Using MySQL with Grafana as a Data Source
Hello! I'm Yuvraj. I'm a Computer Science Student. I love to learn, create, and explore new things. I am currently doing a Bachelor of Computer Science from the University of Delhi.
Grafana rocks.
Now that we understand the basics of Kafka producers and consumers, let's build a more realistic example that shows how Kafka can be used in a real-world scenario. We'll create a simple order processing system with these components: Order Service: C...
Now that we've created a producer that sends messages to Kafka, let's create a consumer that reads those messages. A consumer is an application that subscribes to Kafka topics and processes the messages. Setting Up the Project First, let's set up our...
Now that we understand the basic concepts of Kafka, let's create our first producer. A producer is an application that sends messages to Kafka topics. Setting Up the Project First, let's set up our Node.js project: Create a package.json file in the ...

Grafana is widely known for its powerful data visualization capabilities, often used in conjunction with Prometheus for monitoring and metrics collection. However, many users wonder if it is possible to use Grafana without Prometheus. The answer is yes! Grafana's versatility allows it to support a wide range of data sources, making it a flexible tool for various use cases.
In this article, we will explore the possibility and benefits of using Grafana without Prometheus, and provide a step-by-step guide on setting up Grafana with MySQL as the data source.
Grafana is an open-source platform for monitoring and observability that excels in visualizing data from a variety of sources. It offers a highly customizable dashboarding experience, allowing users to create, explore, and share dashboards that display data from different systems.
Grafana supports numerous data sources out-of-the-box, including:
MySQL
InfluxDB
Elasticsearch
PostgreSQL
Prometheus
Graphite
Cloudwatch
Azure Monitor
These integrations enable users to visualize data from various databases and services, making Grafana a versatile tool for many applications.
Flexibility in Data Source Selection: Grafana's support for multiple data sources means you can choose the one that best fits your needs, whether it's a SQL database, a time-series database, or a cloud service.
Simplified Architecture: By using Grafana with a data source like MySQL, you can simplify your monitoring architecture, which might be beneficial for specific use cases.
Cost Savings: Depending on your requirements, using a single data source can reduce complexity and costs associated with managing multiple monitoring tools.
Let's dive into a practical example of setting up Grafana with MySQL as the data source.
Step 1: Install Grafana
Download and install Grafana from the official website. Follow the installation instructions for your operating system.
Step 2: Set Up MySQL and Create a Sample Database
Install MySQL on your system if it's not already installed. Create a sample database and table for storing your data:
CREATE DATABASE sample_db;
USE sample_db;
CREATE TABLE metrics (
id INT AUTO_INCREMENT PRIMARY KEY,
metric_name VARCHAR(255) NOT NULL,
value FLOAT NOT NULL,
timestamp DATETIME DEFAULT CURRENT_TIMESTAMP
);
INSERT INTO metrics (metric_name, value) VALUES ('cpu_usage', 23.5), ('memory_usage', 55.1);
Step 3: Configure Grafana to Connect to MySQL
Open Grafana in your browser (default URL is http://localhost:3000).
Log in with the default credentials (admin/admin, you an read detailed guide to login here).
Select MySQL from the list of data sources.
Enter the necessary connection details (e.g., host, database name, user, and password) and click Save & Test to verify the connection.
Host URL will be likely localhost:3306
Database Name: sample_db
Add your database username and password in the authentication.
Step 4: Create a Simple Dashboard Using MySQL Data
Select your MySQL data source.
Write a simple SQL query to fetch data from your sample table:
SELECT
UNIX_TIMESTAMP(timestamp) as time_sec,
value as value,
metric_name as metric
FROM metrics
Customize the visualization as needed and save your dashboard.
Many organizations leverage Grafana with data sources other than Prometheus to meet specific needs:
Web Application Monitoring: Using MySQL or PostgreSQL to track user interactions and performance metrics.
Business Analytics: Visualizing data from SQL databases to monitor KPIs and other business metrics.
IoT Data Visualization: Utilizing InfluxDB to collect and visualize sensor data.
Grafana is a versatile tool that can be used with a variety of data sources beyond Prometheus. This flexibility allows users to tailor their monitoring and visualization setup to their specific needs, simplifying architecture and potentially reducing costs.
