INFORMATION_SCHEMA Connection-Control Tables
Table Name Description Introduced
*note 'CONNECTION_CONTROL_FAILED_LOGIN_ATTEMPTS': information-schema-connection-control-failed-login-attempts-table.
Current number 5.7.17 of consecutive failed connection attempts per account
File: manual.info.tmp, Node: information-schema-connection-control-failed-login-attempts-table, Prev: information-schema-connection-control-table-reference, Up: connection-control-information-schema-tables
This table provides information about the current number of consecutive failed connection attempts per account (user/host combination). The table was added in MySQL 5.7.17.
*note 'CONNECTION_CONTROL_FAILED_LOGIN_ATTEMPTS': information-schema-connection-control-failed-login-attempts-table. has these columns:
'USERHOST'
The user/host combination indicating an account that has failed connection attempts, in ''USER_NAME'@'HOST_NAME'' format.
'FAILED_ATTEMPTS'
The current number of consecutive failed connection attempts for the 'USERHOST' value. This counts all failed attempts, regardless of whether they were delayed. The number of attempts for which the server added a delay to its response is the difference between the 'FAILED_ATTEMPTS' value and the 'connection_control_failed_connections_threshold' system variable value.
Notes
The 'CONNECTION_CONTROL_FAILED_LOGIN_ATTEMPTS' plugin must be activated for this table to be available, and the 'CONNECTION_CONTROL' plugin must be activated or the table contents are always empty. See *note connection-control::.
The table contains rows only for accounts that have had one or more consecutive failed connection attempts without a subsequent successful attempt. When an account connects successfully, its failed-connection count is reset to zero and the server removes any row corresponding to the account.
Assigning a value to the 'connection_control_failed_connections_threshold' system variable at runtime resets all accumulated failed-connection counters to zero, which causes the table to become empty.
