We would like to know what protocols (TLS 1.0, 1.1, or 1.2) are used by the clients while making API requests to Edge. Want to get data around how many clients are using TLS 1.0, 1.1 or 1.2. Is it possible to get this information through Analytics ?

After some investigation, I figured out the following information. We have two options:

Option #1: Logs on Elastic Load Balancer

If we have Elastic Load Balancer (ELB) in front of the Apigee Router and the SSL termination happens on the ELB, then we can enable logs on the ELB.
The logs contain the information about the Client IP address and also the Protocol being used to communicate with Apigee Edge.
Refer to this link to understand the log entry format and what each of the fields represent to determine the Client IP and Protocol.

Option #2: Nginx Access Logs on Apigee Router

If the SSL termination happens on the Apigee Router, then Nginx access logs has a field named "jsonPayload.ssl_protocol" which will contain the information of the protocol being used by the clients to communicate with Edge.
- For ex:
  
  jsonPayload.ssl_protocol TLSv1.2
