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 batteries, preferably, because that  will  allow
       it  to  analyze the actual situation 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/laptop-mode/batt-stop.  Any  programs that lm-profiler cannot find an init script
       for is simply reported, so that you can stop the program manually 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. Disable services only if you know what they do
       and why you don't need them.
