  • :evictions - When a cache entry is removed.
  • :expirations - When a cache entry is expired.
  • :hits - When a key is looked up in cache and found.
  • :misses - When a key is looked up in cache but not found.
  • :updates - When an existing cache entry is or updated.
  • :writes - When a cache entry is inserted or overwritten.

Metadata
