Devmon if_col

Hi All.

I´ve been using devmon for some time to monitor cisco switches. Thanks to devmon I noticed I had collisions on one of the interface on my core switch, after fixing the port speed and duplex I want to reset the counters for that interface. I ran "clear counters gigabi... ifnr" and "clear controllers ethernet-controller.." but devmon is still showing me old counters on the if_col page. How do I reset the counter ??
