tuned-main.conf - Tuned global configuration file
/etc/tuned/tuned-main.conf
This man page documents format of the Tuned global configuration
file. The tuned-main.conf file uses the ini-file format.
- daemon=BOOL
- This defines whether Tuned will use daemon or not. It is boolean value. It
can be True or 1 if the daemon is enabled and False
or 0 if disabled. It is not recommended to disable daemon, because
many functions will not work without daemon, e.g. there will be no D-Bus,
no settings rollback, no hotplug support, no dynamic tuning, ...
- dynamic_tuning=BOOL
- This defines whether the dynamic tuning is enabled. It is boolean value.
It can be True or 1 if the dynamic tuning is enabled and
False or 0 if disabled. In such case only the static tuning
will be used. Please note if it is enabled here, it is still possible to
individually disable it in plugins. It is only applicable if daemon
is enabled.
- sleep_interval=INT
- Tuned daemon is periodically waken after INT seconds and checks for
events. By default this is set to 1 second. If you have Python 2
interpreter with applied patch from Red Hat Bugzilla #917709 this controls
responsiveness time of Tuned to commands (i.e. if you request profile
switch, it may take up to 1 second until Tuned reacts). Increase this
number for higher responsiveness times and more power savings (due to
lower number of wakeups). In case you have unpatched Python 2 interpreter,
this settings will have no visible effect, because the interpreter will
poll 20 times per second. It is only applicable if daemon is
enabled.
- update_interval=INT
- Update interval for dynamic tuning (in seconds). Tuned daemon is
periodically waken after INT seconds, updates its monitors,
calculates new tuning parameters for enabled plugins and applies the
changes. Plugins that have disabled dynamic tuning are not processed. By
default the INT is set to 10 seconds. Tuned daemon doesn't
periodically wake if dynamic tuning is globally disabled (see
dynamic_tuning) or this setting set to 0. This must be multiple of
sleep_interval. It is only applicable if daemon is enabled.
- recommend_command=BOOL
- This controls whether recommend functionality will be enabled or not. It
is boolean value. It can be True or 1 if the recommend
command is enabled and False or 0 if disabled. If disabled
recommend command will be not available in CLI, tuned will not
parse recommend.conf and will return one hardcoded profile (by
default balanced). It is only applicable if daemon is
enabled. By default it's set to True.
- reapply_sysctl=BOOL
- This controls whether to reapply sysctl settings from the
/etc/sysctl.conf, /etc/sysctl.d/*.conf,
/usr/lib/sysctl.d/*.conf, /usr/local/lib/sysctl.d/*.conf,
/lib/sysctl.d/*.conf, /run/sysctl.d/*.conf, i.e. all
locations supported by sysctl --system after Tuned sysctl settings
are applied, i.e. if set to True or 1 Tuned sysctl settings
will not override system sysctl settings. If set to False or
0 Tuned sysctl settings will override system sysctl settings. By
default it's set to True.
- default_instance_priority=INT
- Default instance (unit) priority. By default it's 0. Each unit has
a priority which is by default preset to the INT. It can be
overridden in the Tuned profile by the priority option. Tuned units
are processed in order defined by their priorities, i.e. unit with the
lowest number is processed as the first.
no_daemon = 0
