> Add self health monitoring in Mesos master
> ------------------------------------------
>
> Key: MESOS-9767
> URL: https://issues.apache.org/jira/browse/MESOS-9767
> Project: Mesos
> Issue Type: Task
> Components: master
> Affects Versions: 1.6.0
> Reporter: Gaurav Garg
> Priority: Major
> Fix For: 1.7.2
>
>
> We have seen issue where Mesos master got stuck and was not responding to
> HTTP endpoints like "/metrics/snapshot". This results in calls by the
> frameworks and metrics collector to the master to hang. Currently we emit
> 'master alive' metric using prometheus. If master hangs, this metrics is not
> published and we detect the hangs using alerts on top of this metrics. By the
> time someone would have got the alert and restarted the master process,
> 15-30mins would have passed by. This results in SLA violation by Mesos
> cluster users.
> It will be nice to implement a self health check monitoring to detect if the
> Mesos master is hung/stuck. This will help us to quickly crash the master
> process so that one of the other member of the quorum can acquire ZK
> leadership lock.
> We can use the "/master/health" endpoint for health checks.
> Health checks can be initiated in
> [src/master/main.cpp|[https://github.com/apache/mesos/blob/master/src/master/main.cpp]]
> just after the child master process is
> [spawned.|[https://github.com/apache/mesos/blob/master/src/master/main.cpp#L543]]
> We can leverage the
> [HealthChecker|[https://github.com/apache/mesos/blob/master/src/checks/health_checker.hpp]]
> for this one. One downside is that HealthChecker currently takes TaskId as
> an input which is not valid for master health check.
> We can add following flags to control the self heath checking:
> # self_monitoring_enabled: Whether self monitoring is enabled.
> # self_monitoring_consecutive_failures: After this many number of health
> failures, master is crashed.
> # self_monitoring_interval_secs: Interval at which health checks are
> performed.
