Amazon CloudWatch 代理 - Amazon CloudWatch
支持的 OpenTelemetry 组件配置示例

Amazon CloudWatch 代理

CloudWatch 代理基于 OpenTelemetry Collector 构建，因此您可以使用它来接收 OpenTelemetry 数据并将其发送到 CloudWatch OTLP 端点。对于大多数客户而言，这是向 CloudWatch 发送遥测数据的推荐方式，因为单个代理还可以支持 CloudWatch Application Signals 和 CloudWatch Enhanced Container Insights 等精选体验。

目前，要通过代理发送 OpenTelemetry 数据，需要以 YAML 格式提供 OpenTelemetry 收集器配置，并将其附加到代理自身的配置中。使用 CloudWatch 代理配置文件启动代理，然后附加 OpenTelemetry YAML 文件：

/opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a fetch-config -c file:/tmp/agent.json -s
/opt/aws/amazon-cloudwatch-agent/bin/amazon-cloudwatch-agent-ctl -a append-config -c file:/tmp/otel.yaml -s

代理会在启动时合并这两个配置，并记录已解析的配置。为避免与代理自动创建的管道发生合并冲突，请在 OpenTelemetry YAML 中为每个组件和管道名称添加自定义后缀（例如 otlphttp/cwagent）。

支持的 OpenTelemetry 组件

以下 OpenTelemetry 组件可供您在附加的 YAML 配置中进行配置。请使用此处显示的组件类型名称作为 YAML 中的键。

组件类型 可用组件

接收器

otlp, prometheus, statsd, collectd, jmx, hostmetrics, filelog, tcplog, udplog, jaeger, zipkin, kafka, kubeletstats

处理器

batch, memory_limiter, filter, attributes, resource, resourcedetection, metricstransform, transform, cumulativetodelta, deltatocumulative, deltatorate, groupbyattrs, groupbytrace, k8sattributes, metricsgeneration, metricstarttime, probabilistic_sampler, span, tail_sampling

导出器

otlphttp, awsemf, awscloudwatchlogs, awsxray, prometheusremotewrite, debug

扩展程序

CloudWatch 代理仅支持向 AWS 目的地写入遥测数据。

配置示例

以下示例使用 otlphttp 导出器和 sigv4auth 扩展，将每个信号发送到相应的 CloudWatch OTLP 端点。每个组件和管道名称都使用 /cwagent 后缀，以避免与代理自动创建的管道发生冲突。将 region 替换为 AWS 区域。
