TUNED_ADM(8) tuned TUNED_ADM(8)
NAME
tuned-adm - commandline tool for switching between different tuning profiles
SYNOPSIS
tuned-adm [list | active | profile <profile> | off | verify | recommend]
DESCRIPTION
This command line utility allows you to switch between user definable tuning profiles. Several predefined pro‐
files 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
/usr/lib/tuned and the user defined profiles in subdirectories below /etc/tuned. If there are same profiles on
both places, user defined profiles have precedence.
OPTIONS
list List all available profiles.
active Show current active profile.
profile PROFILE
Switches to the given profilename. If none is given or no valid one is given the command gracefully
exits without performing any operation.
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.
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 overriden by user by putting the recom‐
mend.conf into /etc/tuned. The default rules recommend profiles targeted to the best performance or
balanced profile if unsure.
off Unload tunings.
FILES
