Virtual Machine Operations Metrics for vCenter Server

VM operations metrics provide information about the actions performed on VMs. The following are some important points you must know about VM operation metrics for vCenter Server.
  • VM operations metrics is not collected for custom data centers.
  • If you edit a VM settings and do not perform any action, still it is considered as VM reconfigure operation.
  • During Revert Snapshot, VMs are powered-off, but this operation is not counted under VM Power-off metric.
  • Adding ESXi with VMs is not counted under VM Create metric.
  • Removing ESXi with VMs is not coutned under VM Remove metric.
  • VM hardstop operation is not counted under VM Power Off metric.
