I’d like to get some CPU temperature metrics from the nodes in my K3s cluster. That’s the job of Prometheus’ node-exporter. I’m not using Prometheus; I’m using VictoriaMetrics. Here’s how to get it working.

I’ve got an Electric Imp Environment Tail in my office. It monitors the temperature, humidity and pressure. Currently, to display a graph, it’s using flot.js and some shonky Javascript that I wrote. It remembers samples from the last 48 hours.

The documentation for VictoriaMetrics is a bit of a mess, so here’s what worked for me.
