   micrometer.io looks interesting.
   
   Have I understood micrometer correctly? The Fuseki counters/stats/... implement in the micrometer framework and then a choice of adapter makes that available to the specific package.
   
   micrometer-core is about 0.5 Mbytes so not huge itself but it has dependencies (oddly, slf4j does not seem to isn't a dependency, log4j2 and logback are) - what might the size impact be?
   
   Given the need to provide a choice of implementations, we have to have a way to allow choice but also work out of the box. Fuseki/full as a war file, and to some extent the server jar, are sealed so "some assembly required". Fuseki/main might be more tractable although again, the combined jar (the easy way to run it).
   
   @ajs6f  - it used `org.pcollections` - is that like Dexx?
