Subject Re: need help in understating solr cloud stats data
Date Mon, 03 Feb 2014 15:49:05 GMT
I've had some issues monitoring Solr with the per-core mbeans and ended up writing 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.
