System Logs specific help links no longer happen
Before the various System Logs code was condensed into a common PHP file, there was a specific help link for each type of Log.
The links are still there in help.php - search for diag_logs - like:
'diag_logs_auth.php' => 'https://doc.pfsense.org/index.php/Captive_Portal_Authentication_Logs',
'diag_logs_dhcp.php' => 'https://doc.pfsense.org/index.php/DHCP_Logs',
Of course diags_logs became status_logs and individual files like diag_logs_dhcp.php have become a URL like status_logs.php?logfile=dhcpd
So those individual help links no longer happen anywhere.
