====clusterwide-hits====
A long representing the clustered number of cache attribute hits. May return null if the cache is not started. Also see <tt>[[#hits|hits]]</tt>.
====hits====
A long representing the number of cache attribute hits for a specific node. May return null if the cache is not started. Also see <tt>[[#clusterwide-hits|clusterwide-hits]]</tt>.
====misses====
A long representing the number of cache attribute misses for a specific node. May return null if the cache is not started. Also see <tt>[[#clusterwide-misses|clusterwide-misses]]</tt>.
====stores====
A long representing the number of put operations for this specific node. May return null if the cache is not started.  Also see <tt>[[#clusterwide-stores|clusterwide-stores]]</tt>.
====clusterwide-hit-ratio====
A read-only double representing the cluster-wide hit/miss ratio for the cache (hits/hits+misses). May return null if the cache is not started. Also see <tt>[[#read-write-ratio|read-write-ratio]]</tt>.
====hit-ratio====
A double representing the hit/miss ratio for the this node (hits/hits+misses), where the number of successful attempts is divided by the total number of attempts. Expressed in percentage. May return null if the cache is not started. Also see <tt>[[#clusterwide-read-write-ratio|clusterwide-read-write-ratio]]</tt>.
====clusterwide-read-write-ratio====
A read-only double representing the cluster-wide read/write ratio of the cache ((hits+misses)/stores). May return null if the cache is not started.
====read-write-ratio====
A double representing the read/write ratio of the cache ((hits+misses)/stores) for this specific node. May return null if the cache is not started.
====clusterwide-remove-misses====
A read-only long representing the cluster-wide number of cache attribute remove misses. May return null if the cache is not started.
====clusterwide-remove-hits====
A read-only long representing the cluster-wide number of cache attribute remove hits. May return null if the cache is not started. Also see <tt>[[#remove-hits|remove-hits]]</tt>.
====remove-hits====
A long representing the number of cache attribute remove hits for the particular node in question. Also see <tt>[[#clusterwide-remove-hits|clusterwide-remove-hits]]</tt>.
====remove-misses====
A long representing the number of cache removal misses, where the removal was attempted but the key was not found. May return null if the cache is not started.
====cache-loader-stores====
The number (as long) of cache loader store operations, for this specific node. May return null if the cache is not started.
====cache-loader-loads====
The number (as long) of cache loader load operations, for this specific node. May return null if the cache is not started.
====cache-loader-misses====
The long representing the cache loader miss operation, for this specific node. May return null if the cache is not started.
====prepares====
The long representing the number of transaction prepares, since the last reset. May return null if the cache is not started.
====commits====
The long representing the number of transaction commits, since the last reset. May return null if the cache is not started.
====rollbacks====
The long representing the number of transaction rollbacks, since the last reset. May return null if the cache is not started.
====number-of-locks-available====
An integer representing the number of exclusive locks available to this cache. Maintained by LockManager.

Overview

This article describes choices of metrics for Infinispan production monitoring.


By default, Infinispan statistics are disabled, because enabling them may have a negative impact on the performance of the subsystem. Thus, statistics should be enabled only when required. For more details on how to enable statistics, see "Enabling Cache Statistics".
