What is Grafana?
Overview, features, and comparison with other visualization tools
Overview
Grafana is an open-source dashboard tool for visualizing and monitoring time-series data.
It connects to various data sources such as Prometheus, Loki, InfluxDB, Elasticsearch, MySQL, and more, enabling intuitive real-time data analysis.
With its integrated dashboard management, Grafana is widely used in DevOps, infrastructure operations, and application monitoring.
What is Grafana?
Grafana is fundamentally a “UI platform for visualizing time-series data.”
However, it has evolved beyond a simple visualization tool into a powerful solution that encompasses monitoring, alerting, data exploration, and sharing capabilities.
Key Features Summary
| Feature | Description |
|---|---|
| Visualization | Utilizes various panels (graphs, tables, gauges, etc.) to represent data |
| Data Source Connection | Supports dozens of sources including Prometheus, Loki, Graphite, InfluxDB, Elasticsearch |
| Alerting | Sends notifications to Slack, Teams, Webhook, etc., when specific conditions are met |
| Dashboard Sharing | Optimized for collaboration with URL, snapshot, and read-only link options |
| User/Permission Management | Configurable view/edit permissions per user (supports LDAP, OAuth authentication) |
| Data Exploration | Query builder + explorer functionality for real-time log and metric queries |
| Plugin Support | Expandable with various community plugins (data sources, panels, etc.) |
