puppet-tuned

A module to manage tuneD service and its configuration.

Usage

Apply defaults, start service use auto-detected profile:

include tuned

Global configuration (typically stored in /etc/tuned/tuned-main.conf)

tuned::main:
  # Whether to use daemon. Without daemon it just applies tuning. It is
  # not recommended, because many functions don't work without daemon,
  # e.g. there will be no D-Bus, no rollback of settings, no hotplug,
  # no dynamic tuning, ...
  daemon: 1

  # Dynamicaly tune devices, if disabled only static tuning will be used.
  dynamic_tuning: 1

  # How long to sleep before checking for events (in seconds)
  # higher number means lower overhead but longer response time.
  sleep_interval: 1

  # Update interval for dynamic tunings (in seconds).
  # It must be multiply of the sleep_interval.
  update_interval: 10

  # Recommend functionality, if disabled "recommend" command will be not
  # available in CLI, daemon will not parse recommend.conf but will return
  # one hardcoded profile (by default "balanced").
  recommend_command: 1

  # Whether to reapply sysctl from /run/sysctl.d/, /etc/sysctl.d/ and
  # /etc/sysctl.conf.  If enabled, these sysctls will be re-appliead
  # after TuneD sysctls are applied, i.e. TuneD sysctls will not
  # override user-provided system sysctls.
  reapply_sysctl: 1

Switch to a predefined profile:

tuned::profile: balanced

see tuned-adm list for available options.

Custom profiles

Create custom profiles, first level key is the profile name, in this case custom.

tuned::profiles:
  custom:
    main:
      include: balanced
    sysctl:
      net.ipv4.tcp_fastopen: 3

This would generate /etc/tuned/custom/tuned.conf file with corresponding configuration.

Operators => can be used by passing value starting with >

tuned::profile: io
tuned::profiles:
  io:
    disk-sd:
      type: disk
      readahead: '>4096'
