Distributed latency monitoring

Anurag Bhatia
For a while, I have been looking for a smokeping alternative for latency monitoring from different servers spread around. While smokeping has survived well over time, in 2023 it feels like an outdated package, with limited options, lacks federation etc. This post from Karan Sharma / Zerodha on “Monitoring my home network” was exciting. His setup included a telegraph agent on a local server, Prometheus to scrap data and Grafana to draw latency data.

Background I am running my own authoritative DNS servers for the last few years. In earlier stages I just used registrar-provided DNS, later moved to “Cloud provider” provided DNS and ultimately settled for running my own auth DNS. Two major requirements pushed me to self-host auth DNS: Requirement of REST API for DNS needed by the web servers to resolve Letsencrypt certbot DNS-based challenge. This allows me to have internally hosted tools with Letsencrypt issues TLS certificates instead of self-signed ones.
