慢查询日志分析工具-mysqldumpslow

2017-04-27  本文已影响6人  温东

mysql官方提供的慢查询日志分析工具.主要功能是,

统计不同慢sql的出现次数(Count),执行最长时间(Time),累计总耗费时间(Time),等待锁的时间(Lock),发送给客户端的行总数(Rows),扫描的行总数(Rows),用户以及sql语句本身(抽象了一下格式,比如limit 1, 20用limit N,N表示).

常用的参数:

-s排序选项:c:访问计数l:锁定时间r:返回记录t:查询时间al:平均锁定时间ar:平均返回记录数at:平均查询时间 -t只显示top n条查询
