[Nginx&TLS] How to make log show a successful exchange of digital certificates.

[dencivi]

My log format

log_format  tls_log  '$remote_addr $remote_user [$time_local] "$request"
$http_host '
                  '$status $upstream_status $body_bytes_sent "$http_referer"
'
                  '"$http_user_agent" $upstream_addr
[$request_time/$upstream_response_time] '
                  '[SSL]: $ssl_protocol $ssl_cipher
SSL_CLIENT{Verify:$ssl_client_verify, Serial:$ssl_client_serial,
SDN:$ssl_client_s_dn, IDN:$ssl_client_i_dn}';
