How to Install Grafana TIG stack Ubuntu

Note: Tested and Validated Procedure on 12th October 2023

A Grafana TIG stack is a technology stack that stands for Telegraf, InfluxDB, and Grafana. It is commonly used for monitoring and visualizing time-series data in real-time.

Telegraf is an open-source data collection agent that collects and sends metrics and events to InfluxDB. InfluxDB is a time-series database that stores and manages the data collected by Telegraf. Grafana is a data visualization and monitoring platform that connects to InfluxDB to provide real-time visualizations and dashboards for the collected data.

Together, these three components create a powerful real-time platform for monitoring and visualizing time-series data. The TIG stack is particularly popular in DevOps and IT operations teams as it allows for monitoring various infrastructure components and application performance metrics.

In this demo, I will install the Grafana server on Ubuntu. Specifically, this will be a TIG stack, you will learn how to Set Up Grafana Monitoring Dashboards with Telegraf and InfluxDB Backend.

The power of a TIG Stack: Monitor Your Data Sources with Ease

The grafana tig stack is one of the most popular and powerful open-source tools available for monitoring a wide panel of data sources. This stack includes Telegraf, InfluxDB, and Grafana and can help streamline your data collection, aggregation, and reporting processes.

What is Telegraf?

Telegraf is a server agent used for collecting and aggregating data and reporting metrics. It is a highly scalable application that allows users to easily access metrics from the system. With Telegraf, you can monitor, store, and analyze data from any source in any format.

What is InfluxDB?

InfluxDB is an open-source database that stores data and exposes it to the Grafana dashboard. It can automate sensors and devices in real-time and provide insights into the performance of your systems and applications. With InfluxDB, you can quickly and easily access and monitor your data sources, ensuring that you have the data you need to make informed decisions.

What is Grafana?

Grafana is an open-source data visualization tool that supports various time series data stores, including Prometheus, Elasticsearch, and InfluxDB. It helps create beautiful, interactive dashboards for easy data exploration and troubleshooting. With Grafana, you can quickly and easily visualize your data sources in real-time.

You can easily monitor your data sources by leveraging the powerful grafana tig stack. With Telegraf, Grafana, and InfluxDB, you can quickly and easily collect, aggregate, and analyze data from any source. With the TIG stack, you can be confident that your data is secure, accurate, and up-to-date.

How to Install a TIG Stack

Ensure that you have a Linux Ubuntu 22.04 server available.

Step 1 – Update Ubuntu Base System

Type the following to update the base repos

apt update -y

You may want to take the time to update your operating system at this point (optional)

apt upgrade -y

Now prep the server to install all the required software

apt install gnupg2 software-properties-common -y

Step 2 – Install Grafana

This stage will install all the required packages for Grafana. If you hit an error here, its likely the gpg key has been rotated by Grafana. Check out this site for more information.

wget -q -O - https://apt.grafana.com/gpg.key | gpg --dearmor > /etc/apt/keyrings/grafana.gpg

echo "deb [signed-by=/usr/share/keyrings/grafana.gpg] https://packages.grafana.com/oss/deb stable main" | sudo tee -a /etc/apt/sources.list.d/grafana.list

Now update your repo’s

apt update -y

You will notice that apt is now looking at the grafana repo

apt install grafana -y
systemctl start grafana-server
systemctl enable grafana-server

You can check the status of the Grafana service using

systemctl status grafana-server

Step 3 – Install InfluxDB

Now add the influxDB repository to the Ubuntu server. This repo is not available by default and must be added manually.

Use this one-liner to install everything you need.

You can check the latest versions of InfluxDB on the official website.

wget -q https://repos.influxdata.com/influxdata-archive_compat.key
echo '393e8779c89ac8d958f81f942f9ad7fb82a25e133faddaf92e15b16e6ac9ce4c influxdata-archive_compat.key' | sha256sum -c && cat influxdata-archive_compat.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg > /dev/null
echo 'deb [signed-by=/etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg] https://repos.influxdata.com/debian stable main' | sudo tee /etc/apt/sources.list.d/influxdata.list

apt-get update && sudo apt-get install influxdb2
apt-get install influxdb -y

Now start and enable InfluxDB

systemctl enable --now influxdb
systemctl start influxdb

You can check the status of the InfluxDB service using

systemctl status influxdb

Step 4 – Configure InfluxDB

Login into the Influx shell by typing

influx

Now create a database for Telegraf

create database telegrafdb;
create user telegraf with password 'my-super-strong-password';
grant all on telegrafdb to telegraf;

You can check everything is configured by typing

show databases

Now exit from InfluxDB shell

exit

Step 5 – Install Telegraf

This one-liner will install the SHA256-verified version of Telegraf

wget -q https://repos.influxdata.com/influxdata-archive_compat.key
echo '393e8779c89ac8d958f81f942f9ad7fb82a25e133faddaf92e15b16e6ac9ce4c influxdata-archive_compat.key' | sha256sum -c && cat influxdata-archive_compat.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg > /dev/null
echo 'deb [signed-by=/etc/apt/trusted.gpg.d/influxdata-archive_compat.gpg] https://repos.influxdata.com/debian stable main' | sudo tee /etc/apt/sources.list.d/influxdata.list

sudo apt-get update && sudo apt-get install telegraf

Create a default telegraf config

telegraf config -input-filter cpu:mem:swap:system:processes:disk -output-filter influxdb > /etc/telegraf/telegraf.conf

Add your influxDB database configuration by using nano, vim, or vi.

Make sure your find the correct section in the telegraf.conf file

nano /etc/telegraf/telegraf.conf

[[outputs.influxdb]]
urls = ["http://127.0.0.1:8086"]
database = "telegrafdb"
username = "telegraf"
password = "my-super-strong-password"

Now start and enable the Telegraf service

systemctl enable --now telegraf
systemctl start telegraf

You can check the status of the Telegraf service using

systemctl status telegraf

Step 6 – Setup Grafana Data Source

Next, you will need to access the Grafana dashboard and add a data source to display the InfluxDB and Telegraf metrics.

You can access the Grafana Dashboard using the URL http://your-server-ip:3000/. You should see the Grafana login page:

Provide default username as admin and password as admin then click on the login button. You should see the password reset screen:

Note: Since Grafana version 7.2.2, many users have reported the default admin and password does not work. If this is the case, type the following on your server command prompt:

grafana-cli admin reset-admin-password mynewpassword

Add your new password and click the Submit button to change the default password. You should see the Grafana dashboard on the following page:

To add the data source, click on Add your first data source. You should see the following screen:

Search for InfluxDB and click on the Select button. You should see the following page:

Set the name of the InfluxDB, select InfluxQL in Query Language, define the URL of the InfluxDB data source, provide InfluxDB database details, and click on the Save & Test button. Once the test is successful, you should see the following page:

Step 7 – Setup Grafana Dashboard

At this point, we have added InfluxDB as a data source to the Grafana server. Next, you will need to import the Grafana dashboard.

On the Grafana Dashboard, click on the ‘+’ menu on the left panel and click the ‘Import‘ button. You should see the following page:

Type Grafana ID 5955 and click on the Load button to load the dashboard as shown below.

Select InfluxDB and click on the Import button. You should see the Grafana Dashboard showing the system metrics collected by the Telegraf agent:
