Alarms being received during a blackout for a specific VMWESXServer object
After configuring a blackout for a number of VMWESXServer objects (ESX hosts/servers), alarms are still firing for one ESX host during this blackout period.
During this time, this ESX host in question had been removed in the VMware environment. This can cause such an issue because the new ESX host will have a new object ID and (possibly) a new name. This will result in a new object within Foglight.
Ensure that no blackouts are scheduled for a particular ESX host that is scheduled to be removed from the VMware environment.
