[jira] [Commented] (SOLR-9898) Documentation for metrics collection and /admin/metrics

    [ https://issues.apache.org/jira/browse/SOLR-9898?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15892436#comment-15892436 ] 

Otis Gospodnetic commented on SOLR-9898:
----------------------------------------

While I love all the new metrics you are adding, I think metrics should be treated like code/features in terms of how backwards compatibility/deprecation is handled.  Otherwise, on upgrade, people's monitoring breaks.... and monitoring is kind of important... :)

Note: Looks like recent metrics changes broke/changed previously-existing MBeans...
