CCR might exhibit high Rx score utilization in of VMs and it is ptfrom wide.

For example Rx capacity of VM is ~80 Rx (2x CPU), host ~1066 Rx (28 CPUs 2297MHz), cpu utilization by the CDM probe is about 10% while Rx score utilization goes for ~150 (200%).   Rx/TPP is calculated so high for all VMware VMs.

This is observed in an environment where
  • most of VM's have CDM probe installed.
  • VMware API data collector is used as well.
The recommendation is to install CDM probe only for physical servers.

Swapping data sources priority should resolve Rx score utilization of VM's. Ensure to set VMware adapters higher priority.
