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,  be‐
21              cause  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 ap‐
32              plicable 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
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
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.
