DeadlineFailureDetector

class DeadlineFailureDetector extends FailureDetector

Implementation of failure detector using an absolute timeout of missing heartbeats to trigger unavailability.

#isAvailable will return false if there is no #heartbeat within the duration heartbeatInterval + acceptableHeartbeatPause.

Instance Constructors

  1. new DeadlineFailureDetector(config: Config, ev: EventStream)

    Constructor that reads parameters from config.

    Constructor that reads parameters from config. Expecting config properties named acceptable-heartbeat-pause.

  2. new DeadlineFailureDetector(acceptableHeartbeatPause: FiniteDuration, heartbeatInterval: FiniteDuration)(implicit clock: Clock)

    acceptableHeartbeatPause

    Duration corresponding to number of potentially lost/delayed heartbeats that will be accepted before considering it to be an anomaly.

    heartbeatInterval

    Expected heartbeat interval

    clock

    The clock, returning current time in milliseconds, but can be faked for testing purposes. It is only used for measuring intervals (duration).
