Class RestartTimeGauge

java.lang.Object

org.apache.flink.runtime.executiongraph.metrics.RestartTimeGauge

All Implemented Interfaces:

org.apache.flink.metrics.Gauge<Long>, org.apache.flink.metrics.Metric

public class RestartTimeGauge
extends Object
implements org.apache.flink.metrics.Gauge<Long>

Gauge which returns the last restarting time.

Restarting time is the time between JobStatus.RESTARTING and JobStatus.RUNNING, or a terminal state if JobStatus.RUNNING was not reached.

If the job has not yet reached either of these states, then the time is measured since reaching JobStatus.RESTARTING. If it is still the initial job execution, then the gauge will return 0.
