Description
Folks,
Maxscale is running, if I stop it and manually edit the monitor file at /var/lib/maxscale/maxscale.cnf.d, enabling the detect_replication_lag, I see that MariaDBMon (and MySQLMon as well, don't create the database maxscale_schema and the table heartbeat.

Is it correct or we need to review something else?
Thanks, folks!
