to be honest I haven't tried this out myself, I only knew this was
possible. The version I was familiar with is whats used by the dropwizard
metrics
https://github.com/dropwizard/metrics/blob/4.1-development/metrics-jvm/src/main/java/com/codahale/metrics/jvm/BufferPoolMetricSet.java
sorry you'll need to experiment with it a bit. (again, not a blocker for
this)
