Question about metrics

Help
1

I read in the documentation

metrics :link:

Enables Prometheus metrics collection; necessary before scraping metrics. Note that metrics reduce performance on really busy servers. (Our community is working on improving this. Please get involved!)

Can you provide some information what what a “really busy server” looks like. Requests / sec? How much of performance hit is there?

Should I be able to see metrics for individual reverse proxy routes? Like total request/response bytes over a given time?

Thanks
Brad

I don’t have all the answers for you, but I do know that global option probably should have a link to the docs article for metrics:

I think you’ll find some of what you’re looking for there, although questions like “what counts as a really busy server” are very hard to quantify.
