The watcher.decision_engine.model.collector.cinder Module¶

class watcher.decision_engine.model.collector.cinder.CinderClusterDataModelCollector(config, osc=None)[source]¶

Bases: watcher.decision_engine.model.collector.base.BaseClusterDataModelCollector

Cinder cluster data model collector

The Cinder cluster data model collector creates an in-memory representation of the resources exposed by the storage service.

execute()[source]¶

Build the storage cluster data model

class watcher.decision_engine.model.collector.cinder.ModelBuilder(osc)[source]¶

Bases: object

Build the graph-based model

This model builder adds the following data” - Storage-related knowledge (Cinder)

add_storage_node(node)[source]¶

add_storage_pool(pool)[source]¶

build_storage_node(node)[source]¶

Build a storage node from a Cinder storage node

Parameters:	node (Service) – A storage node

execute()[source]¶

Instantiates the graph with the openstack cluster data.

The graph is populated along 2 layers: virtual and physical. As each new layer is built connections are made back to previous layers.
