DESCRIPTION

15       This  command  line utility allows you to switch between user definable
16       tuning profiles. Several predefined profiles are already included.  You
17       can  even  create your own profile, either based on one of the existing
18       ones by copying it or make a completely new one. The distribution  pro‐
19       vided  profiles  are  stored in subdirectories below /usr/lib/tuned and
20       the user defined profiles in subdirectories below /etc/tuned. If  there
21       are  profiles  with the same name in both places, user defined profiles
22       have precedence.

OPTIONS

26       list   List all available profiles.
27
28
29       active Show current active profile.
30
31
32       profile [PROFILE_NAME]
33              Switches to the given profile. If none is given then all  avail‐
34              able  profiles are listed. If the profile given is not valid the
35              command gracefully exits without performing any operation.
36
37
38       verify Verifies current profile against system settings. Outputs infor‐
39              mation  whether  system  settings  match  current profile or not
40              (e.g. somebody modified a sysfs/sysctl value by hand).  Detailed
41              information  about  what  is checked, what value is set and what
42              value is expected can be found in the log.
43
44
45       recommend
46              Recommend a profile suitable for  your  system.  Currently  only
47              static  detection  is implemented - it decides according to data
48              in /etc/system-release-cpe and virt-what output. The  rules  for
49              autodetection  are  defined  in  the  file /usr/lib/tuned/recom‐
50              mend.d/50-tuned.conf. The default rules recommend profiles  tar‐
51              geted  to  the  best  performance,  or  the  balanced profile if
52              unsure.
53
54              The default rules can be overridden by the  user  by  putting  a
55              file named recommend.conf into /etc/tuned, or by creating a file
56              in    the    /etc/tuned/recommend.d    directory.    The    file
57              /etc/tuned/recommend.conf  is  evaluated  first.  If no match is
58              found, the files in  the  /etc/tuned/recommend.d  directory  are
59              merged  with  the files in the /usr/lib/tuned/recommend.d direc‐
60              tory (if there is a file with the same name in both directories,
61              the  one  from /etc/tuned/recommend.d is used) and the files are
62              evaluated in alphabetical order. The  first  matching  entry  is
63              used.
