Linux 2.6 - man page for sasl (linux section 7)

sasl(7) 			  Erlang Application Definition 			  sasl(7)

NAME
       sasl - The SASL Application

DESCRIPTION
       This  section describes the SASL (System Architecture Support Libraries) application which
       provides the following services:

	 * alarm_handler

	 * overload

	 * rb

	 * release_handler

	 * systools

       The SASL application also includes error_logger event handlers for formatting  SASL  error
       and crash reports.

   Note:
       The  SASL  application  in  OTP has nothing to do with "Simple Authentication and Security
       Layer" (RFC 4422).

ERROR LOGGER EVENT HANDLERS
       The following error logger event handlers are defined in the SASL application.

	 sasl_report_tty_h :
	   Formats and writes supervisor reports , crash reports and progress reports to stdio .

	 sasl_report_file_h :
	   Formats and writes supervisor reports , crash report and progress report to	a  single
	   file.

	 error_logger_mf_h :
	   This  error logger writes all events sent to the error logger to disk. It installs the
	   log_mf_h event handler in the error_logger process.

CONFIGURATION
       The following configuration parameters are defined for the SASL	application.  See  app(5)
       for more information about configuration parameters:

	 sasl_error_logger = Value <optional> :
	   Value is one of:

	   tty :
	     Installs sasl_report_tty_h in the error logger. This is the default option.

	   {file,FileName} :
	     Installs  sasl_report_file_h  in  the error logger. This makes all reports go to the
	     file FileName . FileName is a string.

	   false :
	     No SASL error logger handler is installed.

	 errlog_type = error | progress | all <optional> :
	   Restricts the error logging performed by  the  specified  sasl_error_logger	to  error
	   reports, progress reports, or both. Default is all .

	 error_logger_mf_dir = string() | false<optional> :
	   Specifies  in  which directory the files are stored. If this parameter is undefined or
	   false , the error_logger_mf_h is not installed.

	 error_logger_mf_maxbytes = integer() <optional> :
	   Specifies how large each individual file can be. If this parameter is  undefined,  the
	   error_logger_mf_h is not installed.

	 error_logger_mf_maxfiles = 0<integer()<256 <optional> :
	   Specifies  how  many  files	are  used. If this parameter is undefined, the error_log-
	   ger_mf_h is not installed.

	 overload_max_intensity = float() > 0 <optional> :
	   Specifies the maximum intensity for overload . Default is 0.8 .

	 overload_weight = float() > 0 <optional> :
	   Specifies the overload weight. Default is 0.1 .

	 start_prg = string() <optional> :
	   Specifies which program  should  be	used  when  restarting	the  system.  Default  is
	   $OTP_ROOT/bin/start .

	 masters = [atom()] <optional> :
	   Specifies which nodes this node uses to read/write release information. This parameter
	   is ignored if the client_directory parameter is not set.

	 client_directory = string() <optional> :
	   This parameter specifies the client directory at the master nodes.  Refer  to  Release
	   Handling  in  OTP Design Principles for more information. This parameter is ignored if
	   the masters parameter is not set.

	 static_emulator = true | false <optional> :
	   Indicates if the Erlang emulator is statically installed. A node with a static  emula-
	   tor	cannot	switch	dynamically to a new emulator as the executable files are written
	   into memory statically. This parameter is ignored if the masters and  client_directory
	   parameters are not set.

	 releases_dir = string() <optional> :
	   Indicates  where the releases directory is located. The release handler writes all its
	   files to this directory. If this parameter is not set, the  OS  environment	parameter
	   RELDIR is used. By default, this is $OTP_ROOT/releases .

	 utc_log = true | false <optional> :
	   If  set  to true , all dates in textual log outputs are displayed in Universal Coordi-
	   nated Time with the string UTC appended.
