NAME

       tuned-adm - command line 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 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 /usr/lib/tuned  and  the
       user  defined  profiles in subdirectories below /etc/tuned. If there are profiles with the
       same name in both places, user defined profiles have precedence.

OPTIONS

       list   List all available profiles.

       active Show current active profile.

       profile [PROFILE_NAME]
              Switches to the given profile. 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.

       verify Verifies current profile  against  system  settings.  Outputs  information  whether
              system settings match current profile or not (e.g. somebody modified a sysfs/sysctl
              value by hand). Detailed information about what is checked, what value is  set  and
              what value is expected can be found in the log.

       recommend
              Recommend  a  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   the   file
              /usr/lib/tuned/recommend.d/50-tuned.conf.  The  default  rules  recommend  profiles
              targeted to the best performance, or the balanced profile if unsure.

              The  default  rules  can  be  overridden  by  the  user  by  putting  a  file named
              recommend.conf into /etc/tuned, or by creating a file in the /etc/tuned/recommend.d
              directory.  The  file  /etc/tuned/recommend.conf is evaluated first. If no match is
              found, the files in the /etc/tuned/recommend.d directory are merged with the  files
              in  the /usr/lib/tuned/recommend.d directory (if there is a file with the same name
              in both directories, the one from /etc/tuned/recommend.d is used) and the files are
              evaluated in alphabetical order. The first matching entry is used.

       off    Unload tunings.
