<p>Arghya's suggestion is correct but there are more options that can help you.</p>

<ol>
<li><p>You can set <code>flush_mode</code> to <code>immediate</code> in order to force flush or set or set additional flush parameters in order to adjust it to your needs. You can read more about it here: <a href="https://docs.fluentd.org/output#control-flushing" rel="nofollow noreferrer">Control Flushing</a>.</p></li>
<li><p>You can also consider using <a href="https://docs.fluentd.org/deployment/signals#sigusr1" rel="nofollow noreferrer">SIGUSR1 Signal</a>:</p></li>
</ol>

<blockquote>
  <p>Forces the buffered messages to be flushed and reopens Fluentd's log.
  Fluentd will try to flush the current buffer (both memory and file)
  immediately, and keep flushing at <code>flush_interval</code>.</p>

<p>Please let me know if that helped. </p>
