Grafana (original) (raw)

Last Updated : 1 Apr, 2026

Grafana is an open-source observability platform that visualizes real-time data from multiple external sources without storing it. It acts as a bridge between telemetry and monitoring workflows, helping teams understand system performance and respond faster to incidents.

• Connects with tools like Prometheus, Elasticsearch, and MySQL for unified data visualization.
• Offers interactive dashboards, alerting, plugins, and RBAC for secure and scalable monitoring.
• Commonly paired with Prometheus to track infrastructure health, latency, and anomalies.
• Supports diverse use cases including infrastructure, application performance, business metrics, and cloud monitoring.

Grafana Working & Architecture Flow

Grafana acts as a visualization layer between your data sources and your monitoring workflows.

Grafana Working

1. Data is collected by monitoring tools (e.g., Prometheus).
2. Grafana queries these sources in real time.
3. Results are displayed through dashboards.
4. Alerts are triggered when thresholds are exceeded.

Grafana also integrates seamlessly with:

• **Metrics: Prometheus, InfluxDB
• **Logs: Loki, Elasticsearch
• **Traces: Tempo, Jaeger

This unified approach provides complete visibility across your systems.

• Running it as a service ensures that Grafana operates continuously in the background.
• It also enables Grafana to start automatically whenever your system boots up.

**Access Grafana Web Interface:

• By default, Grafana runs on port 3000 after the initial setup.
• Open a web browser and visit the default URL to access the Grafana web interface.
• Log in using the default credentials, after which you will be prompted to change your password.

**Add Data Sources:

• After logging in, you need to add data sources to Grafana to begin visualizing metrics.
• Grafana supports multiple data sources such as Prometheus, MySQL, and PostgreSQL, along with many other integrations.
• Navigate to the settings section to add and configure a data source by providing details like the server address and login credentials.

**Create Your First Dashboard:

• After connecting your data sources, you can start designing dashboards within Grafana.
• Grafana’s interface makes it easy to create dashboards and visualize your data effectively.
• Add panels to monitor different metrics, choosing from visualization options such as graphs, tables, and heatmaps.

**Set Up Alerts:

• Grafana enables users to set up alerts to monitor specific conditions.
• Alerts trigger notifications when defined metrics exceed or fall below specified threshold values.
• You can create alert rules within the panel settings and configure notification channels to receive alerts.

**Secure Grafana:

• Securing Grafana is essential for maintaining a safe deployment environment.
• Enable HTTPS to encrypt data in transit and protect sensitive information.
• Implement authentication methods such as LDAP or OAuth, and configure Role-Based Access Control (RBAC) to limit access to data and features.

Grafana Management Solutions
