In practice the documentation is incorrect. While technically the metric
_would_ emit -1 if the job is in a failed/finished state, the reality is
that at this point the metric is unregistered and no longer updated,
since the owning component (the jobmanager) is shutting down.
I can't think of a workaround for this problem at the moment.

Hi all, i'm monitoring Flink jobs using prometheus.
I have been trying to use the metrics
flink_jobmanager_job_uptime/downtime in order to create an alert, that
fires when one of this values emits -1 since the doc says this is the
behavior of the metric when the job gets to a completed state.
The thing is that i have tested the behavior when one of my job fails
and the mentioned metrics never emit something different than zero.
Finally the metric disappears after the job has failed.
Am i missing something or is this the expected behavior ?
