Yes, we do use "perf dump" but borrow the code pieces from daemonperf to parse the result, you may need to sub, max, or calc interval average, based on the counter's type. Prometheus is a MUST for such use case as it can do histogram and enable us to show percentile (like 95% commit latency) on dashboard, it is the only way to read 1000+ osd's metrics. 2017-05-19 20:22 GMT+08:00 Dan van der Ster <dan@xxxxxxxxxxxxxx>: > On Fri, May 19, 2017 at 2:18 PM, Sage Weil <sage@xxxxxxxxxxxx> wrote: >> I'm also curious how the grafana dashboards are built (I haven't used >> Grafana before).
