Hi Yujun, Please see my answers below.
Best Regards, Ifat. From: Yujun Zhang Date: Tuesday, 9 August 2016 at 12:06 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. [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? Some documents are found in https://github.com/openstack/vitrage-specs and datasource seems to be related to synchronizer but I didn't find a dedicated spec. [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]. 1. How do I register a new datasource in an existing system? 2. Is the type of datasource (ALARM/RESOURCE) configured in `/etc/vitrage/datasource_values/<datasource>.yaml` ? [Ifat]: No, it is configured in the datasource code. For information about datasource_values please see [3] 3. Is there any other datasource type besides ALARM/RESOURCE? [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. 4. What does `aggregated values` and `priority` mean [Ifat]: Detailed in [3] 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. Many thanks. [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.
