nginx错误日志中的每个字段是什么意思？

Question

2019/05/18 00:32:24 [error] 4429#0: *3164 directory index of "/var/www/" is forbidden, client: 192.168.16.1, server: , request: "GET http://www.123cha.com/ HTTP/1.1",      host: "www.123cha.com"

如上所示：

                                      2019/05/18 00:32:24 --> create time ?

                                                  [error] --> error level ?

4429#0: *3164 directory index of "/var/www/" is forbidden --> ?


                                    client: 192.168.1.1 --> ?

                                                 server: --> Nginx server?

          request: "GET http://www.123cha.com/ HTTP/1.1" --> to nginx?

                                  host: "www.123cha.com" --> This is not my server

在哪里可以找到详细的文件？谢谢！
