I've got a switch port that is normally empty so an alert is created and sits acknowledged. What kind of check can I configure that will alert when something is plugged into the switch port?

What you could do is to create a new command using the negate plugin which will change the output of the interface status plugin to generate a Critical when something is plugged in.

Negate is used to execute other plugins, the state returned by the other plugin can be changed by the negate
plugin. For example when a check is normally considered to be in a Critical or Warning state, but the system
administrator would instead prefer to see an OK when in such a state. Understand that this will not turn any
check consistently to an OK state, but will reverse a critical to OK or an OK to critical, depending on the actual
check being run.

Check out this video for an overview on what it does.

Thanks! Sounds like what I'm looking for.
