NAME

       /etc/laptop-mode/lm-profiler.conf - Configuration file for lm-profiler, a profiler for laptop-mode-tools.

DESCRIPTION

       This  manual  page documents the options that can be set in the /etc/laptop-mode/lm-profiler.conf configuration file.  For a description of
       what lm-profiler does, see the lm-profiler(8) manpage.

SETTINGS

       The syntax of options is OPTION=value.

       The following settings are available in lm-profiler.conf:

       VERBOSE_OUTPUT
		 Set this to 1 if you want to see a lot of output when you run lm-profiler, and 0 if you don't want  this.  Useful  for  debugging
		 purposes. (Currently does nothing.)

       PROFILE_RUN_LENGTH
		 The length of a profiling run, in seconds. This should be a while, so that lm-profiler can gather enough information. The default
		 is 10 minutes (600 seconds).

       ACTIVITY_INTERVAL_MIN

       ACTIVITY_INTERVAL_MAX
		 The behaviour that you want to avoid when you have your hard drive spun down, is disk accesses that are  spread  out  over  time,
		 because  your	hard  drive will have to spin up for each access. lm-profiler detects when applications perform disk accesses that
		 are at least some time apart (otherwise they can be considered part of the same access) but not TOO far apart (otherwise they are
		 no problem). These settings configure what lm-profiler considers "at least some time apart" and "too far apart", respectively, in
		 seconds.

       RECOMMEND_DEFAULT_SERVICES

       DEFAULT_SERVICES
		 If RECOMMEND_DEFAULT_SERVICES is set to 1 (enabled), then lm-profiler will always suggest turning  off  the  services	listed	in
		 DEFAULT_SERVICES (separated by spaces).

       IGNORE_PROGRAMS
		 Programs listed in this option, separated by spaces, will be ignored for disk activity profiling. The default settings (which can
		 be referenced as $DEF_IGNORE_PROGRAMS) include common utility programs and all programs used by lm-profiler itself.

       RECOMMEND_NETWORK_SERVICES
		 When this option is enabled (value 1), lm-profiler will detect any services that are listening on network ports, and it will sug-
		 gest that you disable them.

       IGNORE_NETWORK_SERVICES
		 Services  listed  in  this  configuration option (separated by spaces) are not suggested as a network service by lm-profiler. The
		 default values can be accessed as $DEF_IGNORE_NETWORK_SERVICES.

DESCRIPTION

       The profiler package provides a simple Tcl source code profiler.  It is a function-level profiler; that is, it collects only function-level
       information, not the more detailed line-level information.  It operates by redefining the Tcl proc command.  Profiling is initiated via the
       ::profiler::init command.

COMMANDS

       ::profiler::init
	      Initiate	profiling.   All procedures created after this command is called will be profiled.  To profile an entire application, this
	      command must be called before any other commands.

       ::profiler::dump pattern
	      Dump profiling information for the all functions matching pattern.  If no pattern is specified, information for all  functions  will
	      be  returned.  The result is a list of key/value pairs that maps function names to information about that function.  The information
	      about each function is in turn a list of key/value pairs.  The keys used and their values are:

	      totalCalls
		     The total number of times functionName was called.

	      callerDist
		     A list of key/value pairs mapping each calling function that called functionName to the number of times it  called  function-
		     Name.

	      compileTime
		     The runtime, in clock clicks, of functionName the first time that it was called.

	      totalRuntime
		     The sum of the runtimes of all calls of functionName.

	      averageRuntime
		     Average runtime of functionName.

	      descendantTime
		     Sum of the time spent in descendants of functionName.

	      averageDescendantTime
		     Average time spent in descendants of functionName.

       ::profiler::print ?pattern?
	      Print profiling information for all functions matching pattern.  If no pattern is specified, information about all functions will be
	      displayed.  The return result is a human readable display of the profiling information.

       ::profiler::reset ?pattern?
	      Reset profiling information for all functions matching pattern.  If no pattern is specified, information will be reset for all func-
	      tions.

       ::profiler::suspend ?pattern?
	      Suspend profiling for all functions matching pattern.  If no pattern is specified, profiling will be suspended for all functions. It
	      stops gathering profiling information after this command is issued. However, it does not erase any profiling  information  that  has
	      been gathered previously.  Use resume command to re-enable profiling.

       ::profiler::resume ?pattern?
	      Resume profiling for all functions matching pattern.  If no pattern is specified, profiling will be resumed for all functions.  This
	      command should be invoked after suspending the profiler in the code.

       ::profiler::sortFunctions key
	      Return a list of functions sorted by a particular profiling statistic.  Supported values for key are: calls, exclusiveTime, compile-
	      Time, nonCompileTime, totalRuntime, avgExclusiveTime, and avgRuntime.  The return result is a list of lists, where each sublist con-
	      sists of a function name and the value of key for that function.

BUGS, IDEAS, FEEDBACK
       This document, and the package it describes, will undoubtedly contain bugs and other problems.  Please report such in the category profiler
       of the Tcllib SF Trackers [http://sourceforge.net/tracker/?group_id=12883].  Please also report any ideas for enhancements you may have for
       either package and/or documentation.
