==================================
Uniform Airflow Migration Strategy
==================================
Synopsis
--------
**display name**: ``Uniform airflow migration strategy``
**goal**: ``airflow_optimization``
.. watcher-term:: watcher.decision_engine.strategy.strategies.uniform_airflow.UniformAirflow
Requirements
------------
This strategy has a dependency on the server having Intel's Power
Node Manager 3.0 or later enabled.
Metrics
*******
The *uniform_airflow* strategy requires the following metrics:
================================== ============ ======= =======
metric service name plugins comment
================================== ============ ======= =======
``hardware.ipmi.node.airflow`` ceilometer_ IPMI
``hardware.ipmi.node.temperature`` ceilometer_ IPMI
``hardware.ipmi.node.power`` ceilometer_ IPMI
================================== ============ ======= =======
.. _ceilometer: http://docs.openstack.org/admin-guide/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 parameters are:
====================== ====== ============= ===========================
parameter type default Value description
====================== ====== ============= ===========================
``threshold_airflow`` Number 400.0 Airflow threshold for
migration Unit is 0.1CFM
``threshold_inlet_t`` Number 28.0 Inlet temperature threshold
for migration decision
``threshold_power`` Number 350.0 System power threshold for
migration decision
``period`` Number 300 Aggregate time period of
ceilometer
====================== ====== ============= ===========================
Efficacy Indicator
------------------
None
Algorithm
---------

How to use it ?
---------------
.. code-block:: shell
$ openstack optimize audittemplate create \
at1 airflow_optimization --strategy uniform_airflow
$ openstack optimize audit create -a at1 -p threshold_airflow=410 \
-p threshold_inlet_t=29.0 -p threshold_power=355.0 -p period=310
