How I can do this configuration on Nagios? For example: Contact: Ticket.System@internal.inet Contact: Admin@internal.inet When a host/service goes down, I need to send notifications and repetitions normally for contact Admin, but for contact ticket.system I can only send a one notification, to be registered on my internal Ticket System. The same will be applied for warning, recovery, downtime, acknowledge, etc..
