MySQL 8.3 Release Notes
This table provides information about the current number of consecutive failed connection attempts per account (user/host combination).
CONNECTION_CONTROL_FAILED_LOGIN_ATTEMPTS has these columns:
-
USERHOSTThe user/host combination indicating an account that has failed connection attempts, in
'format.user_name'@'host_name' -
FAILED_ATTEMPTSThe current number of consecutive failed connection attempts for the
USERHOSTvalue. 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 theFAILED_ATTEMPTSvalue and theconnection_control_failed_connections_thresholdsystem variable value.
Notes
-
The
CONNECTION_CONTROL_FAILED_LOGIN_ATTEMPTSplugin must be activated for this table to be available, and theCONNECTION_CONTROLplugin must be activated or the table contents are always empty. See Section 8.4.2, “The Connection-Control Plugins”. -
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_thresholdsystem variable at runtime resets all accumulated failed-connection counters to zero, which causes the table to become empty.
