Class CPUMonitorEventDetector

java.lang.Object
  network.detectors.EventDetector
      network.detectors.CPUMonitorEventDetector

All Implemented Interfaces:

java.lang.Runnable, java.io.Serializable

public class CPUMonitorEventDetector

extends EventDetector

implements java.io.Serializable

The CPUMonitorEvent Detector generates a list of all currently running processes and respective statistics on a monitored host, using the UNIX `ps' command. This detector may be triggered by calling its generateEvent method.
