An open-source OpenTelemetry Collector distribution with programmable pipelines and built-in Prometheus support
Grafana Alloy Project Detailed Introduction
Project Overview
Grafana Alloy is an open-source OpenTelemetry collector distribution with built-in Prometheus pipelines, supporting metrics, logs, traces, and profiles. It is a next-generation observability data collection tool launched by Grafana Labs, designed to replace Grafana Agent and provide more powerful features.
- GitHub Address: https://github.com/grafana/alloy
Core Features
1. Flexible Programmable Pipelines
Use a rich expression-based syntax to configure powerful observability pipelines. Alloy provides an intuitive configuration method, allowing users to easily build complex data processing workflows.
2. Multi-Ecosystem Support
- OpenTelemetry Compatibility: Fully compatible with the most popular open-source observability standards, such as OpenTelemetry and Prometheus.
3. Rich Component Ecosystem
Alloy uses over 120 components to collect telemetry data from applications, databases, and OpenTelemetry collectors. These components cover various data sources and target systems, providing users with great flexibility.
4. Multiple Telemetry Signal Support
- Metrics
- Logs
- Traces
- Profiles
Technical Architecture
Data Collection
Telemetry data can be pushed to Alloy, or Alloy can pull data from data sources. This two-way data collection method provides flexibility for different use cases.
Data Processing and Transformation
Alloy processes data and transforms it for sending. Transformations can be used to inject additional metadata into telemetry or filter out unwanted data.
Data Output
Alloy sends data to OpenTelemetry-compatible databases or collectors, the Grafana stack, or Grafana Cloud.
Kubernetes Native Support
Use components to interact with native and custom Kubernetes resources; no need to learn how to use a separate Kubernetes operator. This makes Alloy easier to deploy and manage in containerized environments.
Shareable Pipelines
Use modules to share pipelines. This modular design makes it easy for teams to share and reuse configurations, improving efficiency and consistency.
Relationship with Grafana Agent
Existing Grafana Agent Flow users will feel very familiar when using Alloy because Alloy uses the same components, code, and concepts first introduced in Grafana Agent Flow. Alloy is actually an evolution of Grafana Agent, providing more enhancements.
