The most common DRAMA logging system is GitLogger(3). Normally the application initialises GitLogger(), which tells DRAMA to use GitLogger(3) to write log messages.
This command just inquires if there is a logging system - through it is not impossible that this could be confused by an errant logging system (which does not use a clientData item correctly).
