Grafana 出品的 OpenTelemetry Collector 发行版，用可编程管道统一采集指标、日志、链路和性能剖析数据

基于 OpenTelemetry Collector 的可编程遥测数据管道，用声明式配置把指标、日志和链路统一采集、处理并转发到 Grafana、Prometheus、Loki 等后端。

核心能力

  • 用基于表达式的配置语法编写可编程可观测性管道
  • 兼容 OpenTelemetry Collector 的数十个组件
  • 对接 Prometheus、Loki、Pyroscope 等多种遥测生态
  • 原生支持 Kubernetes 资源，无需额外 Operator
  • 通过模块共享管道，并可组建集群自动分配负载

容易踩的坑

README 未给出安装命令，需按官方文档选择对应平台的安装方式；配置使用 Alloy 自有表达式语法，与原生 OTel Collector YAML 不通用

内容由模型根据 README 生成，可能不完整或不准确，以官方文档为准。看原文 README

    1.21.0 (2026-10-16)

    ⚠ BREAKING CHANGES

    • otelcol.receiver.kafka: otelcol.receiver.kafka and otelcol.exporter.kafka metadata > retry > max_retries now defaults to 20 (was 3) and is now actually applied. Upstream's Kafka client silently ignored it since the franz-go migration. otelcol.exporter.kafka now also applies backoff. (#7366)
    • otelcol.connector.signaltometrics: otelcol.connector.signaltometrics error_mode now defaults to ignore (was propagate). A failing OTTL expression now skips the record and logs the error instead of dropping the whole payload. Set error_mode = "propagate" to restore the previous behavior. (#7366)
    • loki.write: loki.write configurations that set wal { enabled = true } now fail to load unless Alloy runs with --stability.level=experimental. To keep using the WAL, add --stability.level=experimental to the alloy run command. To keep the default stability level, remove the wal block or set enabled = false. (#7257)
    • loki.write: Remove tenant label from metrics (#7232)

    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:

    • 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 three weeks. Patch releases are published every one to two 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.
