Subject Re: need help in understating solr cloud stats data
Date Mon, 03 Feb 2014 16:25:14 GMT
The code I wrote is currently a bit of an ugly hack so I'm a bit reluctant to share it and
there's some legal concerns with open-sourcing code within my company. That being said, I
wouldn't mind rewriting it on my own time. Where can I find a starter kit for contributors
with coding guidelines and the like? Spruced up some I'd be OK with submitting a patch.

a custom "request handler" that gets loaded then registers itself as an mbean. When called
it polls all the per-core mbeans then adds or averages them where appropriate before returning
the requested value. I'm not sure if there's a better way to get jvm-wide stats via jmx but
it is *a* way to get it done.
