| CacheLoaderInterceptor | CacheLoaderLoads | long | Number of nodes loaded through a cache loader. |
| CacheLoaderInterceptor | CacheLoaderMisses | long | Number of unsuccessful attempts to load a node through a cache loader. |
| CacheMgmtInterceptor | Hits | long | Number of successful attribute retrievals. |
| CacheMgmtInterceptor | Misses | long | Number of unsuccessful attribute retrievals. |
| CacheMgmtInterceptor | Stores | long | Number of attribute store operations. |
| CacheMgmtInterceptor | Evictions | long | Number of node evictions. |
| CacheMgmtInterceptor | NumberOfAttributes | int | Number of attributes currently cached. |
