PingerPlot shows where along a network path a connection goes wrong. Like mtr or WinMTR, it finds every router between you and a target and keeps probing all of them, so loss, latency, jitter and a voice-quality score (MOS) build up per hop. It shows where each router is and whose network it's on, and where on the path the delay is added and loss begins.
Everything is recorded on your PC: every probe and the router that answered it, alerts, reroutes and DNS moves. A History page shows any hour of the last year: which route was slow, which router dropped probes.
Alerts judge the destination only, so a router that deprioritizes ICMP never false-alarms: a banner, a notification, a sound and a webhook (Slack, Teams, ntfy, Home Assistant). ICMP needs no admin rights; TCP, UDP and DSCP too.
