You can run the mysql command "show processlist" to see what queries are being processed at any given time, but that probably won't achieve what you're hoping for as this won’t show the whole SQL text.
Here are the steps to dump sql into a file for analysis.
Turn on the SQL Logging and go to the general_log_file location.
Do your queries (on any db). Grep or otherwise examine /var/run/mysqld/mysqld.log
Then don't forget to disable the general_log parameter to OFF.
or the performance will plummet and your disk will fill!
