Documentation Grafana Alloy Reference Configuration blocks export

export block

export is an optional configuration block used to specify an emitted value of a custom component. export blocks must be given a label which determine the name of the export.

The export block may only be specified inside the definition of a declare block.

Example

alloy Copy

export "ARGUMENT_NAME" {
  value = ARGUMENT_VALUE
}

Arguments

The following arguments are supported:

The value argument determines what the value of the export is. To expose an exported field of another component, set value to an expression that references that exported value.

Exported fields

The export block doesn’t export any fields.

Example

This example creates a custom component where the output of discovering Kubernetes pods and nodes are exposed to the user:

alloy Copy

declare "pods_and_nodes" {
  discovery.kubernetes "pods" {
    role = "pod"
  }

  discovery.kubernetes "nodes" {
    role = "nodes"
  }

  export "kubernetes_resources" {
    value = concat(
      discovery.kubernetes.pods.targets,
      discovery.kubernetes.nodes.targets,
    )
  }
}
