tuned

Manages the activation of tuned

The following options only affect 'tuned'

Parameters

The following parameters are available in the tuned class:

• use_sysctl
• use_sysctl_post
• io_scheduler
• elevator_tune_devs
• tuning_interval
• diskmonitor_enable
• disktuning_enable
• disktuning_hdparm
• disktuning_alpm
• netmonitor_enable
• nettuning_enable
• cpumonitor_enable
• cputuning_enable
• package_ensure

use_sysctl

Data type: Boolean

This is the custom sysctl configuration file. Set to false to use only the ktune settings.

Default value: true

use_sysctl_post

Data type: Boolean

This is the ktune sysctl file. Any settings in this file will be applied after custom settings, overriding them. Comment this out to not use ktune settings.

Default value: false

io_scheduler

Data type: Tuned::IoSchedule

This is the I/O scheduler ktune will use. This will not override anything explicitly set on the kernel command line, nor will it change the scheduler for any block device that is using a non-default scheduler when ktune starts. You should probably leave this on "deadline", but "as", "cfq", and "noop" are also legal values.

Default value: 'deadline'

elevator_tune_devs

Data type: Array[String]

These are the devices, that should be tuned with the ELEVATOR

Default value: ['hd','sd','cciss']

tuning_interval

Data type: Integer

The number of seconds between tuning runs.

Default value: 10

diskmonitor_enable

Data type: Boolean

Enable the disk monitoring plugin.

Default value: true

disktuning_enable

Data type: Boolean

Enable the disk tuning plugin.

Default value: true

disktuning_hdparm

Data type: Boolean

Use 'hdparm' for disk tuning.

Default value: true

disktuning_alpm

Data type: Boolean

Use 'ALPM' when disk tuning.

Default value: true

netmonitor_enable

Data type: Boolean

Enable the network monitoring plugin.

Default value: true

nettuning_enable

Data type: Boolean

Enable the network tuning plugin.

Default value: true

cpumonitor_enable

Data type: Boolean

Enable the CPU monitoring plugin.

Default value: true

cputuning_enable

Data type: Boolean

Enable the CPU tuning plugin.

Default value: true

package_ensure

Data type: String

The ensure status of the tuned package

Default value: simplib::lookup('simp_options::package_ensure', { 'default_value' => 'installed' })

Data types

Tuned::IoSchedule

The Tuned::IoSchedule data type.

Alias of Enum['deadline', 'as', 'cfq', 'noop']
