brooklyn.policy.ha
[Java] Class MemberFailureDetectionPolicy

java.lang.Object
  brooklyn.policy.basic.AbstractEntityAdjunct
      brooklyn.policy.basic.AbstractPolicy
          brooklyn.policy.ha.MemberFailureDetectionPolicy

public class MemberFailureDetectionPolicy
extends AbstractPolicy

Detects when members of a group have failed/recovered, and emits ENTITY_FAILED or ENTITY_RECOVERED accordingly. This policy should be associated with a group to monitor its members: 

 group.addPolicy(new MemberFailureDetectionPolicy(...));
Basic "failure" is defined as the service being "running" but isUp having flipped from true to false. These criteria can be further configured using "onlyReportIfPreviouslyUp" and "useServiceStateRunning".
