Description
Technical Field
The present invention relates to the field of system testing technologies, and in particular, to a method, an apparatus, a device, and a readable storage medium for testing system time consumption.
Background
In high speed programmed systems, testing of the delay/speed of each module of the system has been an important method of evaluating the performance of each module in a programmed transaction system. The accurate speed test can accurately reflect the time consumption of each module of the system and provide an accurate optimization direction for the optimization and debugging of the system.
At present, due to the development of software and hardware technologies, the system time consumption of a programming system has already entered the single digit microsecond (microsecond) or even nanosecond (nanosecond) level, such as a programming trading system of financial security products, in which a market forwarding system can already achieve the time consumption approaching 100 nanoseconds.
Because the processing time of entering and exiting a subsystem/module in a programming/quantification system is one of the most important system performance indexes, the time-consuming measurement of the system is often carried out by repeatedly adopting various means in the process of development and use, and therefore how to carry out high-precision and interference-free measurement is always an important subject in the field.
For a developer of a programming system, the developer can use software to obtain a relatively accurate time stamp inside the system, record the time stamp in a critical path point to be measured, and analyze and count the recorded time stamp by matching with a proper data deriving and counting mode to obtain measurement data.
Because the time consumption of the whole system is very small, the performance consumption brought by the software testing process can not be ignored, and the CPU/memory resource of the system is additionally consumed to execute the corresponding function, the performance of the system can be obviously influenced, namely, the measurement method influences the measurement object, the measurement result can not accurately reflect the performance of the measurement object, and the detection accuracy is low; moreover, when the time of the system entering/exiting on a subsystem/module network layer is measured, the time stamp required by the method must be the time stamp of the same reference system (such as the same server), but different conditions exist when software enters the network segments of the system to be measured and exits from the system, the time stamps recorded by the system entering and exiting systems are not in the same absolute time axis, and the time stamp difference under different reference systems is large, so that the processing time consumption of the system can not be reflected; moreover, once the system needs to be modified, it is highly likely to affect the measurement codes themselves, requiring synchronous modification; in addition, as shown in fig. 1, a schematic diagram of implementing a conventional software processing time consumption testing method is shown, it can be seen that the time consumption measurement performed by using software only can be implemented by performing time consumption measurement on a system application layer, and two-way traversing time of four layers, namely a network hardware layer, a hardware driver layer, a system kernel layer and a system protocol stack, cannot be counted, and accurate measurement of the whole processing time consumption of a system to be tested cannot be implemented.
In summary, how to implement accurate measurement of the overall time consumption of the system while avoiding much influence on the operation of the system to be tested, and reduce the cost of time consumption test modification of the system under system change is a technical problem that needs to be solved by those skilled in the art.

Referring to fig. 2, fig. 2 is a flowchart illustrating a method for testing a system time consumption according to an embodiment of the present invention, the method including the following steps:

In the embodiment, at least one path of light is copied for the incoming and outgoing optical fiber signals of the system to be measured, and the optical fiber signals entering the system to be measured and the copied optical fiber signals have almost no time difference, so that the generated delay can be considered as 0, and therefore, the accurate time-consuming test can be realized for the detection of the copied optical fiber signals; and when the source data optical fiber signal is copied, the source data basically has no influence, namely the input optical fiber signal and the output optical fiber signal of the system to be tested basically have no influence, so that the influence on the actual operation of the system to be tested is avoided, and the real and time-consuming accurate measurement of the system can be realized.
In addition, in this embodiment, the (duplicated) in-out optical fiber signals of the system to be tested are directly tested, and the in-out optical fiber signals pass through the connection layer and the protocol layer of the system to be tested except the application layer, as shown in fig. 3, which is a test diagram of the system to be tested.
It should be noted that, in this embodiment, the device and the component for implementing the optical fiber signal copying are not limited, and may include an optical splitter, and the like, and the device capable of implementing the above function may be selected according to the actual device function.
S102, determining an input test signal and an output test signal corresponding to the input test signal;
generally, the length and processing difficulty of the input test signal should not be too large, otherwise, the test process will occupy more resources of the system, and may adversely affect the normal service operation of the system itself. Signals with shorter data lengths may generally be selected.
The output test signal is an output signal of the input test signal after the operation processing of the system to be tested, and the implementation manner of determining the output test signal is not limited in this embodiment, and the output test signal may be determined according to characteristics of the test system, such as data output time characteristics, output format characteristics, and data processing characteristics, or the input test signal may be input to the system to be tested to obtain an actual output signal as the output test signal. For example, the time interval of the system to be tested for outputting data according to each input data is large, and the output data corresponding to the data to be tested can be obtained from time one to one; for another example, the process of determining the input test signal and the output test signal corresponding to the input test signal may specifically include the following steps: determining data processing logic of a system to be tested; determining an input test signal; and carrying out data processing on the input test signal according to the data processing logic, and taking a signal obtained by the data processing as an output test signal. The data processing logic of the test system is determined, corresponding configuration is carried out in the execution main body, after the data to be detected are determined, data processing is carried out through the execution main body, and the output test signal corresponding to the input test signal is determined.

S103, identifying an input test signal in the input optical fiber signal;

The specific signal identification process and implementation manner may refer to the introduction of related technologies, and may be implemented by means of feature identification, signal matching, and the like, which are not described herein again.
In this embodiment, the execution sequence of step S103 and step S105 is not limited, step S103 may be executed first, or both steps may be executed simultaneously, and in fig. 2 provided in this embodiment, the parallel execution is taken as an example, and the output signal is generally later than the input signal, so that step S105 may be triggered at the start time no earlier than step S103, so as to avoid the consumption of useless power.
S104, if the input test signal is identified in the input optical fiber signal, recording the input time;
if an input test signal is identified in the input fiber signal, the time is recorded as the input time.
S105, identifying an output test signal in the output optical fiber signal;
and taking the determined output test signal as target data, performing matching detection on the output optical fiber signal of the system to be tested (obtained by copying) according to the target data, and judging that the input test signal is identified in the input optical fiber signal if the target data is detected. The step S103 can be referred to for implementation of this step, and details are not repeated here.
S106, if an output test signal is detected in the output optical fiber signal, recording output time;
if an output test signal is detected in the output fiber signal, the time is recorded as the output time.
And S107, calculating the processing time consumption according to the time difference between the input time and the output time.
Specifically, after the time for inputting the system to be tested (i.e., the input time) and the time for outputting the system to be tested (i.e., the output time) are obtained, an implementation process in the system time consumption calculation is specifically performed according to the input time and the output time, which is not limited in this embodiment, and a time difference between the input time and the output time may be directly used as the system time consumption, or a further accurate calculation of the system time consumption may be performed based on the time difference, which may refer to an implementation manner in the related art, and is not described herein again.
The output format of the time-consuming calculation output result can be compatible with the common network data packet format in the market at present, and the original content of the output file can be directly checked by third-party software such as wireshark and the like. The self-contained analysis tool which can adapt to various service data can be used for obtaining the final result and the statistical data at one time, the format is not limited in the embodiment, and the corresponding setting can be carried out according to the actual use requirement.
According to the technical scheme provided by the embodiment of the invention, through the copied optical fiber signal entering and exiting the system to be tested, the time difference between the optical fiber signal entering the system to be tested and the copied optical fiber signal is almost eliminated, so that the accurate time-consuming test can be realized for the detection of the copied optical fiber signal; when the source data optical fiber signal is copied, the source data is basically not influenced, namely the input optical fiber signal and the output optical fiber signal of the system to be tested are basically not influenced, so that the influence on the actual operation of the system to be tested is avoided, and the real and time-consuming accurate measurement of the system can be realized; the time-consuming tests such as data receiving, analysis and identification and the like are all executed by equipment running outside the system to be tested, so that the measurement environment has no influence on the resources of the system to be tested, the accurate test on the actual running state of the system to be tested can be realized, and meanwhile, as long as the network input and output of the system to be tested is in an optical fiber access mode, the method can be adopted for measurement no matter how the operating system, the network card type and the network access mode (optical fiber direct connection and access switch) of the system to be tested are, so that the application range of the test method provided by the application is wide, and the accurate test of different systems to be tested can be realized; in addition, in the method.
