Overview

Each Infinispan individual cache exposes a number of performance metrics, and the cache container managing those caches aggregate some of those metrics at container level. These metrics are described below.

Average Read, Write and Remove Time

These metrics represent an individual cache read/write/remove operation average time response time, in milliseconds. For reads, the value includes hits and misses. May return null if the cache is not started. Maintained as a long. The metric always maintains the last value, even after the cache become idle. In order to reset it, you must reset underlying caches statistics, individually, with :reset-statistics.

The values for these metrics are aggregated at container level, for all caches managed by this container. They are calculated by averaging values for of the corresponding values for individual cache managed by this container.

Resetting Statistics

it is possible to reset statistics for an individual cache using the :reset-statistics CLI operation, applied to the management model node corresponding to that cache.

aliases

The list of aliases for this cache container. Type: String array.

hits

The number of cache attribute hits. Type: Long. TODO c34rsz. This is an additive value for all caches managed by this container.

misses

The number of cache attribute misses. Type: Long. TODO c34rsz. This is an additive value for all caches managed by this container.

stores

The number of cache attribute put operations (writes). Type: Long. TODO c34rsz. This is an additive value for all caches managed by this container.
