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.
       /usr/sbin/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.
