Subject Re: need help in understating solr cloud stats data

You should contribute that and spread the dev load with others :)

We need something like that at some point, it’s just no one has done it. We currently expect
you to aggregate in the monitoring layer and it’s a lot to ask IMO.

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.
