Grafana Agent Flow

Grafana Agent Flow is a component-based revision of Grafana Agent with a focus on ease-of-use, debuggability, and ability to adapt to the needs of power users.

Components allow for reusability, composability, and focus on a single task.

  • Reusability allows for the output of components to be reused as the input for multiple other components.
  • Composability allows for components to be chained together to form a pipeline.
  • Single task means the scope of a component is limited to one narrow task and thus has fewer side effects.


  • Write declarative configurations with a Terraform-inspired configuration language.
  • Declare components to configure parts of a pipeline.
  • Use expressions to bind components together to build a programmable pipeline.
  • Includes a UI for debugging the state of a pipeline.


// Discover Kubernetes pods to collect metrics from
discovery.kubernetes "pods" {
  role = "pod"

// Scrape metrics from Kubernetes pods and send to a prometheus.remote_write
// component.
prometheus.scrape "default" {
  targets    = discovery.kubernetes.pods.targets
  forward_to = [prometheus.remote_write.default.receiver]

// Get an API key from disk.
local.file "apikey" {
  filename  = "/var/data/my-api-key.txt"
  is_secret = true

// Collect and send metrics to a Prometheus remote_write endpoint.
prometheus.remote_write "default" {
  endpoint {
    url = "http://localhost:9009/api/prom/push"

    basic_auth {
      username = "MY_USERNAME"
      password = local.file.apikey.content

Grafana Agent configuration generator

The Grafana Agent configuration generator will help you get a head start on creating flow code.

Note: This feature is experimental, and it doesn’t support all River components.
