Step 302, it is determined that the function (here for function a) that the needs that user chooses from the function being provided monitor.
It should be noted that, in the present invention, function a is a general reference function just, does not specifically limit a certain function.
Step 303, the supervision utilizing function a corresponding requires to write supervision script.
As mentioned above, it is necessary, function, it describes performance, it is evident that it also has certain performance requriements, and based on this, in step 303, the supervision utilizing function a corresponding requires to write and monitors that script is specially:
The performance requriements corresponding to performance utilizing function a to describe writes supervision script.
Step 304, becomes machine code by supervision script compile.
Specifically, in step 304, by script compile device, supervision script compile is become machine code.
When monitoring that script compile becomes machine code, its execution efficiency when the performance that supervision function in real time is corresponding is very high, and almost can not increase any burden for original program.
Step 305, distributes one piece of internal memory in process to be monitored, and machine code step 304 compiled writes in this internal memory.
Step 306, when calling function a, first jumps to internal memory and performs the machine code in internal memory, and to realize the execution of described supervision script, after the machine code in internal memory is finished, redirect performs function a.
Step 306 first calls described supervision script in above-mentioned steps 103, when described supervision script is called complete, continues to call a specific implementation of described function.
Within step 306, jump to the machine code that internal memory performs in described internal memory to comprise:
Beginning at function adds the first redirect (jmp) assembly instruction, to jump to the machine code that described internal memory performs in described internal memory.
Here, the first redirect assembly instruction can comprise the address information of internal memory, based on this address information, then can conveniently jump to the machine code that internal memory performs in described internal memory.
In the present invention, after the machine code for ensureing in step 306 in internal memory is finished, redirect performs function, can comprise further:
Finally add the 2nd jmp assembly instruction at machine code, perform function a with redirect;
Here, the 2nd jmp assembly instruction can comprise the address information of function a, based on this address information, then can conveniently jump to function a.
Based on this, in step 306, after the machine code in internal memory is finished, redirect performs function a and comprises:
Function a is performed according to the 2nd jmp assembly instruction redirect of machine code in the internal memory performed. Here, when the 2nd jmp assembly instruction of machine code in the internal memory performed, it is meant that the machine code in internal memory is finished.
So far, complete the flow process shown in Fig. 3.
Can be found out by the flow process shown in Fig. 3, in the present invention, the supervision script compile write for function is become machine code, can performance corresponding to Real-Time Monitoring function by this machine code, reach the object of Real-Time Monitoring performance, and, can orient, according to this performance Real-Time Monitoring, the source causing performance bottleneck in time when performance bottleneck, quick position goes out to affect the factor of performance, it is to increase program operational efficiency.
