SYNOPSIS

DESCRIPTION

12       This  man page documents format of the Tuned global configuration file.
13       The tuned-main.conf file uses the ini-file format.

17       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
25
26       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
34
35       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
48
49       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
60
61       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
70
71       reapply_sysctl=BOOL
72              This controls  whether  to  reapply  sysctl  settings  from  the
73              /etc/sysctl.conf,                          /etc/sysctl.d/*.conf,
74              /usr/lib/sysctl.d/*.conf,        /usr/local/lib/sysctl.d/*.conf,
75              /lib/sysctl.d/*.conf,  /run/sysctl.d/*.conf,  i.e. all locations
76              supported by sysctl --system after  Tuned  sysctl  settings  are
77              applied, i.e. if set to True or 1 Tuned sysctl settings will not
78              override system sysctl settings. If set  to  False  or  0  Tuned
79              sysctl settings will override system sysctl settings. By default
80              it's set to True.
81
82
83       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.
