示例1: getProcessCpuLoad

import javax.management.AttributeList; //導入方法依賴的package包/類
public static double getProcessCpuLoad() throws Exception {

		MBeanServer mbs = ManagementFactory.getPlatformMBeanServer();
		ObjectName name = ObjectName.getInstance("java.lang:type=OperatingSystem");
		AttributeList list = mbs.getAttributes(name, new String[] { "SystemCpuLoad" });

		if (list.isEmpty())
			return Double.NaN;

		Attribute att = (Attribute) list.get(0);
		Double value = (Double) att.getValue();

		// usually takes a couple of seconds before we get real values
		if (value == -1.0)
			return Double.NaN;
		// returns a percentage value with 1 decimal point precision
		return value;
