---------------------------------
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.
