How to install a plugin from github?

[reincarne]

Hi,
I'm wondering how to install plugins from github?
I used to work with simple command scripts but not with more complicated plugins.
For example this plugin:
https://github.com/pyr/check-graphite

First of all I guess I need to install ruby on my server.
Now where do I put the files? I assume I need to create a new folder inside the lib folder, move there the plugin files.
Then create a new command in Nagios which is using the check_graphite.rb file as a command.

Am I right or there is something else to do?

Also what what is the best ruby version to work on red had with nagiosxi?

Thanks in advance.

You are correct in thinking that first you need ruby, then you need to install this as a gem(or so I would think), the plugin however should be added to /usr/local/nagios/libexec, and finally yes you need a command for your services in nagios to use. Honestly, I would just look into "yum install ruby" or something similar to get the rpm version of ruby installed from redhat repos.
