What is a valid plug-in status for a plug-in that has been added to a vSphere client?

After a plug-in is added to the vSphere Client, it can be in one of two primary operational states: Enabled or Disabled. Disabled is a valid status indicating the plug-in has been registered but is not currently active. Administrators can toggle plug-ins between Enabled and Disabled from the Plug-in Manager interface.

Unknown is not a defined plug-in status in the vSphere Client Plug-in Manager and does not appear as an assignable state for registered plug-ins.

Stopped is not a valid plug-in status in the vSphere Client; plug-ins are tracked as Enabled or Disabled, not by service-like running states.

Installed is not a recognized status label in the vSphere Client Plug-in Manager; the status field reflects operational state, not installation presence.
