Hi again, Sorry for the delay - work, you know...
The ordinary check_mysql is in my environment configured at host level using variables: vars.mysql_database = "mysql" vars.mysql_username = "nagios" vars.mysql_password = "xxxxxxxx" vars.mysql_port = 3306 But I don't define my own check command as you do. I use the predefined one in the template library which follows Icinga 2 (https://github.com/Icinga/icinga2/blob/master/doc/10-icinga-template-library.md). And it seems to work fine. The Percona plugins on the other hand are much, much easier to set up using the file /etc/nagios/mysql.cnf which you create on the host that performs the check: [client] user = nagios password = xxxxxxxx Hope this helps you a bit further...

It is not obvious from your setup... Thank you!
