MYSQLDUMPSLOW(1)             MySQL Database System            MYSQLDUMPSLOW(1)

NAME
       mysqldumpslow - Summarize slow query log files
SYNOPSIS
       mysqldumpslow [options] [log_file ...]
DESCRIPTION
       The MySQL slow query log contains information about queries that take a
       long time to execute (see Section 5.2.5, "The Slow Query Log").
       mysqldumpslow parses MySQL slow query log files and prints a summary of
       their contents.
       Normally, mysqldumpslow groups queries that are similar except for the
       particular values of number and string data values. It "abstracts"
       these values to N and 'S' when displaying summary output. The -a and -n
       options can be used to modify value abstracting behavior.
       Invoke mysqldumpslow like this:
           shell> mysqldumpslow [options] [log_file ...]
       mysqldumpslow supports the following options.
       o   --help
           Display a help message and exit.
       o   -a
           Do not abstract all numbers to N and strings to 'S'.
       o   --debug, -d
           Run in debug mode.
       o   -g pattern
           Consider only queries that match the (grep-style) pattern.
       o   -h host_name
           Host name of MySQL server for *-slow.log file name. The value can
           contain a wildcare. The default is * (match all).
       o   -i name
           Name of server instance (if using mysql.server startup script).
       o   -l
           Do not subtract lock time from total time.
       o   -n N
           Abstract numbers with at least N digits within names.
       o   -r
           Reverse the sort order.
       o   -s sort_type
           How to sort the output. The value of sort_type should be chosen
           from the following list:
           o   t, at: Sort by query time or average query time
           o   l, al: Sort by lock time or average lock time
           o   s, as: Sort by rows sent or average rows sent
           o   c: Sort by count
       o   -t N
           Display only the first N queries in the output.
       o   --verbose, -v
           Verbose mode. Print more information about what the program does.
       Example of usage:
           shell> mysqldumpslow
           Reading mysql slow query log from /usr/local/mysql/data/mysqld51-apple-slow.log
           Count: 1  Time=4.32s (4s)  Lock=0.00s (0s)  Rows=0.0 (0), root[root]@localhost
            insert into t2 select * from t1
           Count: 3  Time=2.53s (7s)  Lock=0.00s (0s)  Rows=0.0 (0), root[root]@localhost
            insert into t2 select * from t1 limit N
           Count: 3  Time=2.13s (6s)  Lock=0.00s (0s)  Rows=0.0 (0), root[root]@localhost
            insert into t1 select * from t1
