Fluentd not writing logs into amazon s3
<p>I am trying to test the fluentd-s3-plugin yet at the moment it is not posting my logs into s3 bucket.
I am running everything on ubuntu xenial, having installed fluentd with td-agent.
The following is the td-agent log file located at <em>/var/log/td-agent/td-agent.log</em></p>

<p>Also here is my <em>td-agent.conf</em> file</p>

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

&lt;match nginx.log&gt;
    @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
&lt;/match&gt;
</code></pre>

<p>I would really appreciate any answer on why fluentd is not posting the logs into s3 bucket.</p>
