=head1 NAME
explain_log.pl
Feed a mysqld general logfile (created with mysqld --log) back into mysql
and collect statistics about index usage with EXPLAIN.
=head1 DISCUSSION
To optimize your indices, you have to know which ones are actually
used and what kind of queries are causing table scans. Especially
if you are generating your queries dynamically and you have a huge
amount of queries going on, this isn't easy.
Use this tool to take a look at the effects of your real life queries.
Then add indices to avoid table scans and remove those which aren't used.
=head1 USAGE
explain_log.pl [--date=YYMMDD] --host=dbhost] [--user=dbuser] [--password=dbpw] [--socket=/path/to/socket] < logfile
--date=YYMMDD select only entrys of date
-d=YYMMDD
--host=HOSTNAME db-host to ask
-h=HOSTNAME
--user=USERNAME db-user
-u=USERNAME
--password=PASSWORD password of db-user
-p=PASSWORD
--socket=SOCKET change path to the socket
-s=SOCKET
=head1 EXAMPLE
explain_log.pl --host=localhost --user=foo --password=bar < /var/lib/mysql/mobile.log
