Benjamin Mahler created MESOS-2080:
--------------------------------------
Summary: 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
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.
