Heat Datasource Driver - get_all implementation

launchpad blueprint: https://blueprints.launchpad.net/vitrage/+spec/heat-datasource-get-all

This blueprint describes the Heat driver for Vitrage Datasource, and its implementation for get_all Stacks and Stack Resources.

Problem description

Heat stacks should be added to Vitrage Graph via Vitrage Datasources. This requires writing a Datasource driver for heat.

The driver should support two modes:

• get_all: query all Heat Stacks.

• notifications: notify the datasource upon a change in a stack definition or state

This blueprint refers to get_all implementation.

Proposed change

Heat driver will be configured with:

• Poll interval in seconds (default: 600)

Every poll-interval seconds, Heat Driver will call Heat list all stacks API. The stacks will be converted to Vitrage datasource events and passed to Vitrage Graph queue.

Alternatives

None

Data model impact

Heat event will be sent to Vitrage Graph queue with the following properties:

Field	Description	Examples
stack_id	The stack UUID	e47e1be6-3598-46e6-bb63-0cc9a4e35ad7
name	The stack name	mystack
description	The stack description	mydescription
user_project_id	The ID of the tenant that owns the alarm	5542b27142154f30b32dea6238aa81aa
owner	The ID of the user that owns the alarm	5555527142154f30b32dea6238aa81aa
status	The stack status	in progress / failed
status_reason	The stack status reason	Stack create started ….
