We have 5 groups and enabled on all groups monitoring agent. We use Ops Manager 1.6.2.251.

All metrics get collected and are available in a nice graph. CPU Time is not available on all groups. Our VMs are OpenStack based with RHEL7.

Howto debug that? Found nothing relevant to CPU time in /opt/mongodb/mms/logs

You must have munin-node installed, configured and reachable (on port 4949) by the MMS agents in order for CPU and other system data to be collected. This is all covered in the documentation.

  • Since then, the documentation you linked added the note As of Automation Agent 2.7.0, hardware monitoring using munin-node is deprecated.. Nov 29, 2017 at 15:23

    this was answered over 2 years ago, and the product has moved on (a lot) since then (as have I - I have not used it for roughly that long), so unless you are running something really old I don't think this would apply to a current installation
