Preconfigured vSphere Alarms
vCenter Server provides a list of default alarms, which monitor the operations of vSphere inventory objects.
You must only set up actions for these alarms.
Some alarms are stateless. vCenter Server does not keep data on stateless alarms, does not compute, or
display their status. Stateless alarms cannot be acknowledged or reset. Stateless alarms are indicated by an
asterisk next to their name.
