Class CPUProcessCongestionMonitor

java.lang.Object

org.mobicents.commons.congestion.CPUProcessCongestionMonitor

All Implemented Interfaces:

CongestionMonitor

public class CPUProcessCongestionMonitor
extends java.lang.Object
implements CongestionMonitor

This Congestion Monitor monitors whether or not the CPU Process usage has crossed the cpuThreshold and notifies its listeners. If it has then it monitors if the CPU Process usage has reduced and come under the backToNormalCPUThreshold and notifies its listeners
