AWS log Insights 解析 NGINX 日志

Question

我正在尝试使用 aws log insights 运行查询包含 nginx 日志的我的日志组。

这是我在我的 ec2 机器上设置的日志格式：

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

示例 NGINX 日志：

xx.xx.xx.xx - - [10/Nov/2020:15:28:30 +0530] "POST /xx HTTP/1.1" 200 57 "https://xxxx.in/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_4) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/85.0.4183.121 Safari/537.36" "-"

我正在尝试使用带有以下代码的日志洞察来解析它：

parse @message '* - - [*] "* * *" * * "-" "*"' as remote_addr, timestamp, request_type, location, protocol, response_code, body_bytes_sent

我收到以下错误：

Expression is invalid: parse@message'* - - [*] "* * *" * * "-" "*"'asremote_addr,timestamp,request_type,location,protocol,response_code,body_bytes_sent

如有任何帮助，我们将不胜感激

Answer 1

您已完成 99%。所缺少的只是匹配选择器和输出变量的数量，所以如果你将 user_agent 附加到你的列表，它就会开始工作。

示例工作查询：

fields @message
| parse @message '* - - [*] "* * *" * * "-" "*"' as remote_addr, timestamp, request_type, location, protocol, response_code, body_bytes_sent, user_agent
| display request_type, location

Answer 2

如果有 referrer 和 user_agent

会更好

fields @timestamp, @message
| parse @message '* - - [*] "* * *" * * "*" "*"' as remote_addr, timestamp, request_type, location, protocol, response_code, body_bytes_sent, referrer, user_agent
| display @timestamp, remote_addr, request_type, location, protocol, response_code, body_bytes_sent, referrer, user_agent
| sort @timestamp desc
