Nagios Support Forum

Hi Team,

We are looking to have the drives of our worker servers monitored on the main Nagios server.

However, when performing a test check it throws the following error:

connect to host <hostname> port 5666: No route to host.

Also, can you please suggest what is the best plugin to monitor the mailq on a server?

Thank you.

To add to this, I have found that the NRPE service is disabled on both servers.

The initial set up was done by another colleague who doesn't work here anymore so I'm not sure if this was setup intentionally.

Will enabling the NRPE service effect the performance of the worker in anyway? Will this impact the checks on the primary server?

Having NRPE on the worker shouldn't impact it in any meaningful way as long as the plugins it runs are well behaved.

The official Nagios plugins include a check_mailq plugin:

Thanks for your reply. You can close this case.
