NAME


mysqldumpslow - Summarize slow query log files

SYNOPSIS


mysqldumpslow [options] [log_file ...]

DESCRIPTION


The MariaDB slow query log contains information about queries that take a long time to
execute. mysqldumpslow parses MariaDB 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.

· --help

Display a help message and exit.

· -a

Do not abstract all numbers to N and strings to ´S´.

· --debug, -d

Run in debug mode.

· -g pattern

Consider only queries that match the (grep-style) pattern.

· -h host_name

Host name of MariaDB server for *-slow.log file name. The value can contain a
wildcard. The default is * (match all).

· -i name

Name of server instance (if using mysql.server startup script).

· -l

Do not subtract lock time from total time.

· -n N

Abstract numbers with at least N digits within names.

· -r

Reverse the sort order.

· -s sort_type

How to sort the output. The value of sort_type should be chosen from the following
list:

· t, at: Sort by query time or average query time

· l, al: Sort by lock time or average lock time

· s, as: Sort by rows sent or average rows sent

· c: Sort by count

· -t N

Display only the first N queries in the output.

· --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
