tuned

Ansible Role: Tuned

Build Status Ansible Role

Installs and configures the tuned daemon for setting system tuning profiles. Supported on EL7.

Requirements

None.

Role Variables

The available built-in profiles on EL7 are:

  • balanced
  • desktop
  • latency-performance
  • network-latency
  • network-throughput
  • powersave
  • throughput-performance
  • virtual-guest
  • virtual-host

Change the active tuned profile using one of the built-in profiles above:

tuned_active_builtin_profile: "throughput-performance"

Change the active tuned profile by creating a custom tuned profile. See example below on how to build a custom tuned profile:

tuned_active_custom_profile: ""

Dependencies

None.

Example Playbooks

To use the role's default profile, throughput-performance, just apply the role:

- hosts: servers
  roles:
     - giovtorres.tuned

To use one of the other available built-in profiles, set the tuned_active_builtin_profile variable:

- hosts: servers
  vars:
    tuned_active_builtin_profile: "virtual-guest"
  roles:
     - giovtorres.tuned

To build a custom profile, create a dictionary using the tuned_active_custom_profile variable with the name and sections items, where sections contains the name of the section in the config file and a list of option/value pairs that go into that given section.

- hosts: all
  vars:
    tuned_active_custom_profile:
      name: my_custom_profile
      sections:
        - name: main
          params:
            - option: summary
              value: Test
            - option: include
              value: throughput-performance
        - name: sysctl
          params:
            - option: vm.dirty_ratio
              value: 30
            - option: vm.swappiness
              value: 30
        - name: vm
          params:
            - option: transparent_hugepages
              value: never
  roles:
    - giovtorres.tuned

The above playbook results in the following configuration output:

[main]
summary=Test
include=throughput-performance

[sysctl]
vm.dirty_ratio=30
vm.swappiness=30

[vm]
transparent_hugepages=never
