[jira] [Created] (SOLR-12834) Expose ram based cache eviction
statistics from FastLRUCache
Shalin Shekhar Mangar created SOLR-12834:
--------------------------------------------
Summary: Expose ram based cache eviction statistics from FastLRUCache
Key: SOLR-12834
URL: https://issues.apache.org/jira/browse/SOLR-12834
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: metrics
Reporter: Shalin Shekhar Mangar
Fix For: 7.6, master (8.0)
The LRUCache used for query result caches expose the following stats:
# maxRamMB
# ramBytesUsed
# evictionsRamUsage
The last one is not relevant to FastLRUCache as its behavior is to either evict by size or by heap but not both. However, the first two should be exposed by FastLRUCache as well.
