Method Details

getLocalCacheStatistics

@Deprecated
List<CacheStatistics> getLocalCacheStatistics()

Deprecated.

since 7.5 Use ManagedCache.getStatistics()

Retrieve all the cache statistics for locally held caches. In a clustered setting, distributed caches will report only on the locally held portion of the cache.

Returns:

list of cache statistics sorted by their localised CacheStatistics.getNiceName().

getLocalCacheStatistics

@Deprecated
CacheStatistics getLocalCacheStatistics(String cacheName)

Deprecated.

since 7.5 Use ManagedCache.getStatistics()

Retrieve the cache statistics for one locally held cache. In a clustered setting, distributed caches will report only on the locally held portion of the cache.

Returns:

list of cache statistics sorted by their localised CacheStatistics.getNiceName().

getCapabilities

Set<CacheStatisticsCapability> getCapabilities()

Returns the set of optional capabilities supported by this implementation

Since:

5.5

getCacheStatisticFilter

default Predicate<com.atlassian.cache.CacheStatisticsKey> getCacheStatisticFilter(String cacheName)

For a given cache, returns a predicate that can be used to filter which CacheStatisticsKeys are appropriate for that cache. For example, it may not be appropriate to measure the heap size for a given cache, so CacheStatisticsKey.HEAP_SIZE will not pass the predicate.

Since:

7.5
