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/store_put_failures_ : The number of errors caught when inserting entries in chronicle-map store
