Description
Technical Field
The embodiment of the invention relates to the technical field of software testing, in particular to a throughput control method, a device, equipment and a storage medium.
Background
A technique for obtaining an application log of an information system production environment under test and playing back the application log in the test environment is called traffic playback. The traffic playback is divided into traffic playback for the purpose of functional testing and traffic playback for the purpose of performance testing. The flow playback aiming at the function test has no requirement of throughput index, and the flow playback aiming at the performance test has higher requirement on the throughput of the test system.
Initially, flow playback for performance testing purposes often played back flow at the maximum capacity of the performance testing press. With the increasing importance of the industry on the performance indexes of information systems, some core application systems need to compare the performance difference between a new version and an old version every time the version is changed. An important performance testing method for comparing new and old versions is as follows: and performing flow playback on the new version and the old version of the application system at a fixed throughput, and comparing the difference of performance indexes such as response time, resource utilization rate and the like of the application system under the condition of the same throughput.
In the throughput control technology in current traffic playback, multiple threads (or multiple virtual users) are generally used to perform traffic playback simultaneously, and each thread sends an application log at a fixed step length (paging), that is, one application log is sent at fixed time intervals. In the conventional throughput control technique for traffic playback, when the difference in the size of the application log is large, it is difficult to stably control the throughput of the traffic playback. For example, 99% of logs in an application system are 1KB, and a press only needs 5 milliseconds to send out a log when playing back a log, but 1% of logs may be between 10KB and 10MB and occur randomly in size, and the press has a very long processing time and a non-fixed processing time (for example, between 50 milliseconds and 50 seconds) when playing back a large log. With the existing throughput control technique, each thread sends an application log with a fixed step size:
1) if the flow is played back by taking 40 milliseconds as a step length, when a large log between 10KB and 10MB is encountered, the processing time of the large log may be far beyond the step length of 40 milliseconds, and the subsequent log waits for the processing of the current large log to be completed, the step length setting is invalid, so that the flow playback cannot reach the preset throughput value.
2) If the traffic is played back in 50 seconds, the number of concurrent threads (or the number of virtual users) required to achieve the same throughput index will be 1250 times that of 40 milliseconds. Not only wastes a large amount of system resources, but also is easy to have the condition of uneven flow. Therefore, this setting method is not used in actual work.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only a part of the structures related to the present invention, not all of the structures, are shown in the drawings, and furthermore, embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
Example one
Fig. 1 is a flowchart of a throughput control method according to an embodiment of the present invention, where the embodiment is applicable to a situation where throughput of a press in a test system is stably controlled, and the method may be executed by a throughput control apparatus, and the apparatus may be implemented by software and/or hardware.
As shown in fig. 1, the method specifically includes the following steps:
and step 110, obtaining the current log sending start-stop time of the target thread of the press in the current sending period, and determining the current log sending duration according to the current log sending start-stop time.
In practical application, the application log generated by the tested information system in a production environment can be obtained, the application log is sent to the tested system by using a press machine in a testing environment, flow playback is carried out, and performance testing of the tested system is achieved. The number of the press machines can be one or a plurality of, and each press machine can also be provided with a plurality of threads in parallel.
During flow playback, in order to stabilize throughput, the press machine can be controlled to periodically send the application log, and the sending step length is preset to be the time interval of one sending period. For example, the sending step may be preset to be 40 milliseconds, and in the case that the application log can be sent to completion within 40 milliseconds, one thread of the press is triggered to send one application log every 40 milliseconds.
In this embodiment, one thread of a designated press is described, and this thread may be referred to as a target thread, and it is understood that each press and any thread thereof in the test system are applicable to the throughput control method provided in this embodiment.
Specifically, when the press sends an application log, the sending start time and the sending end time for sending the application log are recorded, and the sending time length for sending the application log can be calculated according to the sending start time and the sending end time and by combining the factors such as the working performance of the press. In the sending period of the current moment, the sending start-stop time of the current log can be obtained, and the sending duration of the current log is determined according to the sending start-stop time of the current log.
Alternatively, step 110 may be determined by:
step 1101, acquiring the current log sending start time and the current log sending end time of the target thread in the current sending period.
Specifically, the current log sending start time and the current log sending end time of the playback application log of the target thread in the current sending period are obtained, the current log sending start time may be recorded as T1, and the current log sending end time may be recorded as T2.
Step 1102, determining a sending response time length according to the current log sending start time and the current log sending end time.
Specifically, the difference between the current log transmission end time and the current log transmission start time may be used as the transmission response time period, i.e., T2-T1.
Step 1103, determining the random response time length according to the length of the time slice of the press processor and the adjusting parameter.
Specifically, the length of the press processor time slice, denoted as CPUSlice, and the adjustment parameter Para are obtained, and Rand CPUSlice Para is determined as the random response time length, wherein Rand is a random number between [0,1 ]).
And 1104, determining the sum of the sending response time length and the random response time length as the current log sending time length.
Specifically, the current log sending time length may be taken as Taction, Taction = (T2-T1) + Rand CPUSlice · Para.
And step 120, determining the current timeout condition of the current sending period according to the sending duration of the current log and by combining the accumulated timeout value of the last sending period.
The current timeout condition may include non-timeout transmission and timeout transmission, among others.
In this embodiment, an accumulative timeout variable OverTime may be set for each thread on the press, a value of the accumulative timeout variable OverTime may be referred to as an accumulative timeout value, and an initial value of the accumulative timeout variable may be 0, that is, OverTime = 0. When a certain log sending time length exceeds the preset sending step length, the overtime time can be cumulatively counted into the cumulative overtime variable, and the overtime time can be continuously recovered in the following sending period, so that the recovered overtime time is eliminated from the cumulative overtime variable.
Specifically, whether the application log corresponding to the transmission period can be completely transmitted within a preset transmission step length can be judged according to the current log transmission duration, and if yes, whether the timeout time is not recovered before the current transmission period is considered, that is, whether the accumulated timeout value of the previous transmission period is greater than zero is judged, and when the accumulated timeout value is greater than zero, the timeout time is not recovered. If the application logs corresponding to the sending period can be sent completely within the preset sending step length, and the remaining time after the sending is completed can be used for completely recovering the previous overtime or the previous overtime is cleared, it can be determined that the current overtime condition of the current sending period is not overtime sending, that is, the actual throughput of the application logs sent by the press is consistent with the preset throughput until the current sending period is ended, the actual throughput calculation mode is the ratio of the total sending number of the application logs to the total sending time, and the total sending time can be obtained by subtracting the time of starting sending the first log from the time of ending the current sending period. If the sending of the application log corresponding to the sending period cannot be completed within the preset sending step length, or the remaining time after the sending of the application log corresponding to the sending period is completed cannot be completely recovered from the previous overtime time, the current overtime condition of the current sending period can be determined as overtime sending, that is, the actual throughput of the application log sent by the press is lower than the preset throughput until the current sending period is finished, the actual throughput calculation mode is the ratio of the total sending number of the application logs to the total sending time, and the total sending time can be obtained by subtracting the time of the first log from the time of the current sending period.
Optionally, step 120 may be determined by:
step 1201, acquiring a preset sending step length, and determining the difference between the preset sending step length and the current log sending time length as the estimated sleep time length of the current sending period.
Specifically, the current log sending time length may be recorded as Taction, the preset sending step length is paging, the estimated sleep time length of the current sending period is Tsleep, and Tsleep = paging-Taction. It is understood that Tsleep may be a positive number, a negative number, or zero.
And 1202, acquiring an accumulated timeout value of the last sending period, and determining the accumulated timeout value of the current sending period by combining the estimated sleep time.
Further, step 1202 may be specifically implemented by the following method:
acquiring an accumulated timeout value of a last sending period, and determining that the accumulated timeout value of the current sending period is equal to zero when the estimated sleep time is greater than or equal to the accumulated timeout value of the last sending period; otherwise, determining that the accumulated timeout value of the current sending period is equal to the difference between the accumulated timeout value of the last sending period and the estimated sleep time.
Specifically, the value of the accumulated timeout variable may be zero or positive, the estimated sleep time may be negative, zero or positive, and when the estimated sleep time is greater than or equal to the accumulated timeout value of the previous transmission cycle, the following situations may be adopted: 1) the estimated sleep time Tsleep of the current sending period is more than or equal to 0, the OverTime =0 of the previous sending period indicates that the previous timeout time is cleared, and the application log corresponding to the sending period can be sent in time in the current sending period; 2) the estimated sleep time Tsleep of the current transmission period is greater than 0, the OverTime of the previous transmission period is greater than 0, and Tsleep is greater than OverTime, which indicates that the prior timeout time exists, but the prior timeout time can be completely recovered by the residual time after the application log corresponding to the current transmission period is completely transmitted, so that the accumulated timeout value can be set to zero in the above cases.
In addition, when the estimated sleep time is greater than or equal to the accumulated timeout value of the last sending period, the fact that the actual throughput of the application log sent by the press machine can be made to accord with the preset throughput before the current sending period is ended by adjusting the actual sleep time of the current sending period is explained. At this time, after the log is sent, thread sleep is executed, and the actual sleep duration of the current sending period may be determined to be the difference between the estimated sleep duration Tsleep and the accumulated timeout value OverTime of the previous sending period.
When the estimated sleep duration is less than the accumulated timeout value of the last transmission cycle, the following situations can be used: 1) the estimated sleep time Tsleep of the current sending period is more than or equal to 0, the OverTime of the previous sending period is more than 0, and the OverTime is more than Tsleep, which indicates that the application log corresponding to the current sending period can be sent in time in the current sending period, but the previous OverTime cannot be completely recovered; 2) the estimated sleep time Tsleep of the current sending period is less than 0, the OverTime of the previous sending period is more than or equal to 0, and the situation shows that the application log corresponding to the current sending period cannot be sent in time in the current sending period, so that the difference between the accumulated timeout value of the previous sending period and the estimated sleep time can be used as the accumulated timeout value of the current sending period.
Step 1203, when the cumulative timeout value of the current sending period is equal to zero, determining that the current timeout condition of the current sending period is not timeout sending; and when the accumulated timeout value of the current transmission period is greater than zero, determining that the current timeout condition is timeout transmission.
And step 130, determining next log sending time of the next sending period according to the current overtime condition, and controlling the target thread to send the next application log at the next log sending time.
Optionally, when the current timeout condition is no timeout sending, determining a time period from the current log sending end time to the actual sleep time as the thread sleep time, and determining the end time of the thread sleep time as the next log sending time of the next sending cycle; and when the current overtime condition is overtime transmission, determining the current log transmission ending time as the next log transmission time.
Specifically, when the current timeout condition is that the application log is not sent OverTime, that is, before the current sending period is ended, the actual throughput of the application log sent by the press machine conforms to the preset throughput, at this time, thread sleep can be executed after the log is sent, and the execution time of the thread sleep is thread sleep time, that is, the estimated sleep time Tsleep of the current sending period — the accumulated timeout value OverTime of the previous sending period. When the current timeout condition is timeout sending, that is, before the current sending period is ended, the actual throughput of the press sending the application log is lower than the preset throughput, so that the next application log sending operation needs to be directly started when the sending of the application log is ended. And when the current sending period is ended, the ideal period ending time corresponding to the current sending period is calculated by taking a preset sending step length as a period duration.
For example, an accumulative timeout variable OverTime in a single thread on the press may be set with an initial value of 0, i.e., OverTime = 0.
Controlling the press to play back the first application log and recording a starting time point T1 and an ending time point T2 of playing back the application log, wherein if the first log is a larger log, the time is longer:
t1=11 points 15 minutes 12 seconds 003 milliseconds,
t2=11 points 15 minutes 12 seconds 103 milliseconds,
calculating the log sending time Tation for replaying the application log:
Taction=（T2-T1）+Rand*CPUSlice*Para，
wherein Rand is a random number between [0,1), and the assumed value is 0.5; CPUSlice is the time slice length of the press CPU, assumed to be 10 milliseconds; para is a tuning parameter, assumed to be 1; then it is determined that,
taction =100 ms +0.5 x 10 ms x 1=105 ms.
Letting the preset sending step length Pacing =40 ms, calculating the sleep time Tsleep required after the application log is played back in the current sending period according to the preset step length Pacing:
tsleep = Pacing-Taction =40 ms-105 ms = -65 ms.
Tsleep = -65 ms, the cumulative timeout value OverTime =0- (-65) ms =65 ms of the current transmission period, the cumulative timeout value OverTime > 0 of the current transmission period, and the current timeout condition is timeout transmission, so after the application log is transmitted in the current transmission period, the transmission operation of the next application log is directly started.
And then entering a second sending period, wherein the current sending period is the second sending period, and the application log corresponding to the second sending period is assumed to be a smaller log, so that the consumed time is short:
t1=11 points 15 minutes 12 seconds 103 milliseconds,
t2=11 points 15 minutes 12 seconds 108 milliseconds,
calculating the log sending time Tation for replaying the application log:
Taction=（T2-T1）+Rand*CPUSlice*Para，
wherein: rand is a random number between [0,1), and the value is assumed to be 0.1; CPUSlice of 10 milliseconds; para is 1; then it is determined that,
taction =5 ms +0.1 x 10 ms x 1=6 ms.
Calculating the sleep time Tsleep required after the corresponding application log is played back in the current sending period according to the preset sending step length Pacing:
tsleep = paging-contact = 40-6-34 ms.
Acquiring an accumulated timeout value OverTime =65 ms of the last transmission cycle, and acquiring a sleep time Tsleep =34 ms of the current transmission cycle, where the timeout deduction condition is met: since the sleep time Tsleep (34 msec) of the current transmission cycle is less than the accumulated timeout value OverTime (65 msec) of the previous transmission cycle, the accumulated timeout value of the current transmission cycle is recorded as 65 msec-34 msec =31 msec, and after the application log is transmitted in the current transmission cycle, the transmission operation of the next application log is directly started.
And then entering a third sending period, wherein the current sending period is the third sending period, if the log played back in the third sending period is a smaller log, the required log sending time duration Taction is shorter, and assuming that the log is still 6 milliseconds, the corresponding sleep time Tsleep is still 34 milliseconds, the accumulated timeout value OverTime of the last sending period is 31 milliseconds, and at this time, a deduction condition is provided, and thread sleep can be executed, and the time duration Tsleep-OverTime =34 milliseconds-31 milliseconds =3 milliseconds. After the execution thread is asleep, a fourth sending cycle may be entered to send a fourth application log.
In the above example, after the third sending cycle is finished, the problem that the number of times of playing back the log in unit time is not as expected due to failure of the paging setting caused by the large log encountered in the first sending cycle can be recovered.
According to the technical scheme of the embodiment, the current log sending start-stop time of the target thread of the press in the current sending period is obtained, the current log sending time length is determined according to the current log sending start-stop time, the current overtime condition of the current sending period is determined according to the current log sending time length by combining the accumulated overtime value of the previous sending period, the next log sending time of the next sending period is determined according to the current overtime condition, and the target thread is controlled to send the next application log at the next log sending time. The invention records the accumulated sending overtime time before the current sending period by setting the accumulated overtime variable, and judges whether the previous overtime time can be recovered in the current sending period by combining the current log sending time of the current sending period, thereby specifically determining the next log sending time of the next sending period and continuously controlling the sending operation of the next application log, solving the problem that the throughput of the press machine can not be stably controlled due to the size difference of the application logs in flow playback, and realizing the stable maintenance of the throughput of the press machine in the test system in a wider time requirement by adjusting the actual sleep time of a local sending period.
On the basis of the foregoing technical solution, the throughput control method provided in this embodiment may further include:
and monitoring the throughput state of the target thread, and adjusting the adjusting parameter and/or the preset sending step length when the difference between the throughput state and the expected throughput state is greater than the preset stability difference.
Specifically, if the stability of the target linear control throughput of the press is not good, the Pacing value may be increased according to actual conditions, and the flow playback may be performed again until the throughput can be controlled more stably, for example, after one round of playback, the overall throughput is still unstable, and if the reason is determined that there are many large logs in the log, the Pacing value may be increased, for example, changing the preset sending step length of 40 milliseconds to 100 milliseconds, and performing the flow playback again until the throughput can be controlled more stably. Adjustment of the tuning parameters may also be considered if the throughput is overall higher or lower.
In addition, if flow playback is required at a high, steady throughput, and a single press or thread is insufficient to provide the required throughput, the number of press threads and the number of presses may be increased to achieve the desired throughput. For example, in the above example, the preset sending step length Pacing is set to 40 ms, the single-thread playback expected throughput is 25 pens/sec, if the expected throughput is 500 pens/sec, 5 presses may be set, the number of threads of each press per day is 4, and the expected throughput of each thread is 25 pens/sec, so that the total expected throughput may reach 500 pens/sec.
