Step 1: Update your system

The first step before you install any package is to update your system. Run the following command to update your system:

sudo mkdir /etc/fluentd/
sudo touch /etc/fluentd/fluent.conf

Open the configuration file using your favorite editor:

sudo nano /etc/fluentd/fluent.conf

Now, add the following configuration to the file:

<source>
  @type forward
  port 24224
</source>

<match **>
  @type file
  path /var/log/td-agent/td-agent.log
  flush_interval 10s
  buffer_chunk_limit 512k

Save the file and exit the editor.
