=== Cache metrics
Auto-configuration will enable the instrumentation of all available ``Cache``s on startup
with a metric named `cache`. The prefix can be customized by using the
`management.metrics.cache.cache-metric-name` property. Cache instrumentation is specific
to each cache library, refer to https://micrometer.io/docs[the micrometer documentation]
for more details.
The following cache libraries are supported:
* Caffeine
* EhCache 2
* Hazelcast
* Any compliant JCache (JSR-107) implementation
Metrics will also be tagged by the name of the `CacheManager` computed based on the bean
name.
NOTE: Only caches that are available on startup are bound to the registry. For caches
created on-the-fly or programmatically after the startup phase, an explicit registration
is required. A `CacheMetricsRegistrar` bean is made available to make that process easier.
