Joseph Wu commented on MESOS-9309:
----------------------------------
You are seeing that correctly. Both the master and agent have a similar
endpoint whose only return value is {{true}}. These are purely meant to
indicate the actors are running, with no information about their state.
Metrics (i.e. {{/metrics/snapshot}}) expose more info about health.
> Master Healthcheck Only Returns True

> Key: MESOS-9309
> URL: https://issues.apache.org/jira/browse/MESOS-9309
> Project: Mesos
> Issue Type: Bug
> Reporter: Gabriel Hartmann
> Priority: Major
>
> Unless I'm reading it wrong the current [Master health
> check|https://github.com/apache/mesos/blob/master/src/master/http.cpp#L1651]
> doesn't do anything apart from return true.
> A possible candidate for a non trivial health check would be whether the
> Master has an established ZK conection.
