metrics world. ❑ Other tools like statsd, telegraf, etc might fit the role of exometer in your case. Use the one you’re most comfortable with. ❑ It is **very** important to be able to control the frequency which your storage receives requests. You don’t want to overload it.
**awesome** (and that’s why we’re here ;P) ❑ There are lots of resources out there on how to measure, monitor and operate it. ❑ But sadly I don’t have enough time to go in depth about it ~ Use vm_stats to gather virtual machine metrics! https://github.com/ferd/vmstats
**awesome** (and that’s why we’re here ;P) ❑ ❑ There are lots of resources out there on how to measure, monitor and operate it. ❑ ❑ But sadly I don’t have enough time to go in depth about the things the instrumentation the VM exposes ~
can “plug” measurements. ❑ Try not to spread metrics reporting “everywhere”. It’s best to separat “high level” measurements from “low level” ones. ❑ This is just the beginning. After you have this infrastructure in place, you have to start doing analysis, correlation and other math stuffs. That’s where the real *gold* is.
is **really** awesome. ❑ Another (similar) metrics collection architecture is described here: http://tech.footballaddicts.com/blog/gathering-metrics-in-elixir- applications ❑ Zed Shaw has an awesome post about statistics: ❑https://zedshaw.com/archive/programmers-need-to-learn-statistics- or-i-will-kill-them-all/
