thanks to MySQL, the terminology here is a bit confusing. The term
"database" is used both, for the MySQL *process* and for an abstract
unit -- a set of tables -- within such a process.

The MySQL plugin collects information concerning the *process*, not the
set of tables. Therefore, connecting to the same process three times
*should* produce the same statistics three times.

In all likelihood, you can omit the "Database" option within the
"<Database />" block altogether -- "selecting" a "database" is only
necessary to satisfy some weird access configurations, afaIk.
