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.
