I have my Nagios machine configured to send out notifications, however for some reason it seems as though if a host goes down, I sometimes don’t get a notification at all, and if they do come through its a notification saying it is back up. What would be a reason for these delayed notifications? Is there something that I’ve missed? Here is a portion of my configs:
Hosts:
notification_options d,u,r
notification_interval 120
max_check_attempts 10
retain_nonstatus_information 0
Services:
max_check_attempts 5
normal_check_interval 5
retry_check_interval 1
notification_interval 30
notification_options w,c,r
