Hi !
I tried to figure out system load with this piece of code:
new Thread(new Runnable() {
public synchronized void run() {
long[] average = new long[5];
int pos = 0;
long sum = 0;
while (true) {
try {
this.wait(1000);
long time = System.currentTimeMillis();
for (int i=0; i<100; i++) {
Thread.yield();
}
long value = (System.currentTimeMillis() -
time);
System.out.println("Time: " + value);
sum -= average[pos];
average[pos] = value;
sum += value;
pos = (pos + 1) % average.length;
System.out.println("Average: "
+ (sum / average.length));
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}).start();
And it seems to do a pretty good job on my VM (Sun 1.4/Linux), which
doesn't necessairily mean it will give
good results in other environments (windows/kaffe etc.).
