Hardware monitoring and VMware

Hardware monitoring is automatically enabled for VMware ESX and ESXi servers. Monitoring of VMware servers uses the CIM protocol which should be enabled by default after the installation of ESX/ESXi hosts. If installing Hardware Monitoring Agent software on a VMware host, hardware information will be detected by SAM and the check box to monitor Hardware Health of Servers will be displayed, even where hardware information might already be collected via the vCenter using the VMWare API. When this option is displayed for a VMware host, checking it will not change the hardware polling method when Poll for VMware is also selected.

If you are polling your hosts though the vCenter, you will not see the hardware option listed when you click List Resources as these nodes tend to be ICMP. This information is automatically collected by Orion, when available, through the VMware API. You will need to ensure you have the vCenter Hardware Status plug-in enabled on your V-Center for this information to be available though the VMware API, as shown below: 

Port 5989 must be opened when polling VMware servers using the CIM protocol.

If you run a scheduled Network Sonar Discovery of your existing servers, Orion will automatically collect any servers that support hardware health information the next time the scheduled discovery runs.
