Grafana

Grafana is an open-source web application specializing in real-time time-series graph visualization. Written in JavaScript and Go, Grafana features a web-based dashboard which is composed of pluggable, drag-and-drop-capable panels. It can visualize various graph metrics based on time-series measurements and custom style templates. Out of box, Grafana can be integrated with a number of time-series data storage backends such as InfluxDB, Graphite, OpenTSDB, KairosDB, Prometheus and Elasticsearch. The built-in query editor allows users to compose custom queries on one or more instances of time-series databases distributed across multiple nodes. Grafana comes with its own backend server with full HTTP API and authentication support.
