Fluentd不写日志到亚马逊s3

我想测试fluentd-s3插件，但此刻它不会将我的日志发布到s3存储桶中。我在ubuntu xenial上运行所有的东西，用td-agent安装了fluentd。以下是位于/var/log/td-agent/td-agent.logFluentd不写日志到亚马逊s3

而且，这里是我的TD-agent.conf文件中的TD-代理日志文件

# Centralized nginx logs into Amazon s3 
<source> 
    type tail 
    format nginx 
    path /var/log/nginx/access.log 
    pos_file /var/log/td-agent/nginx-access.pos 
    tag nginx.log 
</source> 

<match nginx.log> 
    @type s3 
    s3_bucket xxxxxxx 
    aws_key_id xxxxxxxxxxxxxxxx 
    aws_sec_key xxxxxxxxxxxxxxxxxxxxxxxxxx 
    s3_region us-west-2 

    path logs/ 
    buffer_path /var/log/td-agent/s3 
    time_slice_format %Y%m%d%H%M 

    utc 

    format_json true 
    include_time_key true 
    buffer_chunk_limit 256m 
</match>

我真的很感激为什么fluentd不会将日志发布到s3存储桶中。

它看起来in_tail无法解析你的nginx日志。因此，fluentd没有发送所有日志到s3。 format nginx将组合日志格式视为默认值。

我认为你需要使用自定义格式来解析你的nginx日志。

<source> 
    type tail 
    format /^(?<remote>[^ ]*) (?<host>[^ ]*) (?<user>[^ ]*) \[(?<time>[^\]]*)\] "(?<method>\S+)(?: +(?<path>[^ ]*) +\S*)?" (?<code>[^ ]*) (?<size>[^ ]*)(?: "(?<referer>[^\"]*)" "(?<agent>[^\"]*)" "(?<forwarder>[^\"]*)")?/ 
    time_format %d/%b/%Y:%H:%M:%S %z 
    path /var/log/nginx/access.log 
    pos_file /var/log/td-agent/nginx-access.pos 
    tag nginx.log 
</source>

你可以用fluentd-ui测试你自己的正则表达式。 http://docs.fluentd.org/articles/fluentd-ui

感谢您的回答。我刚刚开始使用fluentd，现在我已经习惯了日志正则表达式格式（与ruby相同）。 – francotestori
