Display "Failed login attempts" in Logman
If the Joomla system plugin "System User Log" is enabled, a log is kept of failed login attempts, showing date, IP address, failure message and username attempting to login.
For any site, particularly a membership based site, it would be helpful to see who is incorrectly trying to login and perhaps to see what they are doing wrong.
This info is a challenge to access however as it requires downloading the error.php from the hosting files under httpsdocs/logs.
Can this be pulled into Logman?
