微软企业库4.1学习笔记(二十)缓存模块8 性能计数器
缓存模块包含下列计数器性能计数器解释 Cache Expiries/sec缓存项的过期比例 Cache Hit Ratio读取缓存项的比例,一次读取指的是请求的项在缓存中。 Cache Hit/sec缓存的每秒命中率Cache Misses/sec缓存的每秒丢失率,和命中率相反,就是请求项不再缓存中Cache Scavenged Item/sec
缓存清除比例Total of Cache Access Attempts从缓存中读取项的总数Total Cache Entries缓存中的项总数Total Cache Expires缓存过期项的总数Total Cache Hits缓存项的命中总数Total Cache Misses缓存项的丢失总数Total Cache Scavenged Items被清除的缓存项总数Total Updated Entries缓存被更新的总次数,更新包括添加,编辑,删除项Updated Entries/sec缓存项的更新率
