NAME
       /usr/sbin/lm-profiler - laptop mode profiler

SYNOPSIS
       /usr/sbin/lm-profiler

DESCRIPTION
       This  manual  page documents briefly the /usr/sbin/lm-profiler command.
       lm-profiler is a tool for profiling disk operations. It is  a  part  of
       laptop mode tools and is useful only in relation to rest of laptop mode
       tools. It helps you to detect programs and services that use up	system
       resources  and  that  cause disk activity, and it allows you to disable
       them when laptop mode is active.

       When you start lm-profiler, it will execute a  "profiling  run",	 which
       can  take  some time. Start lm-profiler when you are working on batter‐
       ies, preferably, because that will allow it to analyze the actual situ‐
       ation  that  it	is supposed to optimize. During the profiling run, you
       can use your system normally; however, any disk activity caused by your
       actions	will  end up in the profiler's results. When the profiling run
       is finished, you will be presented with a list of programs that deserve
       your  attention,	 either because they listen on a network (which is not
       usually useful when you are working offline)  or	 because  they	caused
       disk  activity  in a disk-spindown-unfriendly pattern. When lm-profiler
       can guess an init script that belongs to a  program,  it	 presents  you
       with  the  opportunity  to  disable the program when you are working on
       battery. It does this by placing a link to the init script in /etc/lap‐
       top-mode/batt-stop.  Any	 programs that lm-profiler cannot find an init
       script for is simply reported, so that you can stop the	program	 manu‐
       ally if you want to.

       WARNING	ABOUT  DISABLING  PROGRAMS: It may not be safe to disable some
       programs. They may be needed for proper operation of your system.  Dis‐
       able  services  only  if	 you  know what they do and why you don't need
       them.

FILES

	      lm-profiler retrieves its profiling rules from this file.
