Grafana Alloy is an open source OpenTelemetry Collector distribution with built-in Prometheus pipelines and support for metrics, logs, traces, and profiles.

What can Alloy do?

• Programmable pipelines: Use a rich expression-based syntax for configuring powerful observability pipelines.

• OpenTelemetry Collector Distribution: Alloy is a distribution of OpenTelemetry Collector and supports dozens of its components, alongside new components that make use of Alloy's programmable pipelines.

• Big tent: Alloy embraces Grafana's "big tent" philosophy, where Alloy can be used with other vendors or open source databases. It has components to perfectly integrate with multiple telemetry ecosystems:

  • OpenTelemetry Collector
  • Prometheus
  • Grafana Loki
  • Grafana Pyroscope

• Kubernetes-native: Use components to interact with native and custom Kubernetes resources; no need to learn how to use a separate Kubernetes operator.

• Shareable pipelines: Use modules to share your pipelines with the world.

• Automatic workload distribution: Configure Alloy instances to form a cluster for automatic workload distribution.

• Centralized configuration support: Alloy supports retrieving its configuration from a server for centralized configuration management.

• Debugging utilities: Use the built-in UI for visualizing and debugging pipelines.

Example

otelcol.receiver.otlp "example" {
  grpc {
    endpoint = "127.0.0.1:4317"
  }

  output {
    metrics = [otelcol.processor.batch.example.input]
    logs    = [otelcol.processor.batch.example.input]
    traces  = [otelcol.processor.batch.example.input]
  }
}
