get https://{hostname}/datastream-config-api/v3/log//datasets-fields
Lists available data set fields you can choose to monitor in your logs in a stream configuration. Use the logType and productId parameters to get data sets available for a specific log type or product. Requests without productId return data set fields available for all products, omitting product-specific fields. Run this operation to get the datasetFieldId and datasetFieldName values you need to create or edit a stream.
