| Metrics |
| ============= |
| |
| In addition to the [usual metrics](https://gerrit-review.googlesource.com/Documentation/metrics.html#_caches) |
| exposed by caches, chronicle-map emits additional metrics that might be useful |
| to monitor the state of the cache: |
| |
| * cache/chroniclemap/percentagae_free_space_<cache-name> |
| : the amount of free space left in the cache as a percentage. |
| |
| See the [official documentation](https://javadoc.io/static/net.openhft/chronicle-map/3.20.83/net/openhft/chronicle/map/ChronicleMap.html#percentageFreeSpace--) |
| for more information. |
| |
| * cache/chroniclemap/remaining_autoresizes_<cache-name> |
| : the number of times the cache can automatically expand its capacity. |
| |
| See the [official documentation](https://javadoc.io/static/net.openhft/chronicle-map/3.20.83/net/openhft/chronicle/map/ChronicleMap.html#remainingAutoResizes--) |
| for more information. |
| |
| * cache/chroniclemap/hot_keys_capacity_<cache-name> |
| : Constant number of hot keys for the cache that can be kept in memory. |
| |
| * cache/chroniclemap/hot_keys_size_<cache-name> |
| : The number of hot keys for the cache that are currently in memory. |
