As a side note, I’m into storage performance and the node-exporter data is absolutely spot on. I performed storage benchmarks with FIO and the metrics matched the loads and reported os metrics (iostat) perfectly.
I actually made a Grafana dashboard[0] for it, but haven’t used this in a while myself.
