Health badge in vCenter Server shows 0 value for vSAN objects

VMware Aria Suite


  • vRealize Operations Manager Health badge with vCenter Server shows value of 0 for vSAN objects
  • vSAN objects show values of 0 for health data within vCenter Server in Web client UI.


VMware vRealize Operations Manager 6.2.x
VMware vRealize Operations Manager 6.0.x
VMware vRealize Operations Manager 6.1.x


This issue occurs when the metrics associated with the Health badge are not available for vSAN objects.


This is expected behavior in vRealize Operations Manager 6.x.

Additional Information

  • The metric named datastore|oio|workload is not supported on vSAN datastores.
  • The metric named datastore|oio|workload depends on datastore|demand_oio, which is supported for vSAN datastores.
  • The metric named datastore|demand_oio also depends on several other metrics for vSAN datastores, one of which is not supported.
    • The metrics named devices|numberReadAveraged_average and devices|numberWriteAveraged_average are supported.
    • The metric named devices|totalLatency_average is not supported.
As a result, vRealize Operations Manager does not collect the metric named datastore|oio|workload for vSAN datastores.
