In this tutorial, we will be covering how to install Fluentd on POP! OS Latest, which is an open-source log collector tool. Fluentd is capable of collecting logs from various sources including Linux servers, AWS logs, and Docker containers.

Prerequisites

Before we begin, make sure you have the following prerequisites:

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:

Create a configuration file named fluent.conf in the directory using the following command:

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
</match>

Save the file and exit the editor.

Step 5: Test Fluentd
