This tutorial will guide you through the process of installing Fluentd on the latest version of Linux Mint. Fluentd is an open-source log collector that allows you to unify data collection and ingestion from different sources. It supports various input and output plugins, making it suitable for different use cases.

Step 1: Install Required Dependencies

Before installing Fluentd, we need to install some dependencies required by Fluentd. To do this, open the terminal by pressing Ctrl+Alt+T and run the following command:

sudo apt update
sudo apt install -y ruby ruby-dev build-essential

This command will update the package list and install Ruby, Ruby development headers, and build-essential package.

Step 2: Install Fluentd

We can install Fluentd by running the following command:
