mysql2dlf(1) convert mysql logfiles to dlf format

SYNOPSIS

mysql2dlf

DESCRIPTION

mysql2dlf converts a MySQL query log file to DLF format. Information on MySQL can be found on http://www.mysql.org/. The query log file is defined by the --log[=file] option of mysqld, or the log=file setting in MySQL configuration file.

Such a log file looks like e.g.

 /usr/sbin/mysqld, Version: 3.23.43-debug-log, started with:
 Tcp port: 3306  Unix socket: /var/run/mysqld/mysqld.sock
 Time                 Id Command    Argument

                       1 Query       SHOW VARIABLES LIKE 'pid_file'
                       1 Shutdown
 011226 21:35:59       6 Connect     [email protected] on
                       6 Init DB     nmrshiftdb
                       6 Query       SHOW VARIABLES

or

                  42401 Query       SELECT
                  bannerID,
                  banner,
                  format,
                  width,
                  height,
                  alt,
                  url
              FROM
                  banners
              WHERE
                  act = 'true'  AND (keyw = 'fullsize' OR keyw = 'global')

The generic database dlf format is described in database.xml.

EXAMPLES

To process a log as produced by MySQL:

 $ mysql2dlf < mysql-log

mysql2dlf will be rarely used on its own, but is more likely called by lr_log2report:

 $ lr_log2report mysql < /var/log/mysql-log

NOTES

The parser has been tested for query log files for MySQL 3.23.46 only.

BUGS

This converter stores all log files information in one big nested array in memory, before writing. Therefore, memory consumption is linear with the size of the log.
