@jongyoul good q. I tried another stats libraries I've seen used around
(airlift), but had a hard time reconciling dependencies, so went with the
smallest footprint one + implementing the servlet myself. It looks like
metrics-core is [pretty self contained
too](https://mvnrepository.com/artifact/com.codahale.metrics/metrics-core/3.0.2)
- I'd be fine giving it a try, if folks prefer it for some reason (I'm
honestly not super up-to-speed on what's popular these days, so I'm glad to
defer this decision :-))
