Grafana
Open-source analytics and visualization platform
From Wikipedia, the free encyclopedia
Grafana is an open-source analytics and visualization web application. It connects to time series databases and other data sources, allowing users to build dashboards that display metrics, logs, and traces. Grafana supports data sources including Prometheus, Graphite, InfluxDB, Elasticsearch, PostgreSQL, and MySQL.[4]

Torkel Odegaard released Grafana in January 2014 as an outgrowth of work at Orbitz. The user interface was originally based on version 3 of Kibana.[5] The company behind the project, initially named Raintank, rebranded as Grafana Labs and has raised over $500 million in venture capital funding, reaching a $6 billion valuation in 2024.[6]
Since 2021, Grafana has been licensed under the AGPLv3 (previously Apache 2.0).[3] A commercial Grafana Enterprise edition adds features including LDAP team synchronization, data source permissions, and reporting.[7]
History
Grafana was first released in January 2014, initially targeting Graphite and InfluxDB as data sources. It later added support for relational databases including MySQL, PostgreSQL, and Microsoft SQL Server.[8]
Grafana Labs was founded in 2014 as Raintank and later adopted the Grafana name.[9] The company raised $24 million in Series A funding in 2019,[10] $50 million in Series B in 2020,[11] $220 million in Series C in 2021 (at a $3 billion valuation),[12] and $270 million in 2024 at a $6 billion valuation.[6]
Grafana Labs acquired several companies to expand its observability stack: Kausal (2018),[13] k6 (2021, load testing),[14] Pyroscope (2023, continuous profiling),[15] Asserts.ai (2023, AI-assisted observability),[16] and TailCtrl (2024, trace sampling).[17]
Architecture
Grafana's backend is written in Go and its frontend in TypeScript using React.[2] The application runs as a single binary that serves a web interface and connects to external data sources through a plugin system. Plugins fall into three categories: data source plugins (for querying backends), panel plugins (for visualization types), and app plugins (for bundled functionality).[7]
Grafana does not store metrics data itself. It queries external data sources at render time and can combine data from multiple sources in a single dashboard. Built-in data source support includes Prometheus, Graphite, InfluxDB, Elasticsearch, OpenSearch, Loki, MySQL, PostgreSQL, and Splunk.[4]
Dashboards are defined as JSON documents and can be provisioned from files, version-controlled, and shared via Grafana's public dashboard library. Alerting rules can be defined against any data source, with notifications routed to email, Slack, PagerDuty, and other channels.[7]
LGTM stack
Grafana Labs develops a set of open-source backends that are often deployed together as the "LGTM stack" (Loki, Grafana, Tempo, Mimir):[18]
- Loki -- a log aggregation system, first released in 2019, that indexes metadata rather than full log text.[19]
- Mimir -- a horizontally scalable, Prometheus-compatible metrics backend, released in 2022 as a replacement for Cortex.[20]
- Tempo -- a distributed tracing backend, released in 2021.[21]
- Pyroscope -- a continuous profiling backend, released in 2023.[22]
