             Summary: Add cache metrics for collection alias
                 Key: SOLR-9462
                 URL: https://issues.apache.org/jira/browse/SOLR-9462
             Project: Solr
          Issue Type: Improvement
      Security Level: Public (Default Security Level. Issues are Public)
          Components: JMX
    Affects Versions: 6.2
            Reporter: Michael Sun


Solr caches are major memory consumers and Solr cache metrics are critical in memory tuning. However in current implementation, only cache metrics for individual collection is available. To get the same metrics for a collection alias, which may cover tens collections, the only way is to aggregate metrics from each collection for the collection alias manually or using an external tool.

The JIRA is to provide cache metrics for a collection alias to simplify the memory tuning for collection alias.
