log SSL/TLS protocol version (1 reply)

Hello,

We use Haproxy in front of HTTP servers, SSL termination is done on HAproxy.

Is there a way to have HAproxy log the SSL or TLS protocol version (TLS
1.0 / 1.1 / 1.2) or specific cipher that was used for requests ?

I know this is negociated between each client and the HAproxy server,
but I would like to know which clients use outdated protocols.

Thanks.
