responding to the selection operation of the user for the server setting item in the pressure measurement information configuration page, and displaying the connected server corresponding to the server setting item.

For example, a connection may be established in advance with a plurality of servers in the stress test system. For example, a plurality of servers participating in the stress test may perform pre-processing registration in the stress test system in advance, and establish a connection between the stress test system and the stress server and between the stress test system and the stressed server through a remote SSH (Secure Shell protocol). The SSH is an encrypted network transmission protocol, and can provide a safe transmission environment for network services in an unsafe network, so that the safety of data transmission in the pressure test process can be effectively ensured, and the safety of the pressure test is further ensured.

In a possible embodiment, when the stress testing system is started, the system can be connected with each registered server through SSH respectively, and when parameter information input for a pressure measurement configuration parameter item on a pressure measurement information configuration page is acquired, such as when a user configures the above items A4 and A5, each connected server can be displayed by pulling down at B1, so that the user can select a desired server from the displayed servers and add the server to the item A4. Likewise, the respective pressure servers to which the connection has been established may be displayed by being pulled down at B2, so that the user may select the pressure server from the displayed pressure servers to be tested and add to the item A5, thereby achieving the selected configuration of the pressure server and the pressure server.

And then responding to the selection operation of the user on the server, acquiring the parameter information corresponding to the selected server, and generating the pressure measurement instruction according to the parameter information.

In this embodiment, the configuration parameters corresponding to the service selected by the user may be determined based on the selection operation of the user, so that the configuration parameters may be used as the parameter information correspondingly input to the corresponding pressure measurement configuration parameter item, and the user does not need to manually input an IP address, thereby reducing the user operation, and simultaneously ensuring the accuracy of the IP address of the server, and ensuring the safety of the pressure test by making both the configured pressure application server and the pressure server be servers that have established a safety connection. Similarly, when setting for the A3 item, all the imported scripts may be displayed by pulling down at B3, so that the user may select one script from the displayed scripts as the test script.

In one possible embodiment, the user may view the various servers to which a connection is currently established through a server view list. For example, the user may click a view button in a front-end page of the stress testing system to trigger a server list request, and the back-end of the stress testing system may obtain, in response to the server list request, each registered server information through SSH and display the obtained server information through the front-end page, so that the user may view currently available servers.

Therefore, by means of the technical scheme, the servers can be managed in a unified mode, the servers and the compression servers can be managed in a unified mode, the pressure testing method is suitable for pressure testing requirements under various scenes, the application range of the pressure testing method is widened, connection with the servers does not need to be established for multiple times, and user experience is improved.

In a possible embodiment, as shown in fig. 2, a user may click all start buttons to trigger execution of a pressure test, so that a pressure test process may be started, and similarly, a user may click all stop buttons to trigger a stop instruction, and send the stop instruction to a pressure application server, so that the pressure application server closes a simulation client, thereby ending the pressure test process, and implementing unified management on multiple simulation clients in the pressure test process. The refresh state may be used to trigger refresh monitoring of a state of each simulation client, and the setting may be used to trigger a user to configure related information of the server, for example, to modify the type of the server, and for example, the type of the server may be modified from the server to the server under pressure and the server under pressure, so that a pressure test process for the server may be implemented in the pressure test system, which is convenient for the user to operate.

In one possible embodiment, the method may further comprise:

and displaying a server adding page, wherein the server adding page bears server parameter configuration items for a user to perform related setting.

By way of example, a user may trigger a page request by clicking on an add server button to display the server add page, as shown in FIG. 3.

And then, in response to an input operation of a user in the server adding page and aiming at a target configuration item in the server parameter configuration items, generating server connection information corresponding to a server to be connected according to the target configuration item and content input by the user, wherein the server connection information is used for establishing communication connection with the server to be connected, and exemplarily, the server connection information may include an IP address and SSH information of the server to be connected.

As shown in fig. 3, where may be used to indicate that the item is a must-fill setting item to prompt the user accordingly. The user fills in "server IP: after the content of the SSH port entry, the IP address and SSH information of the server to be connected can be obtained. Other server to-be-set items can be set as a required-to-fill setting item and an optional setting item according to actual use conditions. Similarly, the type of the server may be set as a "pressure & pressure" type by default, that is, the server to be connected may be used as a pressure server or a pressure server, and when the type of the server to be connected needs to be set, the user may select a corresponding type, so as to obtain the server connection information corresponding to the server to be connected.

The method for performing server connection based on the IP address and the SSH information may be implemented based on an SSH command, and is not described herein again.

Therefore, according to the technical scheme, a new server can be added through the visual interface, the connection with the server is established through the SSH, the unified management of the server is realized, the operation flow of pressure testing based on the server is effectively simplified, the server can be directly accessed after the connection is established, the connection is not required to be performed again in a command line mode subsequently, the management efficiency of the server is further improved, and the efficiency of the pressure testing can be improved to a certain extent.

In one possible embodiment, an exemplary implementation manner of obtaining server parameter information and central processing unit CPU execution function information of the pressure server during the pressure test execution process is as follows, and the step may include:

the method comprises the steps that server parameter information corresponding to the compression server is obtained based on a service monitoring system, wherein the server parameter information comprises performance parameter information corresponding to the compression server and performance parameter information corresponding to an execution process in the compression server.

The service monitoring system may persistently store the collected performance indicator data as time series data, i.e., a collection of consecutive data stored in a time dimension in the same order.

As an example, performance parameter information corresponding to the compressed server may be collected, such as CPU occupation information, memory occupation information, disk occupation information, and the like of the compressed server; and the performance parameter information corresponding to each execution process in the compressed server can be acquired, such as the CPU information and the memory information occupied by the current execution process, so as to acquire the server parameter information corresponding to the compressed server based on the above manner.

The CPU calling instruction can be obtained by sampling based on a preset sampling interval, and then corresponding execution function information can be obtained, the sampling interval can be set according to an actual use scene, for example, 10ms can be set, so that the CPU execution function information obtained by sampling can be closer to the actual function execution condition in the CPU through high-frequency sampling of the CPU calling instruction, and the accuracy of subsequent abnormal position analysis based on the CPU execution function information is ensured. Therefore, the performance of the server and the execution condition of the CPU are simultaneously obtained in the process of the pressure test, the collected execution function information and the server parameter information can be ensured to be in the same time period, and data support is provided for the subsequent abnormal position determination.

In an actual usage scenario, the game server is usually implemented by the engine layer and the script layer, and the functions of different layers are usually implemented in different languages, for example, the functions of the engine layer are usually used for basic underlying logic and usually implemented in C + +, and the functions of the script layer are usually used for upper business logic and usually implemented in scripting languages such as Lua or Python. Therefore, when the game server provides a service, it is generally necessary to go through a function method in the script layer to call a function method in the engine layer or a function method in the engine layer to call a function method in the script layer. In the related art, the pressure test analysis can be performed based on the perf provided by the Linux system, but the perf can only obtain the stack of C + +, so that the analysis of all execution functions is difficult to realize, and the accurate positioning of the exception is difficult to realize.

Based on this, the present disclosure provides the following embodiments. In this embodiment, the sampling interval time samples a CPU call instruction, and an exemplary implementation manner of obtaining the CPU execution function information is as follows, where the step may include:

and intercepting the system call at intervals of the sampling time so as to sample the CPU call instruction. For example, interception of Linux system calls may be implemented based on ptrace. Operating systems, among other things, typically provide services through a set of standard mechanisms called system calls. The system call provides a standard API for accessing underlying hardware and services (such as a file system), and ptrace provides a mechanism for enabling a parent process to observe and control the execution process of a child process, so that the system call of the child process can be tracked, and a CPU call instruction can be obtained. The specific use mode of the ptrace related command is the prior art, and is not described herein again.

And decoding the sampled CPU call instruction to obtain a call link corresponding to the CPU call instruction, wherein the CPU instruction can be decoded by adopting related decoding technology in the field, so that a function required to be called by executing the call instruction and a parent function of the function can be obtained, and the call link is obtained.

And then determining execution layer type information corresponding to an execution function according to the call link, adding the execution layer type information to stack frame information corresponding to the execution function, and taking the updated stack frame information as the CPU execution function information, wherein the execution layer type information comprises an engine layer and a script layer. Wherein the execution function is the last called method in the call link. For example, libunwind may be used to obtain corresponding stack frame information from the intercepted system call, so as to obtain stack frame information of each execution function.

As an example, a first calling method corresponding to a script layer method calling an engine layer method and a second calling method corresponding to an engine layer method calling the script layer method are determined, and the two calling methods are different, so that in one possible embodiment, it may be determined whether a calling link includes the first calling method and the second calling method, and when the link includes the first calling method or the second calling method, execution layer type information corresponding to an execution function may be determined based on the calling method. If the calling method before the execution function and closest to the execution function is the first calling method, the execution layer type information corresponding to the execution function is determined to be the engine layer, and if the calling method before the execution function and closest to the execution function is the second calling method, the execution layer type information corresponding to the execution function is determined to be the script layer.

Illustratively, a calling link is represented as { f1, f2, a, f3, f4, B, f5, a, f6}, where a is used to represent a first calling method, B is used to represent a second calling method, and f1-f6 are used to represent methods in the calling link, so that the executing function f6 can be determined as an executing function in the calling link, and a calling method which is before the executing function and is closest to the executing function is the first calling method a, then the executing layer type information corresponding to the executing function f6 can be determined as an engine layer.

As another example, a file corresponding to the execution function may be determined based on the call link, so that the execution layer type information corresponding to the execution function may be determined based on the type of the file, and if the file corresponding to the execution function is determined to be an xx.c file by the call link, that is, the type of the file is a C language type, the execution layer type information corresponding to the execution function may be determined to be the engine layer. If the file corresponding to the execution function is determined to be the xx.lua file by calling the link, that is, the type of the file is the Lua language type, then the execution layer type information corresponding to the execution function can be determined to be the script layer.

Therefore, by the technical scheme, the system call can be intercepted to obtain the CPU call instruction, and the call instruction is decoded, so that the execution function based on different languages contained in the CPU call instruction can be obtained, the comprehensiveness of pressure test data acquisition is improved, and the accuracy of subsequent pressure test result analysis is improved. Meanwhile, in the embodiment, the execution layer type information corresponding to the execution function can be identified, and the execution layer type information is added to the stack frame information corresponding to the execution function, so that the execution function can be classified and analyzed in the subsequent data analysis process, and accurate and reliable data support is provided for the subsequent determination of the position corresponding to the abnormality.

In a possible embodiment, the exemplary implementation manner of determining the abnormality existing in the server under pressure and the abnormality position corresponding to the abnormality according to the server parameter information and the CPU execution function information may include:

and under the condition that the server parameter information meets the abnormal condition, determining that the compressed server is abnormal, and determining the time period when the server parameter information meets the abnormal condition as an abnormal time period.

For example, for each piece of server parameter information, the corresponding exception condition may be that the server parameter information exceeds the corresponding exception threshold, and the exception threshold may be preset according to an actual usage scenario, if the exception threshold corresponding to the CPU occupancy information is 75%, it may be determined that the pressurized server is abnormal when the CPU occupancy information is greater than 75%, and at the same time, it may be determined that the exception is CPU occupancy exception. The manner of determining whether the other parameter information is abnormal is the same as that described above, and is not described herein again.

And determining the sampling times corresponding to each execution function in the abnormal time period.

In this embodiment, a corresponding abnormal time period may be determined according to the abnormality, so that the execution function information corresponding to the abnormal time period may be extracted from the CPU execution information acquired in the pressure test process for analysis, and each execution function information in the abnormal time period may be counted, thereby determining the sampling frequency corresponding to each execution function therein.

and determining the execution function with the corresponding abnormal value larger than a preset threshold value as an abnormal function, and determining the position corresponding to the abnormal function as the abnormal position.

If the ratio of the sampling frequency of a certain execution function to the sampling frequency of the execution function in the abnormal time period is greater than a preset threshold, that is, the execution time of the execution function in the abnormal time period is longer, the abnormal time period may be caused by the execution function, and the execution function may be determined to be an abnormal function in this case.

As an example, the location corresponding to the execution function may be a file corresponding to the execution function, and if the execution function E is located in the file xx.c, the determined abnormal location may be the xx.c file. As another example, the location corresponding to the execution function may be a file corresponding to the execution function and a line number of the execution function in the file, and if the execution function E is located in an nth line of the file xx.c, the determined exception location may be xx.c/N.

Therefore, by the technical scheme, the information of the CPU execution function in the abnormal time period can be analyzed, so that the reason causing the abnormality can be determined from the angle of the CPU execution function, the abnormal problem and the reason causing the abnormality can be accurately positioned, the accuracy and the precision of positioning the abnormal reason can be effectively improved, the user can be accurately prompted about the abnormal position, a worker can conveniently and timely accurately check the abnormality and make a corresponding solution, and the accuracy and the efficiency of the pressure testing method are improved.

As shown above, in the stack frame information corresponding to the execution function, the stack frame information may include execution layer type information corresponding to the execution function, and accordingly, in the above example, the exception location may further include execution layer type information corresponding to the execution function, for example, the exception location may be "xx.c/N: an engine layer ". In the in-service use process, because the engine layer and the script layer are usually developed by different developers, when the abnormal position is determined, the abnormal position can be prompted, corresponding developers can be prompted, the use requirements of the user are further fitted, and the use experience of the user is improved.

In one possible embodiment, the method may further comprise:

and generating a flame map (FlameGraph) according to the CPU execution function information in the time period corresponding to the abnormality, and displaying the flame map.

In this embodiment, the CPU execution function information may include a name of a function being executed by the CPU and a call stack (stack), so that a corresponding flame map may be generated based on the CPU execution function information. Which may be generated based on flame map generation tools commonly used in the art, and is not limited by the present disclosure.

Wherein, in the flame diagram, the y-axis direction is used to represent the call stack, and each layer is a function. The deeper the call stack, the higher the flame, the top is the function that is being executed and the bottom is the parent function of the function. The x-axis direction is used to indicate the number of samples, and if the width occupied by a function on the x-axis is wider, it indicates that it is decimated more times, i.e., executed for a longer time. If a "flat top" occurs in the flame diagram, indicating that the CPU is performing the same function during that time period, the function at that flat top may present performance problems. Therefore, in the embodiment, the collected CPU execution function is displayed through the flame diagram, so that the user can clearly determine the function execution process in the CPU in the pressure test process, and the user can accurately analyze the pressure test result.
