Is it possible to obtain logs for TLS version information of mqtt connection? I have checked the log table reference in the following website, but I could not find any table that stores the information : https://learn.microsoft.com/ja-jp/azure/azure-monitor/reference/tables/tables-resourcetype#iot-hub. Please let me know if there is any way to obtain this information. Thank you.

    I don't believe so. I found Azure Monitor: Route connection events to logs where it points to the Connection logs you collect in Azure Monitor. The logs indicate the protocol type in properties but I wasn't able to see anything related to TLS type. Even under Monitor device connection status I don't see any mentions of TLS, just under the Hub itself. I'll reach out to the team to see if this is available or not.
