I've configured hosts in the cluster and YARN containers to use cgroups. I see that proper files are getting created in the /sys/fs/cgroup/ directory, but I can't see any diagrams in cgroups related section of Cloudera Manager. When I look at these metrics in CM API , they are all empty for all roles. I don't see any relevant errors in the agent's logs. Is there some configuration I need to enable to get CM agents to collect these metrics?
