Questions about the Azure Metrics Data plane API

Question

We are trying to use the Azure Metrics Data Plane API (https://techcommunity.microsoft.com/blog/azureobservabilityblog/azure-monitor--announcing-public-preview-of-azure-metrics-data-plane-api/3805986). We understand it has a limit of 360,000 API calls per hour. Is this limit applied at the subscription level, subscription + region level, or subscription + region + service principal level? Does the limit share across service principals, or does it apply individually to each service principal?

Additionally, are there any metrics available that can advise on current usage and indicate how much under or over the limit we are?

Answer 1

Thanks for posting your question in the Microsoft Q&A forum.

he Azure Metrics Data plane API offers a significant improvement in query limits compared to the existing Azure Resource Manager APIs. It allows up to 360,000 API calls per hour, which is a substantial increase from the 12,000 API calls per hour limit of the REST API. However, the search results do not provide specific information about how this limit is applied across different levels or service principals.Regarding the application of the limit, the search results do not explicitly state whether it's applied at the subscription level, subscription + region level, or subscription + region + service principal level. Similarly, there's no information on whether the limit is shared across service principals or applied individually to each one.As for metrics to monitor current usage and proximity to the limit, the search results do not mention any specific metrics or tools for this purpose.To get accurate and up-to-date information on these specific aspects of the Azure Metrics Data plane API, it would be best to:

• Consult the official Azure documentation for the most current details on API limits and their application.
• Contact Azure support directly for clarification on how the limits are applied across different levels and service principals.
• Inquire about any available metrics or tools for monitoring API usage and limit consumption
