> 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.
