=================================
Outlet Temperature Based Strategy
=================================
Synopsis
--------
**display name**: ``Outlet temperature based strategy``
**goal**: ``thermal_optimization``
.. watcher-term:: watcher.decision_engine.strategy.strategies.outlet_temp_control
Requirements
------------
This strategy has a dependency on the host having Intel's Power
Node Manager 3.0 or later enabled.
Metrics
*******
The *outlet_temperature* strategy requires the following metrics:
========================================= ============ ======= =======
metric service name plugins comment
========================================= ============ ======= =======
``hardware.ipmi.node.outlet_temperature`` ceilometer_ IPMI
========================================= ============ ======= =======
.. _ceilometer: https://docs.openstack.org/ceilometer/latest/admin/telemetry-measurements.html#ipmi-based-meters
Cluster data model
******************
Default Watcher's Compute cluster data model:
.. watcher-term:: watcher.decision_engine.model.collector.nova.NovaClusterDataModelCollector
Actions
*******
Default Watcher's actions:
.. list-table::
:widths: 30 30
:header-rows: 1
* - action
- description
* - ``migration``
- .. watcher-term:: watcher.applier.actions.migration.Migrate
Planner
*******
Default Watcher's planner:
.. watcher-term:: watcher.decision_engine.planner.weight.WeightPlanner
Configuration
-------------
Strategy parameter is:
============== ====== ============= ====================================
parameter type default Value description
============== ====== ============= ====================================
``threshold`` Number 35.0 Temperature threshold for migration
``period`` Number 30 The time interval in seconds for
getting statistic aggregation from
metric data source
============== ====== ============= ====================================
Efficacy Indicator
------------------
None
Algorithm
---------
For more information on the Outlet Temperature Based Strategy please refer to:
https://specs.openstack.org/openstack/watcher-specs/specs/mitaka/implemented/outlet-temperature-based-strategy.html
How to use it ?
---------------
.. code-block:: shell
$ openstack optimize audittemplate create \
at1 thermal_optimization --strategy outlet_temperature
$ openstack optimize audit create -a at1 -p threshold=31.0
