I have a database with a lot of users, all of them with full read privileges on all the tables but not all the users are reading all the tables. I want to have each user having as little privileges as they need. Each user belongs to a different large legacy application for which auditing the code is not feasible.

How do I go about obtaining this information?

This would have a considerable impact on your system, but you could enable the MySQL General Query Log by running the following:

SET GLOBAL general_log = 'ON';

The default setting for the logs will output to a file that can be identified by running this:

SHOW GLOBAL VARIABLES WHERE Variable_name = 'general_log_file';

Otherwise, you can change the setting to log in a table with the line below, and then you would be able to run queries on the table mysql.general_log

SET GLOBAL log_output = 'TABLE';

  • What tool do I use then to parse the logs and build the graph?

    One possible tool is your eyeballs. Another may be pt-query-digest.
