I am trying to setup a sensor that lets me know if a port on my router is active.
I have the oid for each port and the value returned is either 1 (there is no cable plugged in) or 2 (there is a cable plugged in).
I want to use this to alert me if someone at a remote location plugs into the spare ports on my router.
Because I use some ports and not others, some ports need to be configured so that if the status goes from 2 to 1 (someone unplugged one of my cables) it will alert.
Other ports that I am not using need to be configured so that if the status goes from 1 to 2 (someone jacked into my router) I get an alert.
I am very new to PRTG and am so far impressed with it.
