[jira] [Commented] (MESOS-2769) Metric for cpu scheduling latency
from all components
[ https://issues.apache.org/jira/browse/MESOS-2769?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14559972#comment-14559972 ]
Timothy Chen commented on MESOS-2769:
-------------------------------------
This is great! Is this all from cgroups, or are we adding anything specific in our containerizer? reason asking is that I wonder if we can get the same stats for docker too.
Also this will all be exposed through statistics?

> The metric will provide statistics on the scheduling latency for processes/threads in a container, i.e., statistics on the delay before application code can run. This will be the aggregate effect of the normal scheduling period, contention from other threads/processes, both in the container and on the system, and any effects from the CFS bandwidth control (if enabled) or other CPU isolation strategies.
