Mark Miller commented on SOLR-7458:
-----------------------------------
What do we know about the expense of this? For a monitoring tool that might be
pounding JMX on a dozen large collections every 30-60 seconds, I'm a little
worried about iterating through all the files and making server calls for each
one.
