After adding a port description to a switch, PRTG picks up the change but creates a new sensor. For example, if I change Fa1/0/12 port description to "Willy Wonka device", then in PRTG I have Fa1/0/12 FastEthernet1/0/12 and a NEW Fa1/0/12 Willy Wonka Device sensor. How can I prevent this, and keep the sensor Fa1/0/12 so that I can retain historical data? Shouldn't it simply update the information in PRTG without creating a new sensor?
