2012R1.0 - Occasional duplicate notification...???

[scobi]

Hi!

We seem to be getting an occasional duplicate notification since upgrading to 2012R1.0. Not every host, not every time so very difficult to replicate.

XI Host indicates it only sent 1 alert but 2 messages are received. Not related to client as the duplicate alerts are received by all the DL members (we manage notifications via Distribution Lists).

Any thoughts on this one? Not too big of a deal, we all have unlimited messaging plans...

Thanks as always!

Could you post the contact definition for the contact that is being notified twice?

[scobi]

Ummm sure! Ummm, well.. Whats the best way to get you that info?

Thanks!

[scottwilkerson]

you can either obfuscate the sensitive or send it to me in a pm or open a ticket by emailing [email protected]

Hello! Sorry I wasn't clear in my last post...

Which file do you need me to post and where is it located?

Thanks!

It may be moot, but we also get occasional duplicates on 2011 R3.2.

Which file do you need me to post and where is it located?

Code: Select all

/usr/local/nagios/etc/contacts.cfg

Also, please point out which contacts are getting duplicates

Code: Select all

define contact {                                                                
        contact_name                            Server-Alerts              
        alias                                   Server-Alerts              
        host_notification_period                Server-Alerts_notification_times                                                                           
        service_notification_period             Server-Alerts_notification_times                                                                           
        host_notification_options               d,u,r,f,s                       
        service_notification_options            w,u,c,r,f,s                     
        email                                   [email protected]                                                                          
        host_notifications_enabled              1                               
        service_notifications_enabled           1                               
        use                                     xi_contact_generic              
        }    

I was able to verify that only this contact is select in client notifications (no myself or other contacts). Also, no duplicates of the above entry in contacts.cfg...

Thanks!

Could you also post this file

Code: Select all

/usr/local/nagios/etc/contacttemplates.cfg

Additionally, can you tell me what mail method you are using in Admin-> Manage Email Settings

We have had several reports of this but it is really sporadic and would like as much information as possible to try to nail this down.

Probably TMI, but this happened again last night - if it helps, we received alerts from a couple services as follows:

Service1: Critical - Single email notification
Service1: Recovery - Single email notification
Service2: Warning - Double email notification but XI server shows 1 notification
Service2: Recovery - Single email notification

Again, not too big a deal, I'd rather have to delete a duplicate than miss a critical alert...

Thanks for looking into this!
