Stefan Egli commented on SLING-5965:
------------------------------------
[~chetanm], I can go via JMX yes - however would be good to release
commons.metrics 1.0.2 (see [mail on
list|http://markmail.org/message/gm6bxavnxumhz4pj] as in 1.0.0 metrics are not
exposed as JMX.
> Metrics and a Health-Check for Scheduler to detect long-running Quartz-Jobs

>
> Sling Scheduler jobs (aka Quartz-Jobs) should typically be fast running jobs.
> They are served from a thread-pool and should occupy that thread only for a
> short amount of time.
> If there are 'misbehaving' quartz-jobs that run for a very long time, they
> start to occupy threads from that thread-pool, thus have an influence on the
> performance of other scheduled/quartz-jobs.
> We should have metrics (using
> [sling.commons.metrics|https://sling.apache.org/documentation/bundles/metrics.html])
> that provide information about internas of Sling Scheduler, such as average,
> max etc duration of scheduled jobs, as well as how many jobs are currently
> running and since when was the oldest job running.
> Based on this, a Health-Check can monitor the 'oldest job running' metric and
> flag {{critical}} when eg the oldest job is older than {{60'000ms}}
> (configurable, default).
