Embodiment Construction

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thoroughly understood, and will fully convey the scope of the present disclosure to those skilled in the art.

[0028] The present invention is used in the code testing stage. Through the shared memory associated with the parent process and the child process, the tracking code is extracted, and the asynchronous process is used to complete the automatic positioning of the program performance bottleneck, and the current stack data is printed out for the child process that has timed out, which is conducive to positioning the Master- T...

Abstract

The invention discloses a code tracing method and a code tracing system. The method comprises the steps as follows: shared memory is established and stores state information of a plurality of sub-processes; whether current state duration of the sub-processes is overtime is judged according to the state information of the sub-processes stored in the shared memory; and if the duration is overtime, overtime sub-processes are traced by a parent process, and stacking information of the sub-processes is recorded. With the adoption of the code tracing method and the code tracing system, performance bottleneck of on-line service codes can be traced automatically.

Description

technical field [0001] The invention relates to a code tracking method and system thereof, in particular to a code tracking method and system for online service codes. Background technique [0002] The service code can find most of the performance bottlenecks during the test phase and optimize them for performance bottlenecks. However, the online environment is complex and changeable, and various problems may occur after the code goes online. When the quality of service decreases and the delay increases, it is necessary to use a certain method to locate the performance bottleneck and optimize it. [0003] In view of this, when a performance bottleneck occurs in the code, the performance bottleneck is usually initially located, the execution time of the key point is recorded and logged, and then the execution time of the key point is analyzed. If the execution time exceeds the set value, it will be recorded as A log file (Log), and finally locate the performance bottleneck b...
