-------------------------------------
Summary: 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
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.
