nginx日志格式定义和nginx.conf配置模板说明

在http的功能里添加log_format模块，内容如下：

log_format main escape=json '{ "@timestamp": "$time_iso8601", '

'"remote_addr": "$remote_addr",'
'"request_time": "$request_time",'
'"upstream_response_time": "$upstream_response_time",'
'"status": $status,'
'"x_forwarded": "$http_x_forwarded_for",'
'"http_referer": "$http_referer",'
'"request": "$request",'
'"upstream_addr": "$upstream_addr",'
'"body_bytes_sent":$body_bytes_sent,'
'"request_body":$request_body,'
'"http_user_agent": "$http_user_agent" }';

access_log /usr/local/openresty/nginx/logs/access.log main;
