High Availability (HA) capabilities with Nagios Core (4.4.2)

[kaushalshriyan]

Hi,

Are there any High Availability (HA) capabilities with open source Nagios Core (4.4.2) ? 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,

Kaushal

A lot of folks have done hot/cold setups with DRBD, both with Nagios Core and Nagios XI.

For centrally managing the configuration, I know of options for Puppet, Chef, and Ansible:
