I am evaluating PRTG right now and have an error that seems to be intermittent. Almost every Cisco router/switch will show the following error from time to time. The alert goes away for a while, but returns. I have verified that each device is getting time from our NTP master and each device is set to the correct time. Is there a known bug with the SNTP sensor, or is there a way to globally adjust the settings of a sensor or to globally disable a sensor? Thanks.
