NAME

       tuned.conf - Tuned profile definition

DESCRIPTION

       This  man  page  documents  format  of  Tuned  2.0  profile definition files.  The profile
       definition     is     stored     in     /etc/tuned/<profile_name>/tuned.conf     or     in
       /usr/lib/tuned/<profile_name>/tuned.conf  file  where the /etc/tuned/ directory has higher
       priority.

       The tuned.conf configures the profile and it is in ini-file format.

MAIN SECTION

       The main section is called "[main]" and can contain following options:

       include=
              Includes a profile with the given name. This allows you to base a new profile on an
              already  existing  profile.  In  case  there  are conflicting parameters in the new
              profile and the base profile, the parameters from the new profile are used.

PLUGINS

       Every other section defines one plugin. The name of the section is used as  name  for  the
       plugin  and  is  used  in  logs  to  identify  the plugin. There can be only one plugin of
       particular type tuning particular device. Conflicts are by default fixed  by  merging  the
       options of both plugins together. This can be changed by "replace" option.

       Every plugin section can contain following sections:

       type=  Plugin  type.  Currently  there  are following upstream plugins: audio, bootloader,
              cpu, disk, eeepc_she, modules, mounts, net, script, scsi_host, selinux,  scheduler,
              sysctl,  sysfs,  systemd,  usb,  video,  vm.  This  list  may be incomplete. If you
              installed tuned through RPM you can list upstream plugins by the following command:
              rpm  -ql  tuned | grep 'plugins/plugin_.*.py$' Check the plugins directory returned
              by this command to see all plugins (e.g. plugins provided by 3rd party packages).

       devices=
              Comma separated list of devices which should be tuned by this plugin instance.   If
              you omit this option, all found devices will be tuned.

       replace=1
              If  there is conflict between two plugins (meaning two plugins of the same type are
              trying to configure the same devices), then the plugin defined as last replaces all
              options defined by the previously defined plugin.

       Plugins can also have plugin related options.

EXAMPLE

       [main]
       # Includes plugins defined in "included" profile.
       include=included

       # Define my_sysctl plugin
       [my_sysctl]
       type=sysctl
       # This plugin will replace any sysctl plugin defined in "included" profile
       replace=1
       # 256 KB default performs well experimentally.
       net.core.rmem_default = 262144
       net.core.wmem_default = 262144

       # Define my_script plugin
       # Both scripts (profile.sh from this profile and script from "included"
       # profile) will be run, because if there is no "replace=1" option the
       # default action is merge.
       [my_script]
       type=script
       script=${i:PROFILE_DIR}/profile.sh
