Oh, current could get version informations from http endpoint after MESOS-1841
is applied.

> 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: Yong Qiao 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.
