I see. I did it with relabeling. But this option can be in the exporter because sometimes we have no access to the MySQL's host or some another reasons. The multi-target idea can be done as well. I have 3 mariadb nodes and I forced to run one exporter per mariadb instance and I have 3 exporter instances on production that is too resource consuming.
