我的英语不好，对不起...

这些天来，我总是在 AWS EC2（Amazon Linux AMI 版本 2014.03）上测试 td-agent。从 nginx 输入日志并将日志输出到 S3 就可以了，这非常好！

然后我想要 praser 日志到 json，当我制作源格式“nginx”时，它说

"  2015-03-31 00:12:24 +0800 [warn]: pattern not match: "95.218.58.120 - [2015-03-30T16:11:40+08:00] \"GET /provider.txt HTTP/1.1\" 200 726 \"-\" \"FreePP 2.9.5.159 (iPhone; iPhone OS 8.1.3; ar_SA) [65075070]\" "

我认为mybe我的nginx日志不是默认的。然后，我为此做了正则表达式，

format /^(?<remote>[^ ]*) (?<user>[^ ]*) \[(?<time>[^\]]*)\] "(?<method>\S+)(?: (?<path>[^\"]*)+\S*)?" (?<code>[^ ]*) (?<size>[^ ]*) "(?<referer>[^\"]*)" "(?<agent>[^\"]*)"?$/

我的日志是：) 178.152.203.39 - [2015-03-31T00:18:10+08:00] "GET /provider.txt HTTP/1.1" 200 726 "-" "Dalvik/1.6.0 (Linux; U; Android 4.3; GT-I9300 Build/JSS15J"

重新启动 td-agent ，td-agent 日志似乎没问题。但没有找到输出，我的 cpu 100%，任何人都可以帮助我吗？非常感谢 ！！！

正则表达式有问题，我修改它

格式 /^(?[^ ] ) (?[^ ] ) [(?[^]] )] "(?\S+) (?[^"] )" (?[^ ] ) (?[^ ] ) "(?[^\"] )" "(?[^\"] )"/

铅被爱了。谢谢 ！

重新启动 td-agent ，td-agent 日志似乎没问题。但没有找到输出，

从您的配置中，您可以single_value在文件输出中使用。 single_value几乎是none解析器。如果你想使用single_value，你应该none在尾部输入中使用。

请参阅本文中的格式部分：http: //docs.fluentd.org/articles/out_file#format
