Threshold settings
Thresholds turn milliseconds into a verdict. They are compared with a host’s average latency over its last 30 pings.
- Good
- Default 50 ms. Above it a host is degraded (yellow). Up to half of it, with no loss, its quality is Excellent.
- Degraded
- Default 200 ms. Above it the quality drops from Fair to Poor.
- Critical
- Default 500 ms. Above it the quality is Bad.
Only the Good threshold changes a host’s status; the other two grade its quality and the 24-hour bar. Latency never makes a host offline: that takes three lost pings in a row, and the first reply brings it back.
Per-host thresholds
For a host whose normal latency is nothing like the rest, right-click it, choose Edit and tick Use custom latency thresholds.
fair thresholds for a distant host
A 50 ms Good threshold suits the office network, but a server on another continent will never meet it and would stay yellow for good. Give that host its own thresholds – say 250, 400 and 800 ms – and its colour shows whether that link is healthy, not just how far away it is.
