<div>For proprietary datasource, I'm considering to adapt the api to common protocol/interface, e.g. RESTful, SNMP and etc and I wish to know how to add support for these interface.</div>
</div>
</div>
</blockquote>
<div>[Ifat]: Do you mean that you want to write a datasource that gets its information from SNMP/REST API? Note that for alarm datasources, we have in our roadmap to support OPNFV Doctor SB REST API[1]. Will it be relevant for your use cases?</div>

Some documents are found in <a href="https://github.com/openstack/vitrage-specs" rel="noreferrer" target="_blank">
https://github.com/openstack/vitrage-specs</a> and datasource seems to be related to synchronizer but I didn't find a dedicated spec.<br>

<div>[Ifat]: We started documenting the process of adding a new datasource, but the document is not final. We will try to finish it shortly. BTW, there are many other documents in Vitrage wiki page[2].</div>

1. How do I register a new datasource in an existing system?<br>
2. Is the type of datasource (ALARM/RESOURCE) configured in `/etc/vitrage/datasource_values/<datasource>.yaml` ?<br>

</blockquote>
</span>
<div>[Ifat]: No, it is configured in the datasource code. For information about datasource_values please see [3]</div>

3. Is there any other datasource type besides ALARM/RESOURCE?</blockquote>
</div>
</div>
</div>
</blockquote>
</span>
<div>[Ifat]: No, and at the moment we don’t see a need for that. Vitrage can hold resources of any type in a topology graph, and manage alarms that are raised on these resources. If you see a use case for other datasource types, let us know. </div>

5. What is the required data format for the datasource driver api? The inline comments give some brief description but didn't specify the api signature.<br>
Many thanks.<br>
</blockquote>
</div>
</div>
</div>
</blockquote>
</span>
<div>[Ifat]: This should be part of the datasource documentation that we need to add. But basically, the driver should return a dictionary with few predefined fields (like datasource type, timestamp), and add whatever data is needed for the datasource. Then,
the datasource transformer will transform this data into a vertex and decide where to connect it to the graph.</div>
