What is Grafana?
A tool for turning metrics, logs and traces into dashboards and alerts.
In plain English
Grafana connects to data sources such as Prometheus and shows their data as graphs and tables on shared dashboards. It does not collect the data itself. Teams use it to watch the health of systems and to set up alerts.
Example
A dashboard shows request rate, error rate and response time for a service, with a panel that turns red when errors climb.
Easy to confuse with
- Prometheus: Grafana displays data. Prometheus is one of the places that data is collected and stored.
