Is it possible to find the producer of Event Hub Messages and determine what TLS version is being used?

Question

Hello,

I have three Event Hubs that were created couple of years back and i'm trying to determine:

• the IPs of the Event hub messages -> https://learn.microsoft.com/en-us/answers/questions/1120359/is-it-possible-to-find-the-producer-of-event-hub-m is this the only way to obtain the caller IP?
• the TLS version that is being used

Could you kindly provide some guidance?

Thanks,

Fabio

Hello , Welcome to MS Q&A

To find the producer IP and TLS version for Event Hubs messages in Azure, you can follow these steps:

Finding the Producer IP:

• Utilize network monitoring tools like Fiddler to capture the network traffic from your client application. By analyzing the captured traffic, you can identify the IP address of the producer.
  • Another method is to enable diagnostic logs for your Event Hubs namespace. These logs can provide information about the incoming requests, including the IP addresses of the producers.
  Determining the TLS Version:

  - Configure your client application to use a specific version of TLS, such as TLS 1.2. Ensure that the operating system supports the desired TLS version.
  
     - You can also enforce a minimum required version of TLS for requests to your Event Hubs namespace. This can be done through the Azure portal or using Azure CLI.
  

For detailed steps and examples, you can refer to the following Azure documentation:

• Configure Transport Layer Security (TLS) for an Event Hubs client application
• Enforce a minimum required version of Transport Layer Security (TLS) for requests to an Event Hubs namespace

Please let us know if any questions

Kindly accept answer if it helps

Hello @Deepanshu katara , thank for your prompt reply.

I don't have access to client application code.

I was wondering if diagnostic logs can contain the tls version used by a single client request.

Looking at event hub diagnostic table schemas I didn't find that information.

Could you provide some additional information?
