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.
