In addition to the usual metrics exposed by caches, chronicle-map emits additional metrics that might be useful to monitor the state of the cache:
cache/chroniclemap/percentagae_free_space_ : the amount of free space left in the cache as a percentage.
See the official documentation for more information.
cache/chroniclemap/remaining_autoresizes_ : the number of times the cache can automatically expand its capacity.
See the official documentation for more information.
cache/chroniclemap/max_autoresizes_ : The maximum number of times the cache can automatically expand its capacity.
cache/chroniclemap/keys_index_size_ : The number of index keys for the cache that are currently in memory.
cache/chroniclemap/keys_index_add_latency_ : The latency of adding cache key to an index.
cache/chroniclemap/keys_index_remove_and_consume_older_than_latency_ : The latency of removing and consuming all keys older than expiration time for an index.
cache/chroniclemap/keys_index_remove_lru_key_latency_ : The latency of removing and consuming LRU key from an index.
"cache/chroniclemap/store_put_failures_ : The number of errors caught when inserting entries in chronicle-map store
