Nagios Support Forum

Belated post. I agree; there's no reason swap should be different from other checks. The perfomance graph stands out like an extended middle finger compared to the others. I modifed the plugin code, flipping the logic and showing "used" instead of free. I also changed bytes to mb. (Bytes?!). I used the version over at the github site. The graphs don't necessarily need to be deleted, but there will be a definite break in them from old(100%) to new(0%). I hesitate to do a pull request since it changes the plugin fundamentally. PM me if you're interested.

Thanks @LaFong!

You could certainly post it to https://exchange.nagios.org/ and then link to it in this thread.
