解析binlog工具百家争鸣，最常用的是mysqlbinlog，各有千秋，对于DBA，唯手熟尔罢了
然而，有工具的地方就有江湖，故本文无意争论工具属优属劣，，免得引起不成熟的争端

仅介绍pt-query-digest其实也是能用来解析Binlog，友好、可读性强、便于快速诊断故障

如果直接：
[root@ld88 mysqldata]# pt-query-digest --type binlog mysql-bin88.000189
将无法解析，需先做如下转换
[root@ld88 mysqldata]# mysqlbinlog mysql-bin88.000189 > mysql-bin88.000189.sql

看两个例子，以下为了排版，对输出做了大量裁减-_-!

㈠指定时间窗口

[root@ld88 mysqldata]# pt-query-digest --type binlog --since "2013-11-06 20:55:00" --until "2013-11-06 21:00:00" mysql-bin88.000189.sql
