12 This man page documents format of the Tuned global configuration file.
13 The tuned-main.conf file uses the ini-file format.
14 daemon=BOOL
18 This defines whether Tuned will use daemon or not. It is boolean
19 value. It can be True or 1 if the daemon is enabled and False
20 or 0 if disabled. It is not recommended to disable daemon,
21 because many functions will not work without daemon, e.g. there
22 will be no D-Bus, no settings rollback, no hotplug support, no
23 dynamic tuning, ...
24 dynamic_tuning=BOOL
27 This defines whether the dynamic tuning is enabled. It is bool‐
28 ean value. It can be True or 1 if the dynamic tuning is enabled
29 and False or 0 if disabled. In such case only the static tuning
30 will be used. Please note if it is enabled here, it is still
31 possible to individually disable it in plugins. It is only
32 applicable if daemon is enabled.
33 sleep_interval=INT
36 Tuned daemon is periodically waken after INT seconds and checks
37 for events. By default this is set to 1 second. If you have
38 Python 2 interpreter with applied patch from Red Hat Bugzilla
39 #917709 this controls responsiveness time of Tuned to commands
40 (i.e. if you request profile switch, it may take up to 1 second
41 until Tuned reacts). Increase this number for higher respon‐
42 siveness times and more power savings (due to lower number of
43 wakeups). In case you have unpatched Python 2 interpreter, this
44 settings will have no visible effect, because the interpreter
45 will poll 20 times per second. It is only applicable if daemon
46 is enabled.
47 update_interval=INT
50 Update interval for dynamic tuning (in seconds). Tuned daemon is
51 periodically waken after INT seconds, updates its monitors, cal‐
52 culates new tuning parameters for enabled plugins and applies
53 the changes. Plugins that have disabled dynamic tuning are not
54 processed. By default the INT is set to 10 seconds. Tuned daemon
55 doesn't periodically wake if dynamic tuning is globally disabled
56 (see dynamic_tuning) or this setting set to 0. This must be
57 multiple of sleep_interval. It is only applicable if daemon is
58 enabled.
59 recommend_command=BOOL
62 This controls whether recommend functionality will be enabled or
63 not. It is boolean value. It can be True or 1 if the recommend
64 command is enabled and False or 0 if disabled. If disabled rec‐
65 ommend command will be not available in CLI, tuned will not
66 parse recommend.conf and will return one hardcoded profile (by
67 default balanced). It is only applicable if daemon is enabled.
68 By default it's set to True.
69 reapply_sysctl=BOOL
72 This controls whether to reapply sysctl settings from
73 /run/sysctl.d/*.conf, /etc/sysctl.d/*.conf and /etc/sysctl.conf
74 after Tuned sysctl settings are applied. These are locations
75 supported by sysctl --system, excluding those that contain
76 sysctl configuration files provided by system packages. So if
77 reapply_sysctl is set to True or 1, Tuned sysctl settings will
78 not override user-provided system sysctl settings. If set to
79 False or 0, Tuned sysctl settings will override system sysctl
80 settings. By default it's set to True.
81 default_instance_priority=INT
84 Default instance (unit) priority. By default it's 0. Each unit
85 has a priority which is by default preset to the INT. It can be
86 overridden in the Tuned profile by the priority option. Tuned
87 units are processed in order defined by their priorities, i.e.
88 unit with the lowest number is processed as the first.
