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.
Display a help message and exit.
Do not abstract all numbers to N and strings to 'S'.
Run in debug mode.
Consider only queries that match the (grep-style) pattern.
Host name of MariaDB server for *-slow.log file name. The value can contain a wildcard. The default is * (match all).
Name of server instance (if using mysql.server startup script).
Do not subtract lock time from total time.
Abstract numbers with at least N digits within names.
Reverse the sort order.
How to sort the output. The value of sort_type should be chosen from the following list:
Display only the first N queries in the output.
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
