一、在nginx http模組下加入下面

   log_format json '{"@timestamp":"$time_iso8601",'
                  '"host":"$server_addr",'
                  '"service":"nginxTest",'
                  '"trace":"$upstream_http_ctx_transaction_id",'
                  '"log":"log",'
                  '"clientip":"$remote_addr",
 
'
                  '"remote_user":"$remote_user",'
                  '"request":"$request",'
                  '"http_user_agent":"$http_user_agent",'
                  '"size":$body_bytes_sent,'
                  '"responsetime":$request_time,'
                  '"upstreamtime":"$upstream_response_time",
 
'
                  '"upstreamhost":"$upstream_addr",'
                  '"http_host":"$host",'
                  '"url":"$uri",'
                  '"domain":"$host",'
                  '"xff":"$http_x_forwarded_for",'
                  '"referer":"$http_referer",'
                  '"status":"$status"}
 
';
    access_log /var/log/nginx/access.log json ;

二、重啟nginx後檢視日誌

cat/var/log/nginx/access.log
