Procurve Switch - MAC address plugged into ports

Hello, we have ProCurve and Aruba Switches. We use a monitoring product called PRTG. I would like to know if there is a way using a MIB to detect port changes, specifically, to keep track of MAC addresses plugged into ports and have alerts when changes are detected. It wouldn't need to be in exact real-time. Is there a way to do this? Thank You!
