In the prometheus source connector, I try to call prometheus api：/api/v1/query_range to obtain monitoring data as event. Is this appropriate? Please give me some advice.

@willimpo SDK is preferred and OpenAPI is acceptable. You may warp prometheus response into an object instead of json string for a better readability.

Using HTTP API is OK, it is necessary to pay attention to the indicator data type of the query, the return format, and the design of the query parameters.
