Project Introduction

Summary

Grafana Alloy is a specialized distribution of the OpenTelemetry Collector that introduces programmable pipelines powered by the River configuration language. This allows users to build highly flexible and dynamic workflows for collecting, transforming, and exporting telemetry data.

Problem Solved

Standard OpenTelemetry Collector configurations can be rigid for complex scenarios requiring conditional logic, dynamic routing, or advanced data manipulation. Grafana Alloy addresses this by providing a programmable layer for highly customized telemetry processing.

Core Features

Programmable Pipelines (River)

Define complex data processing and routing logic using the expressive River configuration language.

OpenTelemetry Native

Fully compatible with OpenTelemetry data formats and protocols (OTLP).

Unified Telemetry Processing

Process and export all three telemetry signals: metrics, logs, and traces.

Extensible Architecture

Leverages a large ecosystem of OpenTelemetry receivers, processors, and exporters.

Tech Stack

Go
OpenTelemetry Collector
River Configuration Language
gRPC
Protobuf

Use Cases

Grafana Alloy's programmable nature makes it suitable for a variety of advanced telemetry processing scenarios:

Conditional Data Routing

Details

Route metrics, logs, or traces to different backend systems (e.g., production data to Prometheus/Loki/Tempo, staging data to a test sink) based on attributes or dynamic conditions.

User Value

Optimize storage costs and improve data organization by directing specific data streams to appropriate destinations.

Advanced Data Transformation & Filtering

Details

Implement custom data transformations, enrich traces with external service metadata, filter noisy logs based on complex patterns, or aggregate metrics before export.

User Value

Improve the signal-to-noise ratio of telemetry data and ensure data sent to backends is relevant and correctly formatted.

Implementing Custom Sampling Logic

Details

Apply intelligent sampling strategies to traces or logs based on attributes like error codes, latency, or user IDs, reducing volume while retaining important signals.

User Value

Manage high telemetry volume effectively, reducing ingest costs without losing critical observability insights.
