     <p>The standard behaviours (<c>supervisor</c>, <c>gen_server</c>,
       and so on) send progress and error information to
       Logger. Progress reports are by default not logged, but can be
-      enabled by setting the Kernel configuration
-      parameter <c>logger_progress_reports</c> to <c>log</c>. Supervisor

+      example by using the Kernel configuration
+      parameter <c>logger_level</c>. Supervisor reports, crash reports

     <p>Prior to Erlang/OTP 21.0, supervisor, crash, and progress
       reports were only logged when the SASL application was
       running. This behaviour can, for backwards compatibility, be
       enabled by setting the Kernel configuration
-      parameter <c>logger_sasl_compatible</c> to <c>true</c>. For more
-      information, see

+      to <c>true</c>. For more information, see
       <seealso marker="sasl:error_logging">SASL Error Logging</seealso>
       in the SASL User's Guide.</p>
