org.rioproject.system.measurable.cpu
Class SystemCPUHandler

java.lang.Object
  org.rioproject.system.measurable.cpu.SystemCPUHandler

All Implemented Interfaces:

MeasurableMonitor<CpuUtilization>

public class SystemCPUHandler
extends Object
implements MeasurableMonitor<CpuUtilization>

CPU monitor that obtains system CPU utilization. This utility uses either Hyperic SIGAR, JDK 1.6 or operating system utilities to obtain CPU utilization for the machine. Hyperic SIGAR is preferred. If not available JDK 1.6 facilities will be used. If neither of these approaches work operating system utilities will be used (depending on the OS) to obtain CPU utilization.

Note: Hyperic SIGAR is licensed under the GPL with a FLOSS license exception, allowing it to be included with the Rio Apache License v2 distribution. If for some reason the GPL cannot be used with your distribution of Rio, remove the RIO_HOME/lib/hyperic directory.
