Grafana Agent Flow is an experimental feature introduced in the Grafana Agent v0.28.0 release, designed to provide a more intuitive and powerful way to configure, run, and debug Grafana Agent. This new feature aims to simplify the learning curve for new users while empowering experienced users to create complex workflows using programmable pipelines composed of small, reusable components. Built on River, a Terraform-inspired declarative language, Flow allows dynamic configuration through expressions and utility functions, enabling components to emit output values that bind together in a pipeline. This event-driven evaluation system facilitates real-time updates and immediate feedback on configuration changes, enhancing the user experience beyond the limitations of the static Agent mode. Currently focused on Prometheus metrics pipelines, Flow is set to expand with support for logs, traces, and integration with OpenTelemetry Collector components, promising a more robust future for Grafana Agent users.
