Interface IFailureDetector

All Known Implementing Classes:

FailureDetector

public interface IFailureDetector

Failure Detector component responsible for monitoring availability of other members in the cluster. This interface is supposed to be used internally as part cluster membership protocol. It doesn't specify that particular node is failed, but just provide information that either it is suspected or trusted at current moment of time. So it is up to cluster membership or other top level component to define when suspected member is actually failed.

Method Detail

start

void start()

Starts running failure detection algorithm. After started it begins to receive and send ping messages.

stop

void stop()

Stops running failure detection algorithm and releases occupied resources.

listen

rx.Observable<FailureDetectorEvent> listen()

Listens for results of ping checks (ALIVE/SUSPECT) done periodically by failure detector.
