Yong Qiao Wang commented on MESOS-3022: --------------------------------------- [~bmahler], Per my investigation, following messages by type should be added into the scheduler metrics: {code} process::metrics::Counter messages_registered_framework; process::metrics::Counter messages_reregistered_framework; process::metrics::Counter messages_resource_offers; process::metrics::Counter messages_rescind_offer; process::metrics::Counter messages_status_update; process::metrics::Counter messages_executor_to_framework; process::metrics::Counter messages_slave_lost; process::metrics::Counter messages_framework_error_messages; {code} If something is missed, could you let me know? > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
