Subject [jira] [Commented] (MESOS-2776) Master should expose metrics about oversubscribed resources
Date Wed, 03 Jun 2015 21:33:38 GMT


Yan Xu commented on MESOS-2776:

h2. Metrics

h3. Current metrics about resources
Current metrics refer to the regular resources.
To maintain backwards-compatibility we should probably keep their semantics unchanged. In
a cluster that allows oversubscribed resources these metrics become ambiguous anyways, so
we'd better create new metrics to capture of real total (regular + oversubscribed).

h3. New metrics.
I propose these metrics to be added.
(cpus|mem|disk)_revocable_total // 'Revocable' avoids distinguishing oversubscribable and
oversubscribed when referring to 'available' and 'used'.
(cpus|mem|disk)_overall_total  // (revocable + regular)

Will post proposed changes to state.json in a separate comment.

> state.json and metrics/snapshot should expose metrics on oversubscribed resources (allocated
and available).
