Metrics
| Name | Type | Description | Internal Name |
|---|---|---|---|
| Number of Nodes | measurement | Number of Nodes | :numberOfNodes |
| Activations | measurement | Number of passivated nodes that have been activated. | ActivationInterceptor:activations |
| Cache Loader Loads | measurement | Number of nodes loaded through a cache loader. | CacheLoaderInterceptor:cacheLoaderLoads |
| Cache Loader Loads per Minute | measurement | Number of nodes loaded through a cache loader. | CacheLoaderInterceptor:cacheLoaderLoads |
| Cache Loader Misses | measurement | Number of unsuccessful attempts to load a node through a cache loader. | CacheLoaderInterceptor:cacheLoaderMisses |
| Cache Loader Misses per Minute | measurement | Number of unsuccessful attempts to load a node through a cache loader. | CacheLoaderInterceptor:cacheLoaderMisses |
| Cache Hits | measurement | Number of successful attribute retrievals. | CacheMgmtInterceptor:hits |
| Cache Hits per Minute | measurement | Number of successful attribute retrievals. | CacheMgmtInterceptor:hits |
| Cache Misses | measurement | Number of unsuccessful attribute retrievals. | CacheMgmtInterceptor:misses |
| Cache Misses per Minute | measurement | Number of unsuccessful attribute retrievals. | CacheMgmtInterceptor:misses |
| Hit-miss-ratio | measurement | Ratio of hits to hits and misses. A hit is a get attribute operation that results in an object being returned to the client. The retrieval may be from a cache loader if the entry isn't in the local cache. | CacheMgmtInterceptor:hitMissRatio |
| Read-write-ratio | measurement | Ratio of read operations to write operations. This is the ratio of cache hits and misses to cache stores. | CacheMgmtInterceptor:readWriteRatio |
| Cache Stores | measurement | Number of attribute store operations. | CacheMgmtInterceptor:stores |
| Cache Stores per Minute | measurement | Number of attribute store operations. | CacheMgmtInterceptor:stores |
| Cache Evictions | measurement | Number of node evictions. | CacheMgmtInterceptor:evictions |
| Cache Evictions per Minute | measurement | Number of node evictions. | CacheMgmtInterceptor:evictions |
| Number of Attributes | measurement | Number of attributes currently cached. | CacheMgmtInterceptor:numberOfAttributes |
| Number of Nodes cached | measurement | Number of nodes currently cached. | CacheMgmtInterceptor:numberOfNodes |
| Elapsed Time | measurement | Number of seconds that the cache has been running. | CacheMgmtInterceptor:elapsedTime |
| Elapsed Time per Minute | measurement | Number of seconds that the cache has been running. | CacheMgmtInterceptor:elapsedTime |
| Time since reset | measurement | Number of seconds since the cache statistics have been reset. | CacheMgmtInterceptor:timeSinceReset |
| Time since reset per Minute | measurement | Number of seconds since the cache statistics have been reset. | CacheMgmtInterceptor:timeSinceReset |
| Average Read Time | measurement | Average time in milliseconds to retrieve a cache attribute, including unsuccessful attribute retrievals. | CacheMgmtInterceptor:averageReadTime |
| Average Write Time | measurement | Average time in milliseconds to write a cache attribute. | CacheMgmtInterceptor:averageWriteTime |
| Cache Loader Stores | measurement | Number of nodes written to the cache loader. | CacheStoreInterceptor:cacheLoaderStores |
| Cache Loader Stores per Minute | measurement | Number of nodes written to the cache loader. | CacheStoreInterceptor:cacheLoaderStores |
| Invalidations | measurement | Number of cached nodes that have been invalidated. | InvalidationInterceptor:invalidations |
| Invalidations per Minute | measurement | Number of cached nodes that have been invalidated. | InvalidationInterceptor:invalidations |
| Passivations | measurement | Number of cached nodes that have been passivated. | PassivationInterceptor:passivations |
| Passivations per Minute | measurement | Number of cached nodes that have been passivated. | PassivationInterceptor:passivations |
| Tx prepares | measurement | Number of transaction prepare operations performed. | TxInterceptor:prepares |
| Tx prepares per Minute | measurement | Number of transaction prepare operations performed. | TxInterceptor:prepares |
| Tx commits | measurement | Number of transaction commit operations performed. | TxInterceptor:commits |
| Tx commits per Minute | measurement | Number of transaction commit operations performed. | TxInterceptor:commits |
| Tx rollbacks | measurement | Number of transaction rollback operations performed. | TxInterceptor:rollbacks |
| Tx rollbacks per Minute | measurement | Number of transaction rollback operations performed. | TxInterceptor:rollbacks |

| Node Locking Scheme | the node locking scheme for this cache (default is PESSIMISTIC) | no | NodeLockingScheme |
| Cache Mode | the cache mode - a cache can be configured to be either local (standalone) or clustered. If in a cluster, the cache can be configured to replicate changes, or to invalidate changes (default is LOCAL) | no | CacheMode |
| Use Repl Queue | should a replication queue be used for asynchronous replication? (default is false) | no | UseReplQueue |
| Repl Queue Interval | Time in milliseconds for elements from the replication queue to be replicated. Only used if UseReplQueue is enabled. (default is 100) | no | ReplQueueInterval |
