A new release of my monitoring plugin for Nagios (and compatible) monitoring solutions is available. This version includes some added hardware monitoring for HDD, Memory & CPU Usage. There are many bug fixes which clean up a lot of the (null) and 404 errors that were occurring when run from a OSX monitoring server.
You can down load it from https://code.google.com/p/libsrvrmgrd-osx/downloads/list
To get usage instructions just run the plugin from within a terminal with no arguments. Please get stuck in and log bugs/feature requests! 🙂
