Telegraf is an open-source agent for collecting, processing, aggregating, and sending metrics of all kinds from systems, IoT devices, and sensors. In this tutorial, we will provide you with a detailed guide on how to install Telegraf on Linux Mint Latest.
Before installing Telegraf, you first need to have InfluxDB installed on your system. InfluxDB is the underlying storage engine for Telegraf.
To install InfluxDB, run the following command:
sudo apt-get install influxdb
Once installed, you can start the InfluxDB service and enable it to start at boot time with the following commands:
sudo systemctl start influxdb
sudo systemctl enable influxdb
You can confirm that InfluxDB is running by executing the following command:
sudo systemctl status influxdb
To install Telegraf, you need to add the InfluxData GPG key to the system.
To add the key, use the following commands:
curl -sL https://repos.influxdata.com/influxdb.key | sudo apt-key add -
After you have added the GPG key, you need to add the InfluxData repository to the system.
To add the repository, create a new file named influxdb.list in the /etc/apt/sources.list.d/ directory, and add the following line to it:
deb https://repos.influxdata.com/debian buster stable
Now you can install Telegraf by running the following command:
sudo apt-get update
sudo apt-get install telegraf
Once installed, you can start the Telegraf service and enable it to start at boot time with the following commands:
sudo systemctl start telegraf
sudo systemctl enable telegraf
You can confirm that Telegraf is running by executing the following command:
sudo systemctl status telegraf
By default, Telegraf comes with a sample configuration file located at /etc/telegraf/telegraf.conf. You can customize this file to suit your needs.
To edit the configuration file, open it with a text editor, for example, nano:
sudo nano /etc/telegraf/telegraf.conf
In the configuration file, you can enable or disable various input and output plugins, set the data collection intervals, and configure the InfluxDB output.
When done modifying the configuration file, save and close it.
That’s it! You have successfully installed and configured Telegraf on your Linux Mint Latest system. You can now use Telegraf to collect and send metrics to InfluxDB.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
