Awesome

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]
  }
}

otelcol.processor.batch "example" {
  output {
    metrics = [otelcol.exporter.otlp.default.input]
    logs    = [otelcol.exporter.otlp.default.input]
    traces  = [otelcol.exporter.otlp.default.input]
  }
}

otelcol.exporter.otlp "default" {
  client {
    endpoint = "my-otlp-grpc-server:4317"
  }
}

Release cadence

A new minor release is planned every six weeks.

The release cadence is best-effort: if necessary, releases may be performed outside of this cadence, or a scheduled release date can be moved forwards or backwards.

Minor releases published on cadence include updating dependencies for upstream OpenTelemetry Collector code if new versions are available. Minor releases published outside of the release cadence may not include these dependency updates.

Patch and security releases may be published at any time.
