Introduction:
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.

 
Background:
This is observed in an environment where
  • most of VM's have CDM probe installed.
  • VMware API data collector is used as well.
Instructions:
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.
