Grafana is an open-source analytics and visualization platform designed to create dynamic, interactive dashboards for monitoring and analyzing data from various sources.
What is Grafana?
Grafana is a versatile platform that allows users to visualize metrics, logs, and traces across diverse data sources. It supports real-time monitoring and long-term analysis, making it a preferred tool for DevOps teams, IT administrators, and anyone managing large-scale systems. Grafana is highly extensible, offering plugins, alerting mechanisms, and integrations with a wide range of technologies. It excels in presenting complex data sets in an intuitive, actionable format.
Main Features
Grafana stands out due to its flexibility and wide-ranging functionality, allowing users to adapt it to their specific needs.
Key features include:
- Multi-Source Support: Connects to databases like Prometheus, InfluxDB, MySQL, PostgreSQL, Elasticsearch, and cloud services like AWS, Azure, and Google Cloud.
- Customizable Dashboards: Build and design dashboards with panels, graphs, and tables tailored to any use case.
