What does the MySQL agent Connections dashboard represent?
解决办法
The Connections page shows graphs of some key connection metrics and three tabs with more information:
Current Connections - The MySQL process list at the time of the last sample
Failed Logins – This section shows all hosts that have made failed login attempts in the selected time range, along with error counts for all connection error types.
Users - A list of MySQL users and privileges, along with password status, current connections, and total connections in the selected time range
