第 5 章 将追踪、日志和指标发送到 OpenTelemetry Collector

流程

1. 为 OpenTelemetry Collector 实例创建项目。

   apiVersion: project.openshift.io/v1
   kind: Project
   metadata:
     name: observability

   Copy to Clipboard Toggle word wrap

2. 创建一个服务帐户。

   apiVersion: v1
   kind: ServiceAccount
   metadata:
     name: otel-collector-sidecar
     namespace: observability

   Copy to Clipboard Toggle word wrap

3. 为 k8sattributes 和 resourcedetection 处理器的服务帐户授予权限。

   apiVersion: rbac.authorization.k8s.io/v1
   kind: ClusterRole
   metadata:
     name: otel-collector
   rules:
   - apiGroups: ["", "config.openshift.io"]
     resources: ["pods", "namespaces", "infrastructures", "infrastructures/status"]
     verbs: ["get", "watch", "list"]
   ---
   apiVersion: rbac.authorization.k8s.io/v1
   kind: ClusterRoleBinding
   metadata:
     name: otel-collector
   subjects:
   - kind: ServiceAccount
     name: otel-collector-sidecar
     namespace: observability
   roleRef:
     kind: ClusterRole
     name: otel-collector
     apiGroup: rbac.authorization.k8s.io

   Copy to Clipboard Toggle word wrap

4. 将 OpenTelemetry Collector 部署为 sidecar。

   apiVersion: opentelemetry.io/v1beta1
   kind: OpenTelemetryCollector
   metadata:
     name: otel
     namespace: observability
   spec:
     serviceAccount: otel-collector-sidecar
     mode: sidecar
     config:
       serviceAccount: otel-collector-sidecar
       receivers:
         otlp:
           protocols:
             grpc: {}
             http: {}
       processors:
         batch: {}
         memory_limiter:
           check_interval: 1s
           limit_percentage: 50
           spike_limit_percentage: 30
         resourcedetection:
           detectors: [openshift]
           timeout: 2s
       exporters:
         otlp:
           endpoint: "tempo-<example>-gateway:8090"

           tls:
             insecure: true
       service:
         pipelines:
           traces:
             receivers: [otlp]
             processors: [memory_limiter, resourcedetection, batch]
             exporters: [otlp]

   这指向使用 Tempo Operator 部署的 <example> TempoStack 实例的网关。

5. 使用 otel-collector-sidecar 服务帐户创建部署。
6. 在您的 Deployment 对象中添加 sidecar.opentelemetry.io/inject: "true" 注解。这将注入所有需要的环境变量，将工作负载中的数据发送到 OpenTelemetry Collector 实例。
