Is there any way to know if my callout uses TLS 1.0 or 1.1?

After upgrading my SAP server to support tls 1.0 salesforce, I want to know using which protocol version my callouts are going to SAP. Any suggestion would be appreciated.

You can go to login history to know about how users are accessing Salesforce and using which TLS protocol:

  However, as per the TLS 1.1 Disablement docs https://help.salesforce.com/articleView?id=000321556&type=1&mode=1

For any inbound and outbound requests, TLS 1.1 is disabled; instead, we require TLS 1.2 for ANY https connection to Salesforce.
