Graph Panel Tutorial in Grafana

Introduction to Graph Panel

The Graph Panel in Grafana is a powerful visualization tool that allows users to display time-series data in a graphical format. It is widely used for monitoring metrics over time, allowing for quick analysis and decision-making. This tutorial will guide you through the process of creating and customizing a Graph Panel from scratch.

Setting Up Your Grafana Environment

Before you can create a Graph Panel, you need to have Grafana installed and running. You can either install it locally or use a cloud-based Grafana service.

Follow these steps to get started:

1. Download and install Grafana from the official site.
2. Start the Grafana server. Typically, you can do this via the command line with systemctl start grafana-server.
3. Access Grafana by navigating to http://localhost:3000 in your web browser.
4. Log in using default credentials: username admin and password admin.

Creating a New Dashboard

To add a Graph Panel, you first need to create a new dashboard:

1. Click on the “+” icon in the left sidebar.
2. Select “Dashboard” from the dropdown menu.
3. Click on “Add new panel” to start configuring your Graph Panel.

Adding a Graph Panel

Now that you have a new dashboard, it’s time to add a Graph Panel:

1. In the panel editor, select “Graph” from the visualization options.
2. Add your data source. This can be anything from Prometheus to InfluxDB.
3. Write your query to fetch the desired data. For example, if you're using Prometheus, you might use a query like:

rate(http_requests_total[5m])

4. Click “Run Query” to see a preview of your data.

Customizing Your Graph Panel

Grafana offers a wide range of customization options for Graph Panels:

• Axes: You can customize the X and Y axes. Click on the “Axes” tab in the panel editor to set labels, scales, and units.
• Legend: Enable or disable the legend to show data series names and values.
• Display options: Adjust the line width, fill, point size, and more in the “Display” tab.

1. Click on the “Save” icon in the top right corner of the dashboard.
2. Give your dashboard a name and click “Save.”
3. To share your dashboard, click on the “Share” icon and choose the sharing options you prefer.
