--------------------------------------
Summary: thermos observer should fetch disk usage metrics from
Mesos
Key: AURORA-1917
URL: https://issues.apache.org/jira/browse/AURORA-1917
Project: Aurora
Issue Type: Task
Components: Observer
Reporter: David Robinson
At Twitter we've seen the observer web UI take up to 1.5 minutes to respond to
requests. Further investigation revealed that the observer was CPU bound while
calculating disk usage of a container with 500k files. Mesos already calculates
task's disk usage, the Observer could fetch the metrics from Mesos instead of
calculating them itself.
