Greg Mann commented on MESOS-3022:
----------------------------------
Since this is a long outstanding issue related exclusively to the
SchedulerDriver, I'm going to close the ticket. If we add more metrics for the
scheduler API, we should do so with the intention of accommodating both the
unversioned and the V1 scheduler APIs.
> export additional metrics from scheduler driver

> Key: MESOS-3022
> URL: https://issues.apache.org/jira/browse/MESOS-3022
> Project: Mesos
> Issue Type: Improvement
> Reporter: David Robinson
> Assignee: James Wang
> Priority: Minor
>
> The scheduler driver only exports the metrics below, but ideally it would
> export its version and a count of messages by message type.
> {code}
> $ curl -s localhost:20902/metrics/snapshot | python -m json.tool
> {
> "scheduler/event_queue_dispatches": 0,
> "scheduler/event_queue_messages": 0,
> "system/cpus_total": 24,
> "system/load_15min": 0.49,
> "system/load_1min": 0.36,
> "system/load_5min": 0.46,
> "system/mem_free_bytes": 269713408,
> "system/mem_total_bytes": 33529266176
> }
> {code}
> The scheduler driver version could be used during troubleshooting to identify
> frameworks that are using an old, potentially backwards incompatible,
> scheduler driver (eg, a framework hasn't been restarted after a Mesos deploy,
> so it still links against an old incompatible libmesos).
> A count of messages by message type would help identify a problem w/ a
> specific feature, eg task reconciliation.
