Ansible Role: Tuned

This role installs and sets up the tuned service to help optimize system settings. It works on EL7.

Requirements

No special requirements.

Role Variables

The built-in profiles available on EL7 are:

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

You can change the active tuned profile to one of the built-in profiles above:

tuned_active_builtin_profile: "throughput-performance"

You can also create your own custom tuned profile. See the example below for details:

tuned_active_custom_profile: ""

Dependencies

No dependencies.

Example Playbooks

To use the default profile, throughput-performance, simply apply the role:

- hosts: servers
  roles:
     - giovtorres.tuned

To use a different built-in profile, set the variable tuned_active_builtin_profile:

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

To create a custom profile, use the tuned_active_custom_profile variable, including name and sections items. The sections should define the section name in the config file and a list of option/value pairs for that 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 will produce the following configuration output:

[main]
summary=Test
include=throughput-performance

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

[vm]
transparent_hugepages=never
