Jan Høydahl commented on SOLR-14752:
------------------------------------
Have not tested the monitoring things yet. Is it only the mntr endpoint that
changes when prometheus is enabled? Have you found documentation in ZK project
that the MNTR output format changes in this way, or could it be a bug?
Anyway, it should be possible to do replace all the parseInt() calls with a
custom method that is more tolerant and also can handle floats. Would you like
to attempt a PR?
