You first have to store all the data in Prometheus in order to be able to use a recording rule to aggregate it down. And since Prometheus's local TSDB doesn't have selective retention yet (e.g. keep detailed data only for a short time), you'd then have to have at least two Prometheus servers, one just pulling the aggregates from the other and having longer retention... So in general to me the feature request makes sense, but I'm not a Node Exporter maintainer. I'd just try filing a feature request / discussion there at https://github.com/prometheus/node_exporter/issues and see what people say. > On Wednesday, December 15, 2021 at 7:51:31 PM UTC+1 bob.c...@gmail.com > wrote: > >> Hello, >> >> I have an environment where we monitor many nodes, with many cores.
