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 state 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 Checkmk" in the online documentation
One service is created for each ESX Host System.
