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 |
