Install nrpe on XenServer

If you are using nagios in your hosting environment and need to install nrpe on your XenServer servers, here’s a good way to do it.
I’m using XenServer 6.1 (latest version).

First, install the epel repo and disable it by default:

Next, install nrpe:

If you get an error like this:

Then disable the Citrix repo by changing ‘enabled=1′ to ‘enabled=0′ in /etc/yum.repos.d/Citrix.repo and try again.

 

Set it to start automagically on boot:

Install Nagios plugins – these are some that we use..

Next, add the following line to the iptables config just before the REJECT line at the bottom:
(Found here: /etc/sysconfig/iptables – this will allow your nagios server to connect to your XenServer)

Next, restart the firewall:

Start nrpe:

Edit the nrpe config file (/etc/nagios/nrpe.cfg) and take a look at the check commands at the bottom. If you have any questions about how to get it set up further feel free to comment on this post!

  1. Yes! Man, you are on a roll! I’ve been missing my alerts, and this post came right on time. Thank you so much for these no-muss, no fuss directions. I’m pretty new to server maintenance and I swear some of so-called “Easy to Follow” instructions that I find are written for rocket scientists.

  2. Thanks for that. A very detailed and thorough explanation. I will give it a try using your guide and if I have any issues I wil post here for your help if you don’t mind. Very kind of you to offer to help anyone having trouble.
