Issue/Introduction

Symptoms:
  • The CPU Contention values observed for ESXi 5.0 Update 1 and later hosts in vRealize Operations Manager (formerly known as vCenter Operations Manager) are uniformly higher than expected.
  • Examining CPU Usage and CPU Ready Time (either in vCenter Server or via esxtop) for these hosts that show high CPU Contention values indicate that neither metric is high enough to account for the high CPU Contention value.
  • CPU Contention values for ESX/ESXi 4.x hosts and ESXi 5.0 hosts appear to be accurate.


Environment

VMware vCenter Operations Manager vCenter Operations Manager (Standalone) 5.x

Resolution

This is a known issue in vRealize Operations Manager 5.0.x versions and there is no workaround.

The problem is resolved in the vRealize Operations Manager 5.6 release.
