本人才疏学浅，若有纰漏，虚心请教
此教程记录如何对Nginx配置以JSON格式记录日志

1. 打开conf/nginx.conf文件，添加如下配置：

log_format log_json '{ "timestamp": "$time_iso8601", '
                        '"time_local": "$time_local", '
                        '"remote_addr": "$remote_addr", '
                        '"remote_user": "$remote_user", '
                        '"referer": "$http_referer", '
                        '"request": "$request", '
                        '"status": "$status", '
                        '"bytes": "$body_bytes_sent", '
                        '"http_referer": "$http_referer", '
                        '"agent": "$http_user_agent", '
                        '"x_forwarded": "$http_x_forwarded_for", '
                        '"upstr_addr": "$upstream_addr",'
                        '"upstr_host": "$upstream_http_host",'
                        '"ups_resp_time": "$upstream_response_time" }';

access_log logs/access.log log_json;

2. 检查配置是否有误，运行sbin/nginx -t，弹出如下提示则表示配置无误：

1
2
nginx: the configuration file /home/web/nginx//conf/nginx.conf syntax is ok
nginx: configuration file /home/web/nginx//conf/nginx.conf test is successful

3. 重启Nginx之后，监测日志
