I’ve written about installing and using Graphite and it’s a really great tool for measuring lots of kinds of metrics. Most of the guides online don’t touch on the security aspects of this setup, and there was at least one thing that I thought should be worth writing about.
How are we measuring
Metrics we gather from our applications have the current characteristics / requirements:
- We want to gather lots of data over time.
- Any single data-point isn’t significant on its own. Only in aggregate.
- Measuring is important, but not if it slows down our application in any way.
