Use this page as a reference for properties of MBean cache statistics.
You can use the Performance Monitoring Infrastructure (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 Task overview: Using the dynamic cache service to improve performance .
MBean attributes | Description |
CacheHits | The total number of cache hits. |
CacheLruRemoves | The number of memory-based least recently used (LRU) evictions. These correspond to the number of objects that are evicted from the memory cache, based on the LRU policy. |
CacheMisses | The total number of cache misses. |
CacheRemoves | The total number of cache removes. |
DependencyIdsOnDisk | Metric that captures the total number of dependency identifiers that are currently on disk. |
DependencyIdsBufferedForDisk | Metric that captures the number of dependency identifiers that are buffered in memory for the disk. |
DependencyIdsOffloadedToDisk | Metric that captures the number of dependency IDs that are off-loaded to disk since the server startup. This is a cumulative count. |
DependencyIdBasedInvalidationsFromDisk | Metric that captures the number of dependency ID-based invalidations that have occurred since server startup. |
DiskCacheSizeInMB | The total size of data objects in MB. |
ExplicitInvalidationsFromMemory | Metric that captures the number of explicit invalidations that result in an entry being removed from memory. |
ExplicitInvalidationsFromDisk | Metric that captures the number of explicit invalidations that result in an entry being removed from disk. |
ExplicitInvalidationsLocal | Metric that captures the number of explicit invalidations that are generated locally. |
ExplicitInvalidationRemote | Metric that captures the number of explicit invalidations that generate from a cooperating Java virtual machine (JVM) in the cluster. |
ObjectsOnDisk | Metric that captures the number of cache entries that are currently on disk. |
PendingRemovalFromDisk | Metric that captures the number of objects that have been invalidated due to an explicit event, such as an invalidation, or some implicit event, such as a timeout or eviction policy, but are yet to be removed from disk. |
TimeoutInvalidationFromDisk | Metric that captures the number of timeout invalidations that result in an entry being removed from disk. |
TimeoutInvalidationsFromMemory | Metric that captures the number of timeout invalidations that result in an entry being removed from memory. |
TemplatesOnDisk | Metric that captures the number of templates on disk. |
