Thread: How to propperly calculate the server load?

Curious as to how to about properly calculating the server's load? The way I did it (Which I don't believe was working correctly) was the following.

Code:

		scheduler.schedule(new Task() {
			@Override
			protected void execute() {
				long startTime = System.currentTimeMillis();
				itemHandler.process();
				playerHandler.process();
				npcHandler.process();
				shopHandler.process();
				CycleEventHandler.getSingleton().process();
				objectManager.process();
				fightPits.process();
				pestControl.process();
				ticks++;
				long endTime = System.currentTimeMillis();
				System.out.print("\n[Debug]: Server usage at ["+(int)(((endTime - startTime) / 600) * 100) + "%]"
						+ "\n[Debug]: Started at : " + startTime 
						+ "\n[Debug]: Ended at : " + endTime);
			}
		});

I'm not sure if I'm doing this correctly, but it seems that the startTime and the endTime are always equal to one another, and I doubt the entire server is processing in less than 1ms.
Considering startTime and endTime are always equal, the calculation in the end is equal to 0, displaying 0% server usage.


Help?
