[Java] Class ServiceRestarter

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

public class ServiceRestarter
extends AbstractPolicy

attaches to a SoftwareProcess (or anything Startable, emitting ENTITY_FAILED or other configurable sensor), and invokes restart on failure; if there is a subsequent failure within a configurable time interval, or if the restart fails, this gives up and emits ENTITY_RESTART_FAILED

Field Summary
static BasicNotificationSensor ENTITY_RESTART_FAILED

static ConfigKey FAILURE_SENSOR_TO_MONITOR

monitors this sensor, by default ENTITY_FAILED
static ConfigKey FAIL_ON_RECURRING_FAILURES_IN_THIS_DURATION

skips retry if a failure re-occurs within this time interval
static ConfigKey SET_ON_FIRE_ON_FAILURE

protected java.util.concurrent.atomic.AtomicReference lastFailureTime
