DEPRECATED: static physical datasource configuration

The static physical datasource is deprecated and will be removed in Stein release.

Please use the static datasource instead.

Overview

The Static Physical datasource allows users to integrate the physical topology into Vitrage. Physical topology includes switches and their connection to other switches and physical hosts.

This datasource is static - pre-configured in a file. This is sufficient in many cases where the physical topology is relatively unchanging.

Configure Access to Static Physical

The following should be set in /etc/vitrage/vitrage.conf, under [static_physical] section:

Name	Description	Default Value
directory	Directory path from where to load the configurations	/etc/vitrage/static_datasources/
changes_interval	Interval of checking changes in the configuration files	30 seconds
entities	Static physical entity types list	switch

Configure Static Physical Mapping

Physical configuration is made for configuring statically physical entities, and their relationships to other entities in the topology.

Some physical entities, such as switches, can not be retrieved from OpenStack, and so are defined here.

There may be more than one configuration file. All files will be read from /etc/vitrage/static_datasources/. See previous section on how to configure this location.

Format

entities:
  - name: <Physical entity name as appears in configuration>
    id: <Physical entity id as appears in configuration>
    type: <Physical entity type - see below for details>
    state: <default resource state>
    relationships:
      - type: <Physical entity type it is connected to - see below for details>
        name: <Name of physical entity as appears in configuration>
        id: <Id of physical entity as appears in configuration>
        relation_type: <Relation name>
      - type: ...
...

Notes:

• The "type" key must match the name of a type from an existing datasource.
• Type names appear, for each datasource, in its __init__.py file.
• For example see /workspace/dev/vitrage/vitrage/datasources/nova/host/__init__.py

Example

The following will define a switch that is attached to host-1 and is a backup of switch-2

entities:
  - type: switch
    name: switch-1
    id: switch-1 # should be same as name
    state: available
    relationships:
      - type: nova.host
        name: host-1
        id: host-1 # should be same as name
        relation_type: attached
      - type: switch
        name: switch-2
        id: switch-2 # should be same as name
        relation_type: backup
