I want to implement a data source that supports viewing the alert list through the Alert list panel. How can I achieve this?
It is possible they are simply using the Grafana API to get the alerts and filter them based on their own criteria Swagger Editor and for oncall you can use their own api Alerts HTTP API | Grafana OnCall documentation
@microopscn Alert list uses data from internal Grafana data source only. We support retrieving alerts in the Business Satellite data source and they can be nicely displayed using Business Text or grouped using Business Table panels.
