    '"ip": "$remote_addr", '
    '"server_name": "$server_name", '
    '"remote_user": "$remote_user", '
    '"remote_port": "$remote_port", '
    '"time": "$time_iso8601", '
    '"user_agent": "$http_user_agent", '
    '"user_id_got": "$uid_got", '
    '"user_id_set": "$uid_set", '
    '"request": "$request", '

    '"request_time": "$request_time", '
    '"request_method": "$request_method", '
    '"geoip_country_code": "$geoip_country_code", '
    '"http_referrer": "$http_referer" }';
access_log /var/log/nginx/access.log json_combined;
