High Availability (HA) capabilities with Nagios Core (4.4.6)

Postby kaushalshriyan » Mon Oct 18, 2021 12:34 pm


I am running Nagios Core 4.4.6 on CentOS Stream release 8 using thruk web interface (https://www.thruk.org) Are there any High Availability (HA) capabilities with open source Nagios Core (4.4.6) ? The reason for High Availability is to ensure that if the primary instance fails or crashes due to hardware issues secondary instance will automatically and seamlessly take over the job of monitoring without sending duplicate alert notifications.

Any suggestions or recommendations? Thanks in Advance.

Best Regards,

Linbit built out a HA solution for Nagios XI a few years back:

I don't know of anything comparable for Nagios Core that's "out of the box" and ready to go. I can think of several ways to crack that particular nut for Nagios Core, and all of them require a fairly good knowledge of how Nagios Core works.
