 .TH "LM-PROFILER" "8"
 .SH "NAME"
 .I /usr/sbin/lm-profiler
 \- laptop mode profiler
 .SH "SYNOPSIS"
 .B /usr/sbin/lm-profiler
 .SH "DESCRIPTION"
 This manual page documents briefly the
 .I /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.

 .B 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.
