Stat Panel Tutorial in Grafana

Introduction

The Stat Panel in Grafana is a powerful visualization used to display a single numeric value. This panel is ideal for showcasing key performance indicators (KPIs) or any critical metrics that need to be monitored in real-time.

Creating a Stat Panel

To create a Stat Panel, follow these steps:

  1. Log in to your Grafana dashboard.
  2. Select the dashboard where you want to add the Stat Panel.
  3. Click on the “Add Panel” button.
  4. Choose the “Stat” visualization type from the list.

Your Stat Panel is now created, but you will need to configure it to display your desired data.

Configuring the Stat Panel

After creating the Stat Panel, you can customize it by following these steps:

  1. In the panel editor, go to the “Query” tab.
  2. Choose your data source from the dropdown.
  3. Write the query to fetch the desired metric. For example:

SELECT COUNT(*) AS total_requests FROM requests WHERE status = 'success'

This query fetches the total number of successful requests.

Customizing Appearance

You can further customize the appearance of your Stat Panel:

  • Change the title in the “Panel” tab.
  • Adjust the thresholds under the “Field” tab to change colors based on value ranges.
  • Modify the unit of measure (e.g., none, percentage, bytes) to suit your data type.

For example, if you set thresholds for the total requests, you might want to color code them as follows:

Thresholds: 0 - 50 = red, 51 - 100 = yellow, 101+ = green

Example Use Case

Imagine you are monitoring an e-commerce website. You want to display the total number of sales in real-time:

  1. Set up your data source to connect to your sales database.
  2. Use the following query:

SELECT COUNT(*) AS total_sales FROM sales WHERE sale_date = CURRENT_DATE

This will display the total number of sales for the current day on your Stat Panel.

Conclusion

The Stat Panel in Grafana is an effective way to visualize key metrics succinctly. By following the steps outlined in this tutorial, you can create and customize a Stat Panel to suit your monitoring needs. Experiment with different queries and visual settings to optimize your dashboard!
