This plugin logs login atempts to YOURLS. I wrote this to be used with fail2ban.

Configure the plugin by adding setting in your user/config.php

define( 'BARRE_LOG_LOGIN_FILENAME', '/path/to/filename.log' );

BARRE_LOG_LOGIN_FILENAME defines the path to where the the plugin should log authentication activities. Default value if not set is plugins/log-login/logins.log

define( 'BARRE_LOG_LOGIN_SUCCESS', false );

BARRE_LOG_LOGIN_SUCCESS (true or false) determins if successful logins should be logged or not. Default if not set is false

define( 'BARRE_LOG_LOGIN_FAILURE', true );

BARRE_LOG_LOGIN_FAILURE (true or false) determins if failed logins should be logged or not. Default if not set is true

define( 'BARRE_LOG_LOGIN_LOGOFF', false );

BARRE_LOG_LOGIN_FALSE (true or false) determins if logoffs should be logged or not. default if not set is false
