MySQL Enterprise Monitor 8.0 Release Notes
The MySQL user: For Agents to
report the status of a MySQL server, they connect to a MySQL
user with privileges to read required data on that server:
SHOW DATABASES, REPLICATION
CLIENT, SUPER,
CREATE, and SELECT. If you
already have such a user on a MySQL server, specify its
credentials when installing the Agent for that server. For
details about this account, see
Section 6.2, “Creating MySQL User Accounts for the Monitor Agent”.
