MySQL Enterprise Monitor 3.3.9 Manual

16.3.2 Adding Multiple MySQL Instances

The Add Bulk MySQL Instances tabs are identical to those used to add a single instance, with the exception of the Instance Address field, which is replaced by the Connection Endpoints field in the bulk version. To add multiple MySQL instances, add the comma-separated list of MySQL addresses to the Connection Endpoints field in the format of Hostname:PortNumber.

To add the instances successfully, you must ensure the user credentials, encryption settings, and so on, are identical across all instances added.
