In this tutorial, we will show you how to install Telegraf on Ubuntu Server Latest.
Telegraf is an open source agent that collects metrics and data on the system it's running on. Telegraf can collect metrics from a variety of sources, such as operating systems, databases, and applications.
Before we install Telegraf, we need to make sure that the server is up-to-date and has all the necessary packages.
Before we start, it's a good idea to update the server with the latest software packages.
sudo apt update
sudo apt upgrade
To install Telegraf on Ubuntu Server, we will use the official InfluxData repository.
Add the InfluxData repository key:
curl -sL https://repos.influxdata.com/influxdb.key | sudo apt-key add -
Add the InfluxData repository:
echo "deb https://repos.influxdata.com/ubuntu bionic stable" | sudo tee /etc/apt/sources.list.d/influxdb.list
Update the apt package list:
sudo apt-get update
Install Telegraf:
sudo apt-get install telegraf
The Telegraf configuration file is located in /etc/telegraf/telegraf.conf.
You can edit this file to configure Telegraf. The default configuration is set up to collect metrics from the system, but you can customize it to your needs.
For example, to enable collection of metrics from PostgreSQL, you can uncomment the lines in the [[inputs.postgresql]] section and add your PostgreSQL connection details.
After making any changes to the configuration file, you need to restart the Telegraf service:
sudo systemctl restart telegraf
You can check if Telegraf is running by using the following command:
sudo systemctl status telegraf
If everything is working correctly, you should see output like this:
● telegraf.service - The plugin-driven server agent for reporting metrics into InfluxDB
Loaded: loaded (/lib/systemd/system/telegraf.service; enabled; vendor preset: enabled)
Active: active (running) since Tue 2021-10-19 08:37:03 UTC; 3s ago
That's it! You have successfully installed Telegraf on Ubuntu Server Latest. You can now configure Telegraf to gather metrics from various sources using the configuration file.
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!
