Hi, I have a switch with about 250 interfaces. I can see that the switch uplink ports were very utilized a month ago, and I would like to pin point the server interface that caused this load.

what is the best way for me to do that with PRTG?

I would recommend either: - a report of all the 250 sensors of the specific timeframe, then you can browse through the graphs visually. - if it was "enough" to raise a visible peak in the graph, you could just open the device in PRTG, click on the 30 days or other interval and check those graphs for suspicious peaks. - if you have unusual detection active, you could search the logs in the timeframe of the incident for the specific interface: Logs -> Status Changes -> Unusual and then filter for the timeframe. (not sure since which version this is available)

Another source of information is the Similar Sensor Analysis. Make sure this is enabled. It will go through already recorded historic data, and then show sensors with similar value-"curves" in the same time on the "Overview"-Page of a sensor.
