void	probeBooted(ProbeStatus status) A probe has just booted
void	probeFailure(ProbeFailedException exception) A probe has failed
void	probeProcessStateChange(ProbePhase probePhase) The probe process has changed state.
void	probeResult(ProbePhase phase, ProbeStatus status) Report a probe outcome
void	probeTimedOut(ProbePhase currentPhase, Probe probe, ProbeStatus lastStatus, long currentTime) A probe has timed out

Method Detail

probeProcessStateChange

void probeProcessStateChange(ProbePhase probePhase)

The probe process has changed state.

Parameters:

probePhase - the new process phrase

probeResult

void probeResult(ProbePhase phase,
               ProbeStatus status)

Report a probe outcome

Parameters:

phase - the current phase of probing

status - the probe status

probeFailure

void probeFailure(ProbeFailedException exception)

A probe has failed

probeBooted

void probeBooted(ProbeStatus status)

A probe has just booted

Parameters:

status - probe status

commence

boolean commence(String name,
               String description)

unregister

void unregister()

heartbeat

void heartbeat(ProbeStatus status)

A heartbeat event should be raised

Parameters:

status - the probe status

probeTimedOut

void probeTimedOut(ProbePhase currentPhase,
                 Probe probe,
                 ProbeStatus lastStatus,
                 long currentTime)

A probe has timed out

Parameters:

currentPhase - the current execution phase

probe - the probe that timed out

lastStatus - the last status that was successfully received -which is implicitly not the status of the timed out probe

currentTime - the current time

liveProbeCycleCompleted

void liveProbeCycleCompleted()

Event to say that the live probe cycle completed so the entire system can be considered functional.
