Using MySQL query logs to debug authentication issues

I recently installed LogAnalyzer, and after the install completed I noticed that nothing was being displayed in the web interface. I figured I fat fingered something, but needed a way to verify this. Luckily for me I was using MySQL, so I enabled MySQL query logging and low and behold I proved my hypothesis:

120212 12:09:33     6 Connect   rsyslog@localhost on
                    6 Init DB   Access denied for user 'rsyslog'@'%' to database 'Syslog'

To fix this I logged into the database and changed the password for the rsyslog user:

$ mysql -u root -h localhost –password
mysql> use Syslog


Everything began working once the application could authenticate, and I was able to start playing around with LogAnalyzer. Noting this here in case I fat finger another password in the future. :)
