MySQL Enterprise Monitor 8.0 Release Notes
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.
