How do I monitor the computer's CPU, memory, and disk usage in Java?

Question

I would like to monitor the following system information in Java:

• Current CPU usage** (percent)
• Available memory* (free/total)

• Available d

Answer 1

Make a batch file "Pc.bat" as, typeperf -sc 1 "\mukit\processor(_Total)\%% Processor Time"

You can use the class MProcess,

/*
 *Md. Mukit Hasan
 *CSE-JU,35
 **/
import java.io.*;


public class MProcessor {

public MProcessor() {
    String s;
    try {
        Process ps = Runtime.getRuntime().exec("Pc.bat");
        BufferedReader br = new BufferedReader(new InputStreamReader(ps.getInputStream()));
        while((s = br.readLine()) != null) {
            System.out.println(s);
        }
    }
    catch( Exception ex ) {
        System.out.println(ex.toString());
    }
}

}

Then after some string manipulation, you get the CPU use. You can use the same process for other tasks.
