@Rafal Fraczek , thank you for the question and apologies for the delayed response. I have been trying to get the required information for this question.
For "Data ingestion" and "Analytics logs", both are based on Log Analytics. Therefore, to get all the pricing details of data ingestion, you can use the following filter:
$filter=serviceFamily eq 'Management and Governance' and productName eq 'Log Analytics'
Managed Prometheus is still in preview based on the Products available by region, therefore it seems that its information is not available through this API. I have requested more clarification and will get back to this thread as soon as I have any.
Hope this helps.
