Atitit. Get CPU Share of Java C #. NET PHP node. js the implementation

gain CPU share via WMIC interface

C:\users\administrator.attilaxpc188>wmic CPU Get Loadpercentage

Loadpercentage

71

Note: Average CPU usage is calculated

all we get is the instantaneous CPU usage, which takes a while for the average CPU to be better

second, get the CPU,is the total CPU, if you need to accurately guide each core occupancy, you can also use the detailed version of this command.

In addition, this WMIC interface is not able to get a numeric value when the CPU is busy, and may be an os problem. Strategy..

Lower CPU consumption

use sleep technology best suited. Can control the number of threadPool tasks in disguise.

public   static int getcpurate () throws  cantgetdata {

String getcpurate  = "WMIC CPU get Loadpercentage" ;

String ret = cmdx. exec (getcpurate);

logger "--wmic CPU:" ret );

string[] a  = ret . Split ("\ n");

list<string> Li = Lists. newarraylist ();

for (String string : a) {

String Line  = string . Trim ();

if (line. Length () = = 0)

Continue ;

Li . Add (line);

}

String CPU  = NULL ;

if (li. Size () = = 1)

Throw New cantgetdata (ret);

//String CPU = Li.get (Li.size ()-1);

try {

CPU  = Li . Get (1). toString (). Trim ();

} catch (Exception e) {

throw new

// }

return Integer. parseint (CPU. toString ());

}
