You have to understand where most of the tools you are using are getting their data from - SHOW ENGINE INNODB STATUS
and SHOW GLOBAL STATUS
. This data simply is not available broken down on a database level inside MySQL.
MySQL 5.5, 5.6 and Percona Server have been doing a great job of improving the diagnostics available to you with features like performance_schema and userstats - but I don't know of any GUI/monitoring tools that are taking advantage yet.
I recommend installing Percona Server, and taking a look at table_statistics:
mysql> SELECT * FROM INFORMATION_SCHEMA.TABLE_STATISTICS
WHERE TABLE_NAME='tables_priv';
+--------------+-------------------------------+-----------+--------------+------------------------+
| TABLE_SCHEMA | TABLE_NAME | ROWS_READ | ROWS_CHANGED | ROWS_CHANGED_X_INDEXES |
+--------------+-------------------------------+-----------+--------------+------------------------+
| mysql | tables_priv | 2 | 0 | 0 |
+--------------+-------------------------------+-----------+--------------+------------------------+
