Overview

This article describes the issue when you receive following error:

Hardware polling failed: Polling of chassis (CIM_Chassis class) failed. Unable to establish session with all provided credentials  shown on all the host under Virtualization summary

Environment

NPM version 10.7 and later

Cause 

The error Polling of chassis (CIM_Chassis class) failed occurs because the ESXi hosts do not have CIM client to read CIM packages under ESX host.

 

Resolution

  • Enable the SNMP polling on this ESXi host to monitor the Hardware health:

  • Monitor the ESX host using Vcenter as VCenter has the CIM client:

Alternative Solution: Change Polling Status to go through V-Center Server instead of Direct to Host.

Change a host to poll through vCenter vs Poll ESX server directly
