Open Stack

Dear all,

Is there a guide on how to understand the design of datasource? I want to
extend the existing one and also try to create a custom datasource from
scratch.

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.

Currently I have the following questions

   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` ?
   3. Is there any other datasource type besides ALARM/RESOURCE?
   4. What does `aggregated values` and `priority` mean
   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.
