Fan Status (VMware) service

The Fan Status (VMware) service monitors the status and speed (RPM) of the fans on ESXi servers. SolarWinds N-central uses the Common Information Model (CIM) services and ports for monitoring.

If your ESX/ESXi server is operating on either Dell or HP hardware, it is strongly recommended that you install the Dell or HP Offline Bundle before the Windows probe discovers the ESX/ESXi server.

To access information on the fans on your ESXi server, use a browser to access the following URL:
