First released in 2014, Grafana is a multi-platform open source analytics and interactive visualization web application. It provides charts, graphs, and alerts for the web when connected to supported data sources. It is expandable through a plug-in system. End users can create complex monitoring dashboards using interactive query builders. As a visualisation tool, Grafana is a popular component in monitoring stacks, often used in combination with time series databases such as InfluxDB, Prometheus and Graphite; monitoring platforms such as Sensu, Icinga, Checkmk, Zabbix, Netdata, and PRTG; SIEMs such as Elasticsearch and Splunk; and other data sources. Grafana was first released in 2014 by Torkel Ödegaard as an offshoot of a project at Orbitz; it targeted time series databases such as InfluxDB, OpenTSDB, and Prometheus but evolved to support relational sources such as MySQL, PostgreSQL and Microsoft SQL Server. In 2019, Grafana Labs secured $24 million in Series A funding. Platforms like PayPal, ebay, Staples, Intel, Vimeo, and TED have used this application.
