Embodiment 1

[0047] figure 2 It is a schematic diagram of the counter setting of the method for judging whether a system or a system module is blocked according to an embodiment of the present invention;

[0048] Such as figure 2As shown, the application program includes 4 sub-modules, and a module counter is set in each sub-module. Since the module counter is set in the module, it is at the module level, and the counters of different sub-modules are not allowed to be named repeatedly.

[0049] Since sub-module 1, sub-module 3 and sub-module 4 do not call other internal modules, they are all independent modules, and their internal counters are independent counters. The counters in submodule 1, submodule 3, and submodule 4 only reflect the performance (thread blocking) of their corresponding submodules.

[0050] Submodule 2 is an intermediate module that calls submodule 3 and submodule 4. The value of counter 2 is the sum of the values ​​of counter 3 and counter 4. The dependency betw...

Embodiment 2

[0053] Figure 5 is a schematic flowchart of a system for judging congestion according to an embodiment of the present invention;

[0054] exist Figure 5 , the system sets a global counter (bv). The global counter bv is set in the system, and the addition and subtraction operations of the global counter bv are respectively performed at the entrance and exit of all modules in the system. The global counter can reflect the performance of the system (thread blocking).

[0055] 2. Counter counting (counting module)

[0056] A system or a system module is triggered (executed) according to different requests.

[0057] Such as figure 2 As shown, the browser client uses the HTTP interface to access the sub-module 1, the mobile APP uses the HTTP interface to access the sub-module 2, and other background services use the RPC (Remote Procedure Call Protocol, remote procedure call protocol) and SOCKET interface to call the sub-module 2.

[0058] There can be many kinds of request ...

Abstract

The invention provides a method and device for judging whether a system or a system module is blocked or not. By the method and the device, the threading blocking condition of the system or the systemmodule can be simply and effectively judged, the performance of the whole system and each module can be monitored, and judgment can be achieved under the condition of extremely low performance loss.The method comprises the steps of arranging a counter in the system or the system module; performing 1-adding operation on the counter each time when the system module is executed, and performing 1-subtraction operation on the counter if the system module is not blocked; and judging whether the system or the system module is a blocked system or system module if a value of the counter is higher than a threshold value.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for judging whether a system or a system module is blocked. Background technique [0002] Generally, large-scale Internet applications have the characteristics of high concurrency, massive users, and distributed architecture. The system will contain many sub-modules, and many sub-modules will involve the use of various locks, distributed queues, RPC remote calls, and distributed database operations. . Therefore, it is particularly important to quickly determine background performance problems, that is, once the service freezes, such as slow response, timeout, etc., it is necessary to quickly determine which system sub-module has a problem. [0003] In the prior art, a log frame (Apache Log4j, etc.) is used to print the execution time difference of the method, and the problematic module is determined by searching the execution time difference of each module ...
