java.lang.Object
- org.apache.flink.runtime.executiongraph.metrics.DownTimeGauge

All Implemented Interfaces:

Gauge<Long>, Metric
```
public class DownTimeGauge
extends Object
implements Gauge<Long>
```
A gauge that returns (in milliseconds) how long a job has not been not running any more, in case it is in a failing/recovering situation. Running jobs return naturally a value of zero.
For jobs that have never run (new not yet scheduled jobs) or jobs that have run again after failing, this gauge returns 0L, and for jobs that are not running any more, it returns -1L.
