How can I stop or start logging of Notes client messages?

If logging is enabled and your Notes® client crashes, an automatic diagnostic collection tool collects data that includes this logging file and sends it to a mail-in application when the client restarts. You can turn this on or off.

To stop or start logging of your client messages

About this task

Your Domino® administrator designates the default setting for whether HCL Notes® logging is enabled (whether or not Notes® writes operational messages and errors to a text file on your system). Besides its being sent to a mail-in application to help diagnose crashes, the logging file is useful for diagnosing non-crash conditions that may arise.


  1. Click File > Preferences.

    Notes Basic client users: Click File > Preferences > User Preferences.

    Macintosh OS X users: Click Notes > Preferences.

  2. Click Log Settings (Notes Basic client users: click Log)..
  3. Do one of the following:
    • To stop logging for this client session, deselect Enable logging.
    • To start logging for this client session, select Enable logging.


Note: Your administrator controls the following settings:
  • Whether logging is enabled by default -- the logging setting will revert to the default whenever you restart Notes®.
  • Whether the automatic diagnostic collection tool is invisible to you, or whether you are prompted to choose whether you want to view or send the diagnostic report after a crash.
  • Whether the logging file and other data are automatically sent to HCL Support.
