Vcenter Disk Usage

[martin.schwarz]

The vSphere special agent only retrieves information on hosts, VMs, datastores, etc.,
not the information on disk usage or processes etc. inside the (PhotonOS-/Linux-based) vCenter appliance. You could install the normal Linux agent inside the vCSA appliance, but …

See previous discussion e.g. here:

Install checkmk agent on vCenter?

If you install the normal Linux agent (rpm) on a vCenter appliance, you will get the usual Linux agent checks i.e. mostly information related to the operating system itself. If you are curious about the internal function of the appliance, you can do this, sure. But IMO this information is not really relevant on an appliance. I’m not going to modify the swap size or tune some kernel parameters on that system, anyway. Rather treat it as a blackbox and check it using only the supplier’s tools.
