I'll alter the plugin within the next days so that it'll be useable for 0.20.x or higher as well. We're still using 0.18.3 here since it's quite stable. Thanks for the example.

We just launched a new website exchange.nagios.org. It would be great if you could add your plugins to the new site. Thanks! It looks like you have some good plugins for Nagios.
