Quick Start

Setup

include tuned

Full configuration options:

class { 'tuned':
  enabled             => true|false,  # enable state
  profile             => '...',       # active profile
  dynamic_tuning      => true|false,  # enable dynamic tuning
  sleep_interval      => ...,         # check interval for new commands
  update_interval     => ...,         # update interval for dynamic tuning
  majversion          => ...,         # override detected tuned major version
  main_conf           => '...',       # override absolute path to tuned-main.conf
  profiles_path       => '...',       # override absolute path to custom profiles
  active_profile_conf => '...',       # override filename with active profile
  packages            => [...],       # override list of packages to install
  services            => [...],       # override list of services to start
}

Custom profile:

tuned::profile { 'name':
  ensure  => present|absent, # ensure state
  data    => {...},          # hash of hashes for tuned.conf
  scripts => {...},          # hash of scripts content into profile dir.
}

Data hash format is following:

{
  'section1' => {
    'key1' => 'value1',
    'key2' => 'value2'
  },
  'section2' => {
    'key1' => 'value1',
    'key2' => 'value2'
  },
  ...
}

Scripts hash format is following:

{
  'script_name1' => 'script content1',
  'script_name2' => 'script content2',
  ...
}

Example:

class { 'tuned':
  profile        => 'virtual-host-cfq',
  dynamic_tuning => false,
}

tuned::profile { 'virtual-host-cfq':
  ensure  => present,
  data    => {
    'main'   => { 'include'  => 'virtual-host', },
    'disk'   => { 'elevator' => 'cfq', },
    'script' => { 'script'   => 'dummy.sh', },
  },
  scripts => {
    'dummy.sh' => "#!/bin/bash\n/bin/true",
  },
}
