Dynamic cache counters

Use the PMI data for Dynamic Cache to monitor the behavior and performance of the dynamic cache service. For information on the functions and usages of dynamic cache, refer to Using the dynamic cache service to improve performance.

Use the DynaCache MBean to access the related data and display it under Dynamic Cache in TPV.

Name	Key	Description	Granularity	Type	Level
Max in memory cache size	cacheModule.maxInMemoryCacheSize	Maximum number of in-memory cache entries	Per server	CountStatistic	Low
In memory cache size	cacheModule.inMemoryCacheSize	Current number of in-memory cache entries	Per server	CountStatistic	Low
Timeouts	cacheModule.totalTimeoutInvalidations	Aggregate of template timeouts and disk timeouts	Per server	CountStatistic	Low
Hits in memory	cacheModule.template.hitsInMemory	Requests for this cacheable object served from memory	Per template	CountStatistic	Low
Hits on disk	cacheModule.template.hitsOnDisk	Requests for this cacheable object served from disk	Per template	CountStatistic	Low
Explicit invalidations	cacheModule.template.explicitInvalidations	Total explicit invalidation issued for this template	Per template	CountStatistic	Low
LRU invalidations	cacheModule.template.lruInvalidations	Cache entries evicted from memory by a Least Recently Used algorithm. These entries are passivated to disk if disk overflow is enabled.	Per template	CountStatistic	Low
Timeouts	cacheModule.template.timeoutInvalidations	Cache entries evicted from memory or disk, or both, because their timeout has expired	Per template	CountStatistic	Low
Entries	cacheModule.template.entries	Current number of cache entries created from this template. Refers to the per-template equivalent of totalCacheSize.	Per template	CountStatistic	Low
Misses	cacheModule.template.misses	Requests for this cacheable object that were not found in the cache	Per template	CountStatistic	Low
Client requests	cacheModule.template.requestsFromClient	Requests for this cacheable object generated by applications running on the appserver	Per template	CountStatistic	Low
Distributed requests	cacheModule.template.requestsFromJVM	Requests for this cacheable object generated by cooperating caches in this cluster	Per template	CountStatistic	Low
Explicit invalidations (memory)	cacheModule.template.explicitInvalidationsFromMemory	Explicit invalidations resulting in an entry being removed from memory	Per template	CountStatistic	Low
Explicit invalidations (disk)	cacheModule.template.explicitInvalidationsFromDisk	Explicit invalidations resulting in an entry being removed from disk	Per template	CountStatistic	Low
Explicit invalidations (no op)	cacheModule.template.explicitInvalidationsNoOp	Explicit invalidations received for this template where no corresponding entry exists	Per template	CountStatistic	Low
Local explicit invalidations	cacheModule.template.explicitInvalidationsLocal	Explicit invalidations generated locally, either programmatically or by a cache policy	Per template	CountStatistic	Low
Remote explicit invalidations	cacheModule.template.explicitInvalidationsRemote	Explicit invalidations received from a cooperating JVM in this cluster	Per template	CountStatistic	Low
Remote creations	cacheModule.template.remoteCreations	Entries received from cooperating dynamic caches	Per template	CountStatistic	Low
