mysqldumpslow


SYNOPSIS
       mysqldumpslow [options] [log_file ...]

DESCRIPTION
       The MySQL slow query log contains information about queries that take a
       long time to execute (see Section 5.2.4, "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  s, as: Sort by rows sent or average rows went

          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

           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
