Notification stops working

[vy3734]

My notification stops sending out emails for some hosts and services while the rest are still working fine. Notification setting is turned on for all hosts and services. Don't know why it stops working on some hosts and services. Can anyone help on this?

We'll need a bit more information to start debugging. One good place to start is to use the Notifications option on the left-hand pane of the Home screen. This will tell you if the notifications are actually being generated or not. If you see all of the notifications you expect then we'll have to troubleshoot why your mailer isn't getting the notifications to the end target. Often times it's an SMTP limit imposed by your mail service provider.

If you're not seeing the notifications you expect it's an issue internal to Nagios, and my first guess would be a misunderstanding of the max_check_attempts directive:

max_check_attempts: This directive is used to define the number of times that Nagios will retry the host check command if it returns any state other than an OK state. Setting this value to 1 will cause Nagios to generate an alert without retrying the host check. Note: If you do not want to check the status of the host, you must still set this to a minimum value of 1. To bypass the host check, just leave the check_command option blank.
