Zhu Zhu commented on FLINK-30558:
---------------------------------
Yes this is a problem, especially considering that {{fullRestarts}} is
deprecated and is supposed to be replaced with {{numRestarts}}.
Thanks for reporting this issue and volunteering to fix it. [~xiasun]
I have assigned you the ticket.

> Project: Flink
> Issue Type: Bug
> Components: Runtime / Metrics
> Affects Versions: 1.17.0
> Reporter: xingbe
> Assignee: xingbe
> Priority: Major
> Fix For: 1.17.0

>
> The method SchedulerBase#registerJobMetrics register metrics 'numRestarts'
> and 'fullRestarts' with the same metric object, as discussed in FLINK-30246,
> that will result in the loss of the metric 'numRestarts'.
> {code:java}
> metrics.gauge(MetricNames.NUM_RESTARTS, numberOfRestarts);
> metrics.gauge(MetricNames.FULL_RESTARTS, numberOfRestarts);{code}
> I have verified this problem via rest api /jobs/:jobid/metrics, and the
> response shows below, we can find that the metric 'numRestarts' is missing.
