SmokePing without SmokePing: latency smoke graphs with Telegraf, InfluxDB and Grafana

Grafana Smokeping dashboard over 24 hours with simulated data: a summary table of six targets, then the latency graph of upstream.example.net. The median sits at about 9 ms all day except in the evening, when it rises to 20 to 36 ms around 21:00 with tall grey smoke up to 80 ms; the packet-loss strip below turns yellow, orange and red during that time and shows a short black mark at 04:05.
24 hours of simulated data based on the measured baselines: evening congestion on the upstream path and a short nightly reconnect at 04:05.

SmokePing’s grey smoke shows at a glance whether a link is merely slow or unstable. If Telegraf, InfluxDB and Grafana already run, you don’t need SmokePing itself: Telegraf’s ping input sends the same 20-ping bursts and computes percentiles, and a few Grafana overrides draw the smoke. The probe, the dashboard, and two traps that cost me half of my samples.
