java.lang.Object | +--com.sleepycat.db.DbMpoolStat
The DbMpoolStat object is used to return memory pool statistics.
| Field Summary | |
|  int | st_allocNumber of page allocations. | 
|  int | st_alloc_bucketsNumber of hash buckets checked during allocation. | 
|  int | st_alloc_max_bucketsMaximum number of hash buckets checked during an allocation. | 
|  int | st_alloc_max_pagesMaximum number of pages checked during an allocation. | 
|  int | st_alloc_pagesNumber of pages checked during allocation. | 
|  int | st_bytesBytes of cache (total cache size is st_gbytes + st_bytes). | 
|  int | st_cache_hitRequested pages found in the cache. | 
|  int | st_cache_missRequested pages not found in the cache. | 
|  int | st_gbytesGigabytes of cache (total cache size is st_gbytes + st_bytes). | 
|  int | st_hash_bucketsNumber of hash buckets in buffer hash table. | 
|  int | st_hash_examinedTotal number of hash elements traversed during hash table lookups. | 
|  int | st_hash_longestThe longest chain ever encountered in buffer hash table lookups. | 
|  int | st_hash_max_waitThe maximum number of times any hash bucket lock was waited for by a thread of control. | 
|  int | st_hash_nowaitThe number of times that a thread of control was able to obtain a hash bucket lock without waiting. | 
|  int | st_hash_searchesTotal number of buffer hash table lookups. | 
|  int | st_hash_waitThe number of times that a thread of control was forced to wait before obtaining a hash bucket lock. | 
|  int | st_mapRequested pages mapped into the process' address space (there is no available information about whether or not this request caused disk I/O, although examining the application page fault rate may be helpful). | 
|  int | st_ncacheNumber of caches. | 
|  int | st_page_cleanClean pages currently in the cache. | 
|  int | st_page_createPages created in the cache. | 
|  int | st_page_dirtyDirty pages currently in the cache. | 
|  int | st_page_inPages read into the cache. | 
|  int | st_page_outPages written from the cache to the backing file. | 
|  int | st_page_trickleDirty pages written using the DbEnv.memoryPoolTricklemethod. | 
|  int | st_pagesPages in the cache. | 
|  int | st_region_nowaitThe number of times that a thread of control was able to obtain a region lock without waiting. | 
|  int | st_region_waitThe number of times that a thread of control was forced to wait before obtaining a region lock. | 
|  int | st_regsizeIndividual cache size. | 
|  int | st_ro_evictClean pages forced from the cache. | 
|  int | st_rw_evictDirty pages forced from the cache. |
