Monitoring more than one RDS instance from an EC2 instance

I can’t install the agent on an RDS instance, instead, I’ve installed it on an ec2 instance:

ubuntu @ fc-usw2-pmm-0 in ~ [22:55:55] C:1

$ sudo pmm-admin add mysql --host tr-usw2-dev0-rdm-0.chpvheywyx2p.us-west-2.rds.amazonaws.com --port 3306 --user fcdbmaster --password ***
OK, now monitoring MySQL using DSN fcdbmaster:***@tcp(tr-usw2-dev0-rdm-0.chpvheywyx2p.us-west-2.rds.amazonaws.com:3306)

ubuntu @ fc-usw2-pmm-0 in ~ [22:57:04]

$ sudo pmm-admin add mysql --host ud-usw2-dev0-rdm-0.chpvheywyx2p.us-west-2.rds.amazonaws.com --port 3306 --user fcdbmaster --password ***
Error adding MySQL: you have already the instance with this name under monitoring.

How do I change the ‘name’ so I can monitor more than one?

Check out pmm-admin add mysql --help

Usage: pmm-admin add mysql [name] [flags]

You can specify the name before or after flags.
