Nagios Support Forum

Hello,

I have two instances of the Nagios log server. When I first created the second instance I added it to the cluster. I look now and it looks like its on it's own cluster and there are now two separate clusters. Is there anyway I can re add the second instance to my first cluster?

I would suggest restarting both nodes. If that doesn't work, can you share the output of the following command executed from both of your Nagios Log Server nodes:

Thanks for the quick reply. Rebooting both fixed the issue. Do you know why this might have happened? I'm a little concerned that it might happen again and I have no idea what prompted this.

Thanks

The most common cause is intermittent network issues causing the instances to lose contact with each other, creating "split brain" where each instance elects itself as the master. It's hard to say for sure though.

Thanks for the help. This ticket can be closed.
