How to Link Prometheus as a Data Source in Grafana on Amazon Linux 2023

If you’ve set up Prometheus and Grafana on Amazon Linux 2023, the next step is to connect Prometheus as a data source inside Grafana. This allows you to visualize metrics in beautiful dashboards and make your monitoring stack complete.

In this guide, I’ll show you step-by-step how to integrate Prometheus with Grafana.

✅ Step 1: Verify Prometheus is Running

Prometheus usually runs on port 9090.

Open your browser and check:

http://<your-ec2-public-ip>:9090

If the Prometheus web UI opens, it’s running fine.

✅ Step 2: Access Grafana

Grafana runs on port 3000.

Visit:

http://<your-ec2-public-ip>:3000

Login using:

• Username: admin
• Password: admin (You’ll be asked to change this the first time)

✅ Step 3: Add Prometheus as a Data Source

1. In Grafana, click on the left menu:
   Connections → Data sources → Add data source
2. Select Prometheus.
3. Under HTTP settings, set the URL:
   • If Grafana and Prometheus are on the same server: http://localhost:9090
   • If they are on different servers: http://<prometheus-ec2-ip>:9090
4. Leave other options as the default.
5. Click Save & Test.
   Grafana should confirm: “Data source is working.”

✅ Step 4: Import Dashboards

To start visualizing metrics:

• Go to Dashboards → Create → Import
• You can use ready-made dashboards from Grafana’s Dashboard Library
  For example:
  • Node Exporter Full (ID: 1860) → Great for monitoring Linux servers

🎯 Conclusion

By linking Prometheus as a data source in Grafana, you unlock the power of real-time monitoring with visually rich dashboards. This setup is a must-have for any DevOps monitoring stack on AWS.

With Grafana + Prometheus, you’ll be able to:

• Track server health
• Monitor application performance
• Set up alerts for proactive issue resolution

💡 Pro Tip: Combine Prometheus with Node Exporter or custom app metrics to make your Grafana dashboards even more insightful.
