NAME

       mysql2dlf - 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
        011218 15:02:58       1 Connect     root@localhost on
                              1 Query       SHOW VARIABLES LIKE 'pid_file'
                              1 Shutdown
        011226 21:35:59       6 Connect     joe@localhost 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.
