.TH TUNED_ADM "8" "30 Mar 2017" "Fedora Power Management SIG" "tuned"
|
|
.SH NAME
|
|
tuned\-adm - commandline tool for switching between different tuning profiles
|
|
.SH SYNOPSIS
|
|
.B tuned\-adm
|
|
.RB [ list " | " active " | " "profile \fI[profile]\fP" " | " off " | " verify " | " recommend ]
|
|
|
|
.SH DESCRIPTION
|
|
This command line utility allows you to switch between user definable tuning
|
|
profiles. Several predefined profiles are already included. You can even
|
|
create your own profile, either based on one of the existing ones by copying
|
|
it or make a completely new one. The distribution provided profiles are stored
|
|
in subdirectories below \fI/usr/lib/tuned\fP and the user defined profiles in
|
|
subdirectories below \fI/etc/tuned\fP. If there are same profiles on both places,
|
|
user defined profiles have precedence.
|
|
|
|
.SH "OPTIONS"
|
|
|
|
.SS
|
|
.TP
|
|
.B list
|
|
List all available profiles.
|
|
|
|
.TP
|
|
.B active
|
|
Show current active profile.
|
|
|
|
.TP
|
|
.BI "profile " [PROFILE]
|
|
Switches to the given profilename. If none is given then all available profiles
|
|
are listed. If the profile given is not valid the command gracefully exits without
|
|
performing any operation.
|
|
|
|
.TP
|
|
.B verify
|
|
Verifies current profile against system settings. Outputs information whether
|
|
system settings matches current profile or not (e.g. somebody modified
|
|
sysfs/sysctl value by hand). Detailed information what is checked, what
|
|
value is set and what value is expected can be found in the log.
|
|
|
|
.TP
|
|
.B recommend
|
|
Recommend profile suitable for your system. Currently only static detection is
|
|
implemented - it decides according to data in /etc/system\-release\-cpe and
|
|
virt\-what output. The rules for autodetection are defined in recommend.conf in
|
|
profile directory. They can be overridden by user by putting the recommend.conf
|
|
into /etc/tuned. The default rules recommend profiles targeted to the best
|
|
performance or balanced profile if unsure.
|
|
|
|
.TP
|
|
.B off
|
|
