> wrong way to calculate the "downtime" metric
> --------------------------------------------
>
> Key: FLINK-19009
> URL: https://issues.apache.org/jira/browse/FLINK-19009
> Project: Flink
> Issue Type: Bug
> Components: Runtime / Coordination, Runtime / Metrics
> Affects Versions: 1.7.2, 1.8.0
> Reporter: Zhinan Cheng
> Assignee: kevin liu
> Priority: Trivial
> Labels: pull-request-available
> Fix For: 1.12.0
>
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> Currently the way to calculate the Flink system metric "downtime" is not
> consistent with the description in the doc, now the downtime is actually the
> current timestamp minus the time timestamp when the job started.
>
> But Flink doc (https://flink.apache.org/gettinghelp.html) obviously describes
> the time as the current timestamp minus the timestamp when the job failed.
>
> I believe we should update the code this metric as the Flink doc shows. The
> easy way to solve this is using the current timestamp to minus the latest
> uptime timestamp.
