Why Grafana?

​1. Dashboards that anyone can use​

​Not only do Grafana dashboards give insightful meaning to data collected from numerous sources, but you can also share the dashboards you create with other team members, allowing you to explore the data together. With Grafana, anyone can create and share dynamic dashboards to foster collaboration and transparency.​

​2. Flexibility and versatility​

​Translate and transform any of your data into flexible and versatile dashboards. Unlike other tools, Grafana allows you to build dashboards specifically for you and your team.​

With advanced querying and transformation capabilities, you can customize your panels to create visualizations that are actually helpful for you.​

3. Unify your data, not your database​

​Grafana doesn’t require you to ingest data to a backend store or vendor database. Instead, Grafana takes a unique approach to providing a “single-pane-of-glass” by unifying your existing data, wherever it lives.​

4. Data everyone can see​

​Grafana was built on the principle that data should be accessible to everyone in your organization, not just the single Ops person.​

By democratizing data, Grafana helps to facilitate a culture where data can easily be used and accessed by the people that need it.​
