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.

32              plugins List all available plugins.
33
34
35                     -v, --verbose List  plugin's  configuration  options  and
36                     their hints.
37

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