A forgotten “notifies = no” (a mystery how that happened) in a poller configuration caused the poller to notify before the master (which ofcourse fails as the scripts for notification are not present on the poller). As such merlin behaved properly causing the master to not renotify. <o:p></o:p> Corrected it and sofar it seems to renotify properly. Since it was only 1 poller it would also explain why the issue came and went … (depending on which poller executed the check)<o:p></o:p> <o:p> </o:p> <div> Frederik Vervaet UNIX Monitoring (HES) | ITS/IIS <o:p></o:p> http://mon.bc<a href="http://www.proximus.be/"> <img border="0" width="140" height="30" id="_x0000_i1035" src="cid:image001.png@01D0F566.FD133C70" alt="Proximus"></a> Connect with us on: <a href="https://www.facebook.com/proximusBe"><img border="0" width="10" height="20" id="_x0000_i1034" src="cid:image002.png@01D0F566.FD133C70" alt="Proximus Facebook"></a> <a href="https://twitter.com/proximus"><img border="0" width="25" height="20" id="_x0000_i1033" src="cid:image003.png@01D0F566.FD133C70" alt="Proximus Twitter"></a> <a href="https://www.youtube.com/proximus"><img border="0" width="29" height="20" id="_x0000_i1032" src="cid:image006.png@01D0F566.FD133C70" alt="Proximus YouTube"></a> <a href="https://www.linkedin.com/company/proximus"><img border="0" width="20" height="20" id="_x0000_i1031" src="cid:image007.png@01D0F566.FD133C70" alt="Proximus LinkedIn"></a><o:p></o:p> </div> <o:p> </o:p> <div> <div style="border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm"> From: Naemon-users [mailto:naemon-users-bounces+frederik.vervaet=proximus.com@monitoring-lists.org] On Behalf Of VERVAET Frederik (ITS/IIS) Sent: Thursday 17 September 2015 23:23 To: naemon-users@monitoring-lists.org Subject: [naemon-users] Weird issue with notification_interval (possible bug ?)<o:p></o:p> </div> </div> <o:p> </o:p> Hi,<o:p></o:p> <o:p> </o:p> I noticed the following oddity the other day :<o:p></o:p> <o:p> </o:p> 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. <o:p></o:p> <o:p> </o:p> When I enable debug logs in naemon I see :<o:p></o:p> <o:p> </o:p> [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<o:p></o:p> [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<o:p></o:p> 1442523762 = Thu, 17 Sep 2015 21:02:42 GMT = Thu, 17 Sep 2015 23:02:42 (Local time)<o:p></o:p> <o:p> </o:p> (do note the 3rd log entry which doesn’t seem to be on a new line ?
