Telegraf is an open-source server agent that can be used to collect metrics and data from various systems and applications. It can collect, process, and output the data in various formats, including InfluxDB, Prometheus, and Graphite. This tutorial explains how to install Telegraf on EndeavourOS.

Prerequisites

Before starting with the installation process, make sure that:

• You have root or sudo privileges to install packages on your EndeavourOS system.
• You have updated your package repositories using the following command:

sudo pacman -Syu

Step 1: Install Telegraf

To install Telegraf on EndeavourOS, follow the steps below:

1. Open the terminal on your EndeavourOS system.
2. Add the InfluxData repository gpg key:

sudo pacman-key -r 8F0871F202119294
sudo pacman-key --lsign-key 8F0871F202119294

3. Add the InfluxData repository to the Pacman package manager:

echo -e "[influxdb]\nServer = https://repos.influxdata.com/arch/\$arch\n" | sudo tee /etc/pacman.d/influxdb.repo

4. Refresh the package repositories using the following command:

sudo pacman -Syy

5. Install Telegraf using the Pacman package manager:

sudo pacman -S telegraf

Step 2: Configure Telegraf

After installing Telegraf, you need to configure it to collect data and send it to the desired output. Telegraf uses configuration files in TOML format located at /etc/telegraf/telegraf.conf. The default configuration file contains various input and output plugins commented out.

To configure Telegraf, follow the steps below:

1. Locate telegraf.conf configuration file by running:

sudo nano /etc/telegraf/telegraf.conf

2. Uncomment and edit the desired input and output plugins. For example, to collect system metrics using the system plugin and send them to InfluxDB, uncomment the following lines:

[[inputs.system]]
  metrics = ["cpu", "mem", "load", "net", "swap", "disk"]
  
[[outputs.influxdb]]
  urls = ["http://localhost:8086"]
  database = "telegraf"

3. Save the changes and close the file.

Step 3: Start and Enable Telegraf

To start and enable Telegraf to run automatically on system boot, follow the steps below:

1. Start Telegraf using the following command:

sudo systemctl start telegraf

2. Enable Telegraf to automatically start on system boot:
