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 While smokeping has survived well over time, in 2023 it feels like an outdated package, with limited options, lacks federation etc.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. I explored doing the same but in a distr...| Personal blog of Anurag Bhatia

You can install the dashboard from the G...| Chris Bergerons Tech Blog
