nginx 日志

   

nginx默认的级别

log_format combined '$remote_addr - $remote_user [$time_local] '
                    '"$request" $status $body_bytes_sent '
                    '"$http_referer" "$http_user_agent"';

log_format指令中常用的一些变量

$bytes_sent    发送给客户端的总字节数
$body_bytes_sent    发送给客户端的字节数，不包括响应头的大小
$connection    连接序列号
$connection_requests    当前通过连接发出的请求数量
$msec    日志写入时间，单位为秒，精度是毫秒
$pipe    如果请求是通过http流水线发送，则其值为"p"，否则为“."
$request_length    请求长度（包括请求行，请求头和请求体）
$request_time    请求处理时长，单位为秒，精度为毫秒，从读入客户端的第一个字节开始，直到把最后一个字符发送张客户端进行日志写入为止
$status    响应状态码
$time_iso8601    标准格式的本地时间,形如“2017-05-24T18:31:27+08:00”
$time_local    通用日志格式下的本地时间，如"24/May/2017:18:31:27 +0800"
$http_referer    请求的referer地址。
$http_user_agent    客户端浏览器信息。
$remote_addr    客户端IP
$http_x_forwarded_for    当前端有代理服务器时，设置web节点记录客户端地址的配置，此参数生效的前提是代理服务器也要进行相关的x_forwarded_for设置。
$request    完整的原始请求行，如 "GET / HTTP/1.1"
$remote_user    客户端用户名称，针对启用了用户认证的请求
$request_uri    完整的请求地址，如 "https://daojia.com/"

json化日志 

escape=json 能把body里的16进制直接转成字符串

   log_format json escape=json '{ "@timestamp": "$time_iso8601", '
                  #'"server_host":"$server_addr",''"server_addr":"192.166.208.230",'
                  '"http_host":"$http_host",'
                  '"nginx_version":"$nginx_version",'
                  '"remote_addr":"$remote_addr",'
                  '"remote_user":"$remote_user",'
                  '"request":"$request",'
                  '"request_method":"$request_method",'
                  '"http_user_agent":"$http_user_agent",'
                  '"size":$body_bytes_sent,'
                  '"responsetime":$request_time,'
                  '"upstreamtime":"$upstream_response_time",'
                  '"upstreamhost":"$upstream_addr",'
                  '"url":"$uri",'
                  '"http_x_forwarded_for":"$http_x_forwarded_for",'
                  '"referer":"$http_referer",'
                  '"scheme":"$scheme",'
                  '"server_protocol":"$server_protocol",'
                  '"status":"$status"}';

 结果

{ "@timestamp": "2022-01-29T15:37:58+08:00", "server_addr":"192.166.208.111","http_host":"192.166.208.111:8899","nginx_version":"1.18.0","remote_addr":"192.167.14.30","remote_user":"-","request":"POST /platformcmd/index HTTP/1.1","request_method":"POST","http_user_agent":"okhttp/3.8.1","size":53,"responsetime":1.031,"upstreamtime":"1.031","upstreamhost":"127.0.0.1:12300","url":"/platform/index","http_x_forwarded_for":"-","referer":"-","scheme":"http","server_protocol":"HTTP/1.1","status":"200"}
