We have looked into Prometheus and how to install both the probes as well as the monitoring “gateway” on both Windows and Linux. But for anyone that has looked at the Prometheus monitoring portal http://<ip address>:9100 will know that is is a but “undercooked” and not as user friendly. So today we solve that with another (amazing) open-source tool called Grafana.
What Is Grafana?
Grafana is an open-source data visualization and monitoring tool. It enables you to create dynamic and interactive dashboards to monitor the health and performance of your systems. It transforms raw data into beautiful, customizable graphs, charts, and alerts, making complex data easy to understand.
With Grafana, you can:
- Monitor system performance over time.
- Track application behavior.
- Set up alerts to notify you about system anomalies.
How Does Grafana Work?
Grafana doesn’t store data on its own. Instead, it connects to various data sources and visualizes the data they provide. Once connected, you can create dashboards to represent the data in ways that suit your needs.
Popular Features of Grafana
- Multi-data source support: Integrates with numerous tools and databases.
- Custom dashboards: Create tailored dashboards with a drag-and-drop interface.
- Alerts: Configure alerts based on threshold values or other conditions.
Grafana and Prometheus: A Perfect Match
Prometheus is a powerful monitoring system and time-series database. It scrapes metrics from your systems or applications and stores them in its database. While Prometheus provides a web interface for viewing these metrics, its capabilities are limited when it comes to visualization.
This is where Grafana shines. By connecting Grafana to Prometheus, you get:
- Enhanced Visuals: Grafana allows you to create advanced and visually appealing dashboards.
- Advanced Querying: Use Prometheus’ data with Grafana’s query editor for deeper insights.
- Better Alerts: Set up custom alerts through Grafana’s notification channels.
Examples of Software Grafana Can Integrate With
Grafana supports a wide range of data sources, including:
- Prometheus: For time-series monitoring data.
- Elasticsearch: For log analytics.
- MySQL/PostgreSQL: For database metrics.
- Loki: For log aggregation.
- AWS CloudWatch: For cloud monitoring.
- Google BigQuery: For large-scale data analysis.
How to Install Grafana
If the install instructions seems too tedious, keep an eye out for our Grafana Cloud article, using the cloud and not a local install.

Comparing Prometheus and Grafana
| Feature | Prometheus | Grafana |
|---|---|---|
| Visualization | Basic charts and tables | Advanced dashboards and visuals |
| Alerts | Simple alerts | Custom, multi-channel alerts |
| Ease of Use | CLI and basic web UI | Intuitive web-based UI |
| Data Sources | Only Prometheus data | Integrates with multiple sources |
| Auto Refresh | No | Yes |
Why Use Grafana with Prometheus?
While Prometheus is great at collecting and storing metrics, it lacks advanced visualization tools. Grafana bridges this gap, making it easier to interpret and act on the data Prometheus collects.
Conclusion
Grafana is a game-changer for monitoring and visualizing your system’s performance. Paired with Prometheus, it offers a seamless way to track metrics, analyze trends, and gain insights. With its wide range of integrations, Grafana empowers you to centralize your monitoring efforts in one place.
Whether you’re a system administrator, developer, or hobbyist, installing Grafana and pairing it with Prometheus will elevate your monitoring capabilities and help you make informed decisions based on your data. Why settle for basic graphs when you can have a full-fledged dashboard? Start your journey with Grafana today!
