@chitchat Time Period is the sampling interval:
"Time Period
The amount of time, in milliseconds, over which ping results are averaged. The default is 60000 (60 seconds, one minute). A longer Time Period will take more time for latency or loss to trigger an alarm, but it is less prone to be affected by erratic behavior in ping results.
The Time Period must be greater than twice the sum of the Probe Interval and Loss Interval, otherwise there may not be at least one completed probe."
I don't see a "Loss Latency" setting?
Play with "Packet Loss thresholds"...I seem to recall it behaving a bit like I wouldn't expect...maybe the lower threshold triggers or something. It's been a few years since I dealt with a problematic ISP.
