VMWare ESX Host System: Maintenance State

This check queries the maintenance State of an ESX host system via the vsphere agent and returns:

OK if the ESX host has the same sate since the last service detection

CRIT if the state has changed.

The behavior can be changed by a Wato rule to force Maintenance mode or not.

See "Monitoring VMWare ESX with Check_MK" in the online documentation as well.

Discovery

On each ESX host one check is generated.
