First, read the core number of server CPU, such as, by the processor field under reading/proc/cpuinfo file, or cpucores field determines the core number of CPU.Wherein, processor field is for showing the maximum core numbering of CPU, and the core due to CPU is by 0 open numbering, therefore, if the processor field read is 3, the core that so can obtain CPU is numbered 0,1,2,3, that is the core number of CPU is 4.In addition, cpucores field is for showing the core number of CPU, if reading cpucores field is 4, the core number that so directly can obtain CPU is 4.
The core number supposing to obtain CPU is 4, represents 4 cores of CPU respectively with CPU0, CPU1, CPU2, CPU3.
Read the cpu resource consumption data total1 of current time, concrete, the cpu resource consumption data of current time can be obtained by the data in reading/proc/stat file.Under linux system, CPU usage is divided into User space, systematic thinking way and Idle state, represents that CPU is in the time of User space execution respectively, the time that system kernel performs, and the time that idle systems process performs.CPU usage refers to: CPU perform nonsystematic idle process time/CPU total time of implementation.
In the kernel of Linux, there is global variable a: Jiffies.Jiffies represents the time.Its unit is different with the difference of hardware platform.Define a constant HZ in system, represent the number of per second kind of minimum interval.The unit of such jiffies is exactly 1/HZ.The unit of Intel platform jiffies is 1/100 second, the minimum interval that system that Here it is can be differentiated.Each CPU time sheet, Jiffies will add 1.Total be exactly the occupancy of CPU with perform User space+systematic thinking way Jiffies divided by Jifffies represent.
Suppose reading/proc/stat file, the cpu resource consumption data obtained is as shown in table 1:
Table 1
| col1 | col2 | col3 | col4 | col5 | col6 | col7 | col8 | |
| CPU | 58881059 | 276558 | 79626046 | 39233433523 | 12364186 | 847076 | 14038754 | 0 |
| CPU0 | 22740763 | 118390 | 39867589 | 9768789325 | 6115347 | 847070 | 11388298 | 0 |
| CPU1 | 5773426 | 50387 | 9885799 | 9831592484 | 2241835 | 0 | 323006 | 0 |
| CPU2 | 18818718 | 51212 | 14915724 | 9813169718 | 2681267 | 2 | 230148 | 0 |
| CPU3 | 11548151 | 56568 | 14956931 | 9819881995 | 1325735 | 3 | 2097299 | 0 |
In table 1, the data representation that CPU is expert at be total cpu resource consumption data, the cpu resource consumption data of core CPU 0 that what CPU0 represented is, the cpu resource consumption data of core CPU 1 that what CPU1 represented is, the cpu resource consumption data of core CPU 2 that what CPU2 represented is, the cpu resource consumption data of core CPU 3 that what CPU3 represented is.Suppose the cpu resource consumption data (time of implementation that namely CPU is total) representing current time with total1, so, cpu resource consumption data total1 corresponding to each core can utilize formula (1) to calculate:
total1＝col1+col2+col3+col4+col5+col6+col7+col8.(1)
Wherein, what col1-col8 represented respectively is the cpu resource consumption data that this core arranges at 1-8, and unit is jiffies.What suppose to calculate is the cpu resource consumption data of core CPU 0, so total1 (CPU0)=
58881059+276558+79626046+39233433523+12364186+847076+14038754。
Wherein, col4 and col5 is the free time consumption data of operating system configuration, the namely time of CPU executive system idle process, so, at described current time, the resource data used1 for the treatment of process actual consumption in each core of client-requested can be calculated by formula (2):
used1＝total1-col4-col5.(2)
What suppose calculating is at described current time, for the treatment of the cpu resource consumption data of process resource data used1 core CPU 0 of actual consumption in core CPU 0 of client-requested, so used1 (CPU0)=total1 (CPU0)-39233433523-12364186.
Suppose that the predetermined sampling period is 10 seconds, so obtain current time each core cpu resource consumption data total1 and according to the free time consumption data of resource consumption data total1 and system configuration, calculate the process for the treatment of client-requested, in each core of described current time actual consumption resource data used1 after, through 10 seconds, then obtain cpu resource consumption data total2.That is, suppose that current time is t0, the predetermined sampling period is 10 seconds, so when t0+10, obtain cpu resource consumption data total2, and calculate through 10 seconds time according to said method, for the treatment of the resource data used2 of process actual consumption in each core of described current time of client-requested, recycling formula (3) calculates the CPU usage P of process in each core for the treatment of client-requested:
P＝(used2-used1)/(total2-total1)*100％.(3)
After the CPU usage P of the process for the treatment of client-requested of calculating in each core, judge whether the CPU usage of each core exceedes described predetermined threshold.Suppose that the CPU usage of core CPU0 exceedes predetermined threshold (such as 90%), then corresponding with this core process for the treatment of client-requested is refused to process the request from described client, other CPU occupation rates do not exceed the core CPU 1 of predetermined threshold, the process for the treatment of client-requested corresponding to CPU2, CPU3 then can continue to process the request from described client.
Understandable, according to the predetermined sampling period of different duration, the CPU occupation rate in different cycles can be obtained, get the shorter predetermined sampling period (such as 1 second), instantaneous CPU occupation rate can be calculated, get the longer predetermined sampling period (such as 10 seconds), can average load be calculated, namely can carry out peak clipping process to the burr of data, the data obtained are more accurate.
