Agreed. The firmware has nothing to do in the schema. And to make things worse the most used timeseries database, Prometheus, is missing. 10M is not particularly high. If your company run prometheus/nodeexporter monitoring 1000 servers, you should be in that order of magnitude (expect 1000 to 10000 metrics per machine).
