This article provides brief information and steps to resolve the issue where nodes polling with VMware credentials to get statistics have hardware health objects with incorrect status compared to the Vcenter hardware health.



Any Orion with hardware health and the VIM module



The issue is caused by "poll through vcenter".  The Vcenter has not been updated by the host machine properly.



Note: If the node is "polling through Vcenter", change it to "poll through ESX" in the Orion Virtualization Settings page.

The Hardware Health monitoring is enabled for all ESX servers automatically and you cannot enable/disable it manually. VMWare type of node can be polled for Hardware information two different ways:

A. Through vCenter
B. Directly by using CIM protocol (ESXpolling)

Polling through vCenter is using VMWare native API interface. Polling ESX server directly is using CIM protocol for get the Hardware information. 
You can use following steps to determine if node is polled through the vCenter or directly:

Go to VMWare Settings page. You can get there from Settings - Node & Group Management.


A table of all currently polled VMWare nodes will be available. This table contains column Polling Through. It is possible to hide this column.
