Grafana Enterprise data source plugins are a key feature of Grafana, enhancing its role as an open and extensible observability platform by allowing users to connect and visualize data from various external systems through Grafana dashboards. These plugins enable users to view and correlate metrics, logs, and traces from multiple sources without data migration, thereby improving troubleshooting and reducing Mean Time to Resolution. Grafana Enterprise data sources, built and supported by Grafana Labs, are available in Grafana Enterprise and Grafana Cloud, with a variety of pricing models depending on the tier and number of active users. The plugins support connections to proprietary tools and platforms like Splunk, Dynatrace, and Databricks, providing a seamless user experience through easy query building and data filtering. Installation and configuration are straightforward, especially in Grafana Cloud, where a one-click installation process is available. Users can access additional resources and documentation to learn more about these plugins, with options for free-tier access in Grafana Cloud for a limited number of users.
