Eldewrito Nagios Plugin

Eldewrito Nagios Plugin

Monitor Your Eldewrito Server!


This is a Nagios plugin for monitoring Eldewrito servers. It queries the Eldewrito server directly and pulls the version number and current player count.

I created this to be used with LibreNMS as described in their documentation.

I wanted to be able to graph the player count in my Eldewrito server with LibreNMS. This plugin makes that possible.

The server version is output as part of the response, and the player count is appended to the response performance data.

It's a very basic implementation and could easily be extended to pull additional statistics from the server if desired.
