tuned-main.conf: Tuned global configuration file
NAMEtuned-main.conf - Tuned global configuration file
DESCRIPTIONThis man page documents format of the Tuned global configuration file. The tuned-main.conf file uses the ini-file format.
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, ...
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.
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 intepreter will poll 20 times per second. It is only
applicable if daemon is enabled.
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.
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.
This controls whether to reapply sysctl settings from the /etc/sysctl.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 defualt it's set to True.
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.
