五款常用mysql slow log分析工具的比较

mysql slow log 是用来记录执行时间较长(超过long_query_time秒)的sql的一种日志工具.

启用 slow log


有两种启用方式:
1, 在my.cnf 里 通过 log-slow-queries[=file_name]

2, 在mysqld进程启动时,指定–log-slow-queries[=file_name]选项

比较的五款常用工具

mysqldumpslow, mysqlsla, myprofi, mysql-explain-slow-log, mysqllogfilter


mysqldumpslow, mysql官方提供的慢查询日志分析工具. 输出图表如下:



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).



mysqlsla, hackmysql.com推出的一款日志分析工具(该网站还维护了 mysqlreport, mysqlidxchk 等比较实用的mysql工具)



整体来说, 功能非常强大. 数据报表,非常有利于分析慢查询的原因, 包括执行频率, 数据量, 查询消耗等.



格式说明如下:

总查询次数 (queries total), 去重后的sql数量 (unique)

输出报表的内容排序(sorted by)

最重大的慢sql统计信息, 包括 平均执行时间, 等待锁时间, 结果行的总数, 扫描的行总数.



Count, sql的执行次数及占总的slow log数量的百分比.

Time, 执行时间, 包括总时间, 平均时间, 最小, 最大时间, 时间占到总慢sql时间的百分比.

95% of Time, 去除最快和最慢的sql, 覆盖率占95%的sql的执行时间.

Lock Time, 等待锁的时间.

95% of Lock , 95%的慢sql等待锁时间.

Rows sent, 结果行统计数量, 包括平均, 最小, 最大数量.
Rows examined, 扫描的行数量.

Database, 属于哪个数据库

Users, 哪个用户,IP, 占到所有用户执行的sql百分比



Query abstract, 抽象后的sql语句

Query sample, sql语句



除了以上的输出, 官方还提供了很多定制化参数, 是一款不可多得的好工具.



mysql-explain-slow-log, 德国人写的一个perl脚本.
http://www.willamowius.de/mysql-tools.html







功能上有点瑕疵, 不仅把所有的 slow log 打印到屏幕上, 而且统计也只有数量而已. 不推荐使用.

mysql-log-filter, google code上找到的一个分析工具.提供了 python 和 php 两种可执行的脚本.
http://code.google.com/p/mysql-log-filter/


功能上比官方的mysqldumpslow, 多了查询时间的统计信息(平均,最大, 累计), 其他功能都与 mysqldumpslow类似.
特色功能除了统计信息外, 还针对输出内容做了排版和格式化, 保证整体输出的简洁. 喜欢简洁报表的朋友, 推荐使用一下.

myprofi, 纯php写的一个开源分析工具.项目在 sourceforge 上.
http://myprofi.sourceforge.net/


功能上, 列出了总的慢查询次数和类型, 去重后的sql语句, 执行次数及其占总的slow log数量的百分比.
从整体输出样式来看, 比mysql-log-filter还要简洁. 省去了很多不必要的内容. 对于只想看sql语句及执行次数的用户来说, 比较推荐.


总结








































工具/功能 一般统计信息 高级统计信息 脚本 优势
mysqldumpslow 支持 不支持 perl mysql官方自带
mysqlsla 支持 支持 perl 功能强大,数据报表齐全,定制化能力强.
mysql-explain-slow-log 支持 不支持 perl 无
mysql-log-filter 支持 部分支持 python or php 不失功能的前提下,保持输出简洁
myprofi 支持 不支持 php 非常精简
