Grafana is an open source visualization tool with support for many databases, including Graphite, InfluxDB, Prometheus, and Elasticsearch. It is designed for analyzing and visualizing metrics such as system CPU, memory, disk and I/O utilization. Grafana does not collect data, but allows you to connect to data sources like Prometheus or Graphite. It is a popular solution for bringing together and visualizing disparate data sources.
In Grafana, users can create versatile dashboards with graph, singlestat, table, heatmap, and freetext panels. Dashboards and panels are fully customizable and can be annotated to track specific events. These dashboards can be used for everything from identifying anomalies and debugging applications, to gaining actionable insights on user behavior.
