And I thank them for it. I was using the TICK stack a few years ago and the switch to TIG (Telegraf, InfluDB, and Grafana) has been a breath of fresh air.
Telegraf and InfluxDB are solid, but Chronograf was behind Grafana in usability and features.
Kapacitor was pretty rough. The language it used was hard to write, the docs were barebones, somewhat confusing, and sometimes inaccurate. When I switched off of Kapacitor, the CPU usage on the server dropped significantly too. So I'm guessing Kapacitor wasn't too CPU friendly either.
Prometheus is not just the db itself, it’s the ecosystem around it. You’ve got service-discovery, alertmanager and basically every application in existence having a /metrics endpoint and some pre-made Grafana dashboard.
