[naemon-users] Weird issue with notification_interval (possible bug ?)

[VERVAET Frederik (ITS/IIS)]

Hi,

I noticed the following oddity the other day :

When I set the notification interval to 5  mins I see in Ninja GUI (I use naemon+merlin) the notification listed as sent but NO actual notification was sent out.

When I enable debug logs in naemon I see :

[1442523762.409221] [032.0] [pid=28500] ** Service Notification Attempt ** Host: 'machineX', Service: 'Service X', Type: NORMAL, Options: 0, Current State: 2, Last Notification: Thu Sep 17 23:02:42 2015
[1442523762.409273] [032.0] [pid=28500] SERVICE NOTIFICATION SUPPRESSED: machineX;Service X;Re-notification blocked for this problem because not enough time has passed since last notification.[1442523762.409287] [032.1] [pid=28500] Next valid notification time: Thu Sep 17 23:07:42 2015
1442523762 = Thu, 17 Sep 2015 21:02:42 GMT = Thu, 17 Sep 2015 23:02:42 (Local time)

(do note the 3rd log entry which doesn't seem to be on a new line ? this is how I see it in the logs)

As you can see last notification time in the first entry = the notification time of the current notification attempt.

It's as if Naemon somewhere starts notifying and updates a lot of internal counters/variables (including last_notification_time) and then suddenly afterwards decides to check the notification_interval value and reconsiders.

5 minutes later exactly the same in the log except the last_notification is again set to the time of the current notification and so on ... basically rendering renotifications useless.

1442524062 = Thu, 17 Sep 2015 21:07:42 GMT = Thu, 17 Sep 2015 23:07:42 (local time)
[1442524062.422325] [032.0] [pid=28500] ** Service Notification Attempt ** Host: 'hostX', Service: 'serviceX', Type: NORMAL, Options: 0, Current State: 2, Last Notification: Thu Sep 17 23:07:42 2015
[1442524062.422370] [032.0] [pid=28500] SERVICE NOTIFICATION SUPPRESSED: hostX;serviceX;Re-notification blocked for this problem because not enough time has passed since last notification.[1442524062.422382] [032.1] [pid=28500] Next valid notification time: Thu Sep 17 23:12:42 2015

As usual: as far as I can tell the config is ok.
Naemon Core 2015.c.1 (obtained from git5 repo)
Any pointed would be appreciated
