NSCA + Notifications

[blrg891]

Hello All!

I am running both passive checks and active checks on the the same Nagios Server. The issue is that on the Nagios dashboard I see:

Last Notification: N/A (notification 0)

For my passive checks. They are configured virtually the same as the active checks, however i am not getting notifications. I have notifications turned on at the service, host, and system level. Am I missing anything?

Thanks!!

Can you show us the config of one hosts/services that you are not getting notifications about?

Sure:

Can you show us the "linux-server" and "passive-service" templates? The config's you shared do not show the full notification definitions that are required.

Also, does this service have passive data being pushed to it? Is it in a state that should be sending you a notification?

[blrg891]

The passive service is listed above. I believe that it is second to the bottom. This is the linux server definition:

define host{
name linux-server
use generic-host
check_period 24x7
check_interval 5
retry_interval 5
max_check_attempts 3
check_command check-host-alive
notification_period 24x7
notification_interval 120
notification_options d,u,r
contact_groups admins_LOG
register 0
}

The service is passing data, the state is critical yet no notifications emails or notification indications are being listed on the dashboard.

I think I actually fixed it. I am getting updates through a port forwarded tunnel and Nagios was running host checks. It would seem that if the host check fails it doesn't care about any services running on the host and their state.

Interesting.

Thanks for the help!!!!

Correct if the host is unreachable or down the service states will not matter unless they changed before the host failed. Glad to hear this got worked out!
