Comment 0 for bug 1669950

given some generic source of information that can populate a database that can be monitored by a generic datasource driver, we can plugin in those additional datasources into Congress, e.g. relevant events/data from a telemetry system ala OPNFV VES (https://wiki.opnfv.org/display/ves/)

Some questions to answer:
- what forms of data / interfaces to support?
  - pushed events over oslo-messaging or another messaging bus?
  - pushed events over http/https? (already supported in fixed schema form with PushedDataSourceDriver, implemented by DoctorDriver)
  - relational dbms connection?
  - csv/json/yaml retrievable from URI?
- how does the schema (set of tables and their columns) get specified / computed?
