Nagios shows server is down - but its UP.

Post by sysmate »

I've added a new server to be monitored by my Nagios Server,
It successfully connected to the remote Server, I've set the parameters and values which I want to monitor,
But after I save the Config, Nagios will show me that the Remote Server is DOWN (although it's UP and running),
BUT Nagios will keep showing the me values of the Parameters which I've set to be monitored on the Remote Server (Disk space, CPU etc.)

How can that be?
How can it be fixed?

Please help!

Hello @sysmate

Thanks for reaching out, let's have you run through this:

Code: Select all

/usr/local/nagiosxi/scripts/reconfigure_nagios.sh
Restart the services by bouncing:

Code: Select all

systemctl restart nagios
Let us know how things look.

Thanks,
Perry

Does it show properly in the Nagios Core backend? Go here on your XI server, login with your XI credentials, and see what the host state is there:

Code: Select all
