README

Grafana Agent is a vendor-neutral, batteries-included telemetry collector with configuration inspired by Terraform. It is designed to be flexible, performant, and compatible with multiple ecosystems such as Prometheus and OpenTelemetry.

Grafana Agent is based around components. Components are wired together to form programmable observability pipelines for telemetry collection, processing, and delivery.

NOTE: This page focuses mainly on "Flow mode," the Terraform-inspired revision of Grafana Agent.

Grafana Agent can collect, transform, and send data to:

• The Prometheus ecosystem
• The OpenTelemetry ecosystem
• The Grafana open source ecosystem (Loki, Grafana, Tempo, Mimir, Phlare)

Why use Grafana Agent?

• Vendor-neutral: Fully compatible with the Prometheus, OpenTelemetry, and Grafana open source ecosystems.
• Every signal: Collect telemetry data for metrics, logs, traces, and continuous profiles.
• Scalable: Deploy on any number of machines to collect millions of active series and terabytes of logs.
• Battle-tested: Grafana Agent extends the existing battle-tested code from the Prometheus and OpenTelemetry Collector projects.
• Powerful: Write programmable pipelines with ease, and debug them using a built-in UI.
• Batteries included: Integrate with systems like MySQL, Kubernetes, and Apache to get telemetry that's immediately useful.

Getting started

Check out our documentation to see:

• Installation instructions for Grafana Agent Flow
• Details about Grafana Agent Flow
• Steps for Getting started with Grafana Agent Flow
• The list of Grafana Agent Flow Components

Example

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

// Collect metrics from Kubernetes pods.
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
}

// 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
    }
  }
}

We maintain an example Docker Compose environment that can be used to launch dependencies to play with Grafana Agent locally.

Release cadence

A new minor release is planned every six weeks. You can use the list of Milestones to see what maintainers are planning on working on for a given release cycle.

Both the release cadence and the items assigned to a milestone are best-effort: releases may be moved forwards or backwards if needed, and items may be moved to a different milestone or removed entirely. The planned release dates for future minor releases do not change if one minor release is moved.

Patch and security releases may be created at any time.
