16 This command line utility allows you to switch between user definable
17 tuning profiles. Several predefined profiles are already included. You
18 can even create your own profile, either based on one of the existing
19 ones by copying it or make a completely new one. The distribution pro‐
20 vided profiles are stored in subdirectories below /usr/lib/tuned and
21 the user defined profiles in subdirectories below /etc/tuned. If there
22 are profiles with the same name in both places, user defined profiles
23 have precedence.
24
27 list List all available profiles.
28 profiles List all available profiles.
31 plugins List all available plugins.
34 -v, --verbose List plugin's configuration options and
37 their hints.
38 active Show current active profile.
41 profile [PROFILE_NAME]...
44 Switches to the given profile. If more than one profile is
45 given, the profiles are merged (in case of conflicting settings,
46 the setting from the last profile is used) and the resulting
47 profile is applied. If no profile is given, then all available
48 profiles are listed. If the profile given is not valid, the com‐
49 mand gracefully exits without performing any operation.
50 profile_info [PROFILE_NAME]...
53 Show information/description of given profile or current profile
54 if no profile is specified.
55 verify [-i | --ignore-missing]
58 Verifies current profile against system settings. Outputs infor‐
59 mation whether system settings match current profile or not
60 (e.g. somebody modified a sysfs/sysctl value by hand). Detailed
61 information about what is checked, what value is set and what
62 value is expected can be found in the log. With the -i or --ig‐
63 nore-missing it does not treat missing tuning (tuning unsup‐
64 ported by the platform) as error.
65 recommend
68 Recommend a profile suitable for your system. Currently only
69 static detection is implemented - it decides according to data
70 in /etc/system-release-cpe and virt-what output. The rules for
71 autodetection are defined in the file /usr/lib/tuned/recom‐
72 mend.d/50-tuned.conf. The default rules recommend profiles tar‐
73 geted to the best performance, or the balanced profile if un‐
74 sure.
75 The default rules can be overridden by the user by putting a
77 file named recommend.conf into /etc/tuned, or by creating a file
78 in the /etc/tuned/recommend.d directory. The file
79 /etc/tuned/recommend.conf is evaluated first. If no match is
80 found, the files in the /etc/tuned/recommend.d directory are
81 merged with the files in the /usr/lib/tuned/recommend.d direc‐
82 tory (if there is a file with the same name in both directories,
83 the one from /etc/tuned/recommend.d is used) and the files are
84 evaluated in alphabetical order. The first matching entry is
85 used.
86 auto_profile
89 Enable automatic profile selection mode, switch to the recom‐
90 mended profile.
91 profile_mode
94 Show current profile selection mode.
95 off Unload tunings.
