If you're talking 10K nodes and 96 cores per node, that's less than 1m timeseries; compared to the cost of the estate you are managing, it's a drop in the ocean :-) How many *other* timeseries are you storing from node_exporter?
A single timeseries eats >=4KB on all nodes I touch. Having a lot of labels (or long labels) will make it more expensive. So 1M timeseries will eat 4GB of memory. Not everyone would call that extremely cheap, especially if that's just to tell what's the cpu usage of each server. There was a PR that tried to implement scrape time recording rules, which would help here, but it didn't seem to go far - https://github.com/prometheus/prometheus/pull/10529 -- You received this message because you are subscribed to the Google Groups "Prometheus Users" group.
