    • getSystemLoadAverage

      public double[] getSystemLoadAverage(int nelem)
      Returns the system load average for the number of elements specified, up to 3, representing 1, 5, and 15 minutes. The system load average is the sum of the number of runnable entities queued to the available processors and the number of runnable entities running on the available processors averaged over a period of time. The way in which the load average is calculated is operating system specific but is typically a damped time-dependent average. If the load average is not available, a negative value is returned. This method is designed to provide a hint about the system load and may be queried frequently.

      The load average may be unavailable on some platforms (e.g., Windows) where it is expensive to implement this method.

      Parameters:
      nelem - Number of elements to return.
      Returns:
      an array of the system load averages for 1, 5, and 15 minutes with the size of the array specified by nelem; or negative values if not available.
