Gregory Chanan created SOLR-8892:
------------------------------------
Summary: Allow SolrInfoMBeans to return different statistics for
/jmx vs web ui calls
Key: SOLR-8892
URL: https://issues.apache.org/jira/browse/SOLR-8892
Project: Solr
Issue Type: Bug
Components: JMX, web gui
Affects Versions: 6.0
Reporter: Gregory Chanan
Assignee: Gregory Chanan
Fix For: 6.1, trunk
Discussed this with [~markmiller]. SOLR-8869 allows us to not return field
cache entries from the SolrFieldCacheMBean. It would be nice to be a little
more flexible about this; the reason SOLR-8869 was useful was that the field
cache printing was expensive due to periodic monitoring calls to /jmx. But
turning off the field cache entry printing via SOLR-8869 also turns it off from
the web ui. It can be useful for users and admins to be able to view the cache
entries there, non-periodically, without paying a performance penalty due to
/jmx calls.
The proposal here is to allow SolrInfoMBeans to define statistics to be
returned specificially for jmx purposes and to implement a specific instance of
this for the SolrFieldCacheMBean.
