How to enable/disable debug logging for Plesk backend utilities on Windows

Question

This article describes the debug logging for the Plesk backend utilities (i.e. utilities within the
%plesk_bin%
folder). It is also applicable for troubleshooting of the Plesk integration with a third-party application (like mail or DNS server). For all other cases, it is sufficient to enable debug logging described in this KB article.

Answer

To enable debug logging for the Plesk backend utilities:

1. Log into the server via RDP.

2. Create (if it does not exist) the
HKLMSOFTWAREWow6432NodePLESKPSA ConfigConfigDebug
registry entry of type
DWORD . Set its value to 1. You can use the
regedit.exe
utility or run the following command in the command-line:

   C:> REG ADD "HKLMSOFTWAREWow6432NodePLESKPSA ConfigConfig" /v Debug /t REG_DWORD /d 1 /f

3. Debug information is start logging immediately in the Event Viewer > Applications and Services Logs > Plesk and into the
%plesk_dir%adminlogsplesklog_debugYYYYmmdd.log
file, where YYYYmmdd represents current day of the year.

Note: It is strongly recommended to switch off debug logging once it is not necessary as it may slow down your server performance and consume a lot of disk space.

To disable logging for the Plesk backend utilities:

Set the
HKLMSOFTWAREPLESKPSA ConfigConfigDebug
registry entry value to 0 or just remove it. Command-line examples below:

• To check registry entry:

  C:> REG QUERY "HKLMSOFTWAREWow6432NodePLESKPSA ConfigConfig" /v Debug

• To switch off:

  C:> REG ADD "HKLMSOFTWAREWow6432NodePLESKPSA ConfigConfig" /v Debug /t REG_DWORD /d 0 /f

• To delete entry:

  C:> REG DELETE "HKLMSOFTWAREWow6432NodePLESKPSA ConfigConfig" /v Debug /f
