Telegraf is an open-source plugin-driven server agent used for collecting and reporting data from different databases, systems, and application servers. It is written in the Go language and supports different platforms including Linux, Windows, and macOS. In this tutorial, we will guide you through the process of installing Telegraf on MX Linux Latest.
Before installing Telegraf on MX Linux Latest, ensure that you have the following prerequisites:
Telegraf requires some dependencies to be installed on the system. To install them, open the terminal and run the following command:
sudo apt-get update && sudo apt-get install -y wget gnupg2
Telegraf is developed and maintained by InfluxData, so we need to add their repository to the system. To do this, add the following key to the system:
wget -qO- https://repos.influxdata.com/influxdb.key | sudo apt-key add -
After adding the key, add the InfluxData repository to the system by running the following command:
echo "deb https://repos.influxdata.com/debian buster stable" | sudo tee /etc/apt/sources.list.d/influxdb.list
The above command will add the repository to a new file called influxdb.list in the /etc/apt/sources.list.d/ directory.
After adding the repository, update the system package index and install Telegraf as follows:
sudo apt-get update && sudo apt-get install -y telegraf
The above command will download Telegraf and install it on the system.
Once installed, Telegraf must be configured. Open the Telegraf configuration file using your favorite text editor:
sudo nano /etc/telegraf/telegraf.conf
In this file, you will find several configuration options such as tags, inputs, and outputs. By default, Telegraf comes with some sample configurations that you can customize according to your needs. For example, to send the output to an InfluxDB instance running on localhost on port 8086, uncomment and change the following lines:
[[outputs.influxdb]]
urls = ["http://localhost:8086"]
Also, if you want to collect the memory usage statistics of the system, uncomment and modify the following lines in the inputs section:
[[inputs.mem]]
Save the changes made to the configuration file and exit the text editor using the CTRL + X, then Y, then Enter key sequence.
After configuring Telegraf, you need to start and verify it. To start Telegraf, run the following command:
sudo systemctl start telegraf
To verify that Telegraf is running, you can use the following command:
sudo systemctl status telegraf
If everything is configured correctly, the output should resemble the following:
