To keep up to date server side TLS configuration and don’t lose my clients I need to know what ssl ciphers and ssl version clients use. I can log it:
- %sslc - ssl_ciphers (ex: AES-SHA)
- %sslv - ssl_version (ex: TLSv1)
But I need only statistical information:
- last used
- number of uses
Is there a way to get this info without overloading HAProxy with expensive logs?
