Ok, now you know that you cannot get it.

I doubt that there are databases where monitoring is unnecessary:

- if there is nothing doing in that database, that won't be a lot of statistics
  to collect

- if there is a lot going on in that database, the load will be noteworthy
  and can affect your other, necessary, databases in the same cluster, so
  you need the statistics to diagnose such problems
