getCpuLoad back to summary

getCpuLoad	back to summary
public double getCpuLoad() Implements com.sun.management.OperatingSystemMXBean.getCpuLoad. Doc from com.sun.management.OperatingSystemMXBean.getCpuLoad. Returns the "recent CPU usage" for the operating environment. This value is a double in the [0.0,1.0] interval. A value of 0.0 means that all CPUs were idle during the recent period of time observed, while a value of 1.0 means that all CPUs were actively running 100% of the time during the recent period being observed. The recent period of observation is implementation-specific, and typically relates to the duration since the last call made to this method, or `getSystemCpuLoad()`. For the very first invocation, the recent period of observation is undefined. All values between 0.0 and 1.0 are possible dependent on the activities going on. If the recent CPU usage is not available, the method returns a negative value.

public double getProcessCpuLoad() Implements com.sun.management.OperatingSystemMXBean.getProcessCpuLoad. Doc from com.sun.management.OperatingSystemMXBean.getProcessCpuLoad. Returns the "recent CPU usage" for the Java Virtual Machine process. This value is a double in the [0.0,1.0] interval. A value of 0.0 means that none of the CPUs were running threads from the JVM process during the recent period of time observed, while a value of 1.0 means that all CPUs were actively running threads from the JVM 100% of the time during the recent period being observed. Threads from the JVM include the application threads as well as the JVM internal threads. The recent period of observation is implementation-specific, and typically relates to the duration since the last call made to this method. For the very first invocation, the recent period of observation is undefined. All values between 0.0 and 1.0 are possible dependent on the activities going on in the JVM process and the whole system. If the Java Virtual Machine recent CPU usage is not available, the method returns a negative value.
