How to Install TIG Stack (Telegraf, InfluxDB, and Grafana) on Rocky Linux

Introduction

The TIG Stack is a powerful monitoring solution that includes Telegraf for collecting metrics, InfluxDB for storing time-series data, and Grafana for visualizing the data. This tutorial will guide you through the process of installing the TIG Stack on Rocky Linux.

Prerequisites

Before you begin, ensure you have:

1. A Rocky Linux system
2. Root or sudo privileges

Step 1: Install InfluxDB

Add the InfluxData repository:

sudo dnf install -y https://repos.influxdata.com/influxdb-release-1.rpm

Install InfluxDB:

sudo dnf install -y influxdb

Start and enable the InfluxDB service:

sudo systemctl start influxdb
sudo systemctl enable influxdb

Step 2: Install Telegraf

Add the InfluxData repository:

sudo dnf install -y https://repos.influxdata.com/telegraf-release-1.rpm

Install Telegraf:

sudo dnf install -y telegraf

Start and enable the Telegraf service:

sudo systemctl start telegraf
sudo systemctl enable telegraf

Step 3: Install Grafana

Add the Grafana repository:

sudo dnf install -y https://packages.grafana.com/oss/rpm/grafana-8.1.2-1.x86_64.rpm

Install Grafana:

sudo dnf install -y grafana

Start and enable the Grafana service:

sudo systemctl start grafana-server
sudo systemctl enable grafana-server

Step 4: Configure Grafana

Open a web browser and navigate to http://localhost:3000.

Login with the default username and password (admin/admin).

Change the password and configure Grafana as needed.

Step 5: Configure Data Source

Add InfluxDB as a data source in Grafana:

• Go to Configuration > Data Sources > Add data source.
• Choose InfluxDB.
• Enter the InfluxDB URL (http://localhost:8086) and database details.
• Save and test the data source.

Conclusion

Congratulations! You have successfully installed the TIG Stack (Telegraf, InfluxDB, and Grafana) on Rocky Linux. You can now start collecting, storing, and visualizing metrics using this powerful monitoring solution.
