Yong Qiao Wang reassigned MESOS-2080: ------------------------------------- Assignee: Yong Qiao Wang > Add master metrics for maintenance. > ----------------------------------- > > Key: MESOS-2080 > URL: https://issues.apache.org/jira/browse/MESOS-2080 > Project: Mesos > Issue Type: Task > Components: master > Reporter: Benjamin Mahler > Assignee: Yong Qiao Wang > Labels: mesosphere, twitter > > We'll need metrics in order to gain visibility into the maintenance > functionality. This will also allow operators to add alerting on these > metrics, in particular: > # Number of scheduled hosts. > # Number of active windows. > # Number of expired windows. > # Number of successful drains. > # Number of failed drains. > As an example of an alert guideline, we would want to know the number of > expired windows as a gauge to ensure that it is not growing excessively. This > allows alerting to catch when operators are not properly unscheduling > maintenance once it is complete. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
