Percona and Grafana database monitoring

Hey guys!
I’ve got two machines. On 1 machine there are MariaDB and Prometheus installed. On the second machine I’ve got Grafana monitoring software installed. I monitor user statistics from the 1 machine by using Prometheus and Percona dashboards in Grafana.

On the 1 machine I have mariadb-server with a lot of different databases like

db3_selects and so on... 

My question is:

Is it possible to monitor each database separately? Like create variable with query for each particular database in Grafana and see the user statistics form only e.g. db1_users?

It seems to me that Prometheus can only recognize one server or another and cannot access particular database on server…

Thanks for any help in advance!
