Unfortunately, Azure Event Hubs Standard tier doesn’t provide a direct way to check the authentication type for active connections in real-time. This feature is available in the Premium and Dedicated tiers, which offer more advanced monitoring and logging capabilities.
However, you can use Azure Monitor to track metrics like Incoming Messages and Throttled Requests to get an idea of activity levels. For authentication types, you can refer to the authentication methods supported by Azure Event Hubs, such as Shared Access Signature (SAS) and Azure Active Directory (AAD) OAuth.

If upgrading isn’t an option, you might consider implementing custom logging within your application to track authentication types and connection details.
