turboboost55	7dc100714d	metrics: add cpu counters (#26796) ... This PR adds counter metrics for the CPU system and the Geth process. Currently the only metrics available for these items are gauges. Gauges are fine when the consumer scrapes metrics data at the same interval as Geth produces new values (every 3 seconds), but it is likely that most consumers will not scrape that often. Intervals of 10, 15, or maybe even 30 seconds are probably more common. So the problem is, how does the consumer estimate what the CPU was doing in between scrapes. With a counter, it's easy ... you just subtract two successive values and divide by the time to get a nice, accurate average. But with a gauge, you can't do that. A gauge reading is an instantaneous picture of what was happening at that moment, but it gives you no idea about what was going on between scrapes. Taking an average of values is meaningless.	2 years ago

meowsbits	490b380a04	cmd/geth: allow configuring metrics HTTP server on separate endpoint (#21290) ... Exposing /debug/metrics and /debug/metrics/prometheus was dependent on --pprof, which also exposes other HTTP APIs. This change makes it possible to run the metrics server on an independent endpoint without enabling pprof.	4 years ago
