> Key: SOLR-5637
> URL: https://issues.apache.org/jira/browse/SOLR-5637
> Project: Solr
> Issue Type: New Feature

> Priority: Minor
> Attachments: SOLR-5367.patch, SOLR-5367.patch

>
> We have found it very useful to have information on the number of cache hits
> and misses for key Solr caches (filterCache, documentCache, etc.) at the
> request level.
> This is currently implemented in our codebase using custom {{SolrCache}}
> implementations.
> I am working on moving to maintaining stats in the {{SolrRequestInfo}}
> thread-local, and adding hooks in get() methods of SolrCache implementations.
> This will be glued up using the {{DebugComponent}} and can be requested using
> a "debug.cache" parameter.
