适用场景

接入 Grafana Cloud 发送遥特定

解决思路

  1. 在 Grafana Cloud portal → My Account → Stack → Details 获取各信号凭据：Metrics 用 Prometheus remote write URL、username、password/API key；Logs 用 Loki URL、username、password/API key；Traces 用 Tempo OTLP endpoint、username、password/API key；Profiles 用 Pyroscope URL、username、password/API key。
  2. 推荐用 Alloy 发送所有信号。metrics 配置：prometheus.scrape "app" { targets = [{"__address__" = "localhost:8080"}] forward_to = [prometheus.remote_write.cloud.receiver] }；prometheus.remote_write "cloud" { endpoint { url = "https://prometheus-prod-xx.grafana.net/api/prom/push" basic_auth { username = sys.env("PROM_USER") password = sys.env("GRAFANA_CLOUD_API_KEY") } } }。
  3. Alloy logs 配置：loki.source.file "app" { targets = [{__path__ = "/var/log/app/*.log", job = "app"}] forward_to = [loki.write.cloud.receiver] }；loki.write "cloud" { endpoint { url = "https://logs-prod-xx.grafana.net/loki/api/v1/push" basic_auth { username = sys.env("LOKI_USER") password = sys.env("GRAFANA_CLOUD_API_KEY") } } }。
  4. Alloy traces 配置：otelcol.receiver.otlp "default" { grpc { endpoint = "0.0.0.0:4317" } http { endpoint = "0.0.0.0:4318" } output { traces = [otelcol.exporter.otlp.cloud.input] } }；otelcol.exporter.otlp "cloud" { client { endpoint = "tempo-prod-xx.grafana.net:443" auth = otelcol.auth.basic.cloud.handler } }；otelcol.auth.basic "cloud" { username = sys.env("TEMPO_USER") password = sys.env("GRAFANA_CLOUD_API_KEY") }。
  5. 直接用 Prometheus remote write：在 prometheus.yml 中配置 remote_write: - url: https://prometheus-prod-xx.grafana.net/api/prom/push basic_auth: username: "123456" password: "your-api-key"；可选 write_relabel_configs: - source_labels: [__name__] regex: "go_.*" action: drop 以丢弃高基数指标。
  6. 直接用 Loki Push (curl)：curl -X POST https://logs-prod-xx.grafana.net/loki/api/v1/push -H "Content-Type: application/json" -u "123456:your-api-key" -d '{"streams":[{"stream":{"app":"myapp","env":"prod"},"values":[["1706745600000000000","application started"]]}]}'。
  7. OpenTelemetry SDK → Grafana Cloud：设置 export OTEL_EXPORTER_OTLP_ENDPOINT="https://otlp-gateway-prod-xx.grafana.net/otlp"；export OTEL_EXPORTER_OTLP_HEADERS="Authorization=Basic $(echo -n '123456:your-api-key' | base64)"；export OTEL_SERVICE_NAME="my-service"。Python 示例：from opentelemetry import trace; from opentelemetry.exporter.otlp.proto.http.trace_exporter import OTLPSpanExporter; from opentelemetry.sdk.trace import TracerProvider; from opentelemetry.sdk.trace.export import BatchSpanProcessor; provider = TracerProvider(); exporter = OTLPSpanExporter() # reads OTEL_EXPORTER_OTLP_* env vars; provider.add_span_processor(BatchSpanProcessor(exporter)); trace.set_tracer_provider(provider)。
  8. Cloud Integrations：从 Grafana Cloud UI 或 API 安装预构建集成。列出可用集成：curl https://integrations-api-prod.grafana.net/api/v1/integrations -H "Authorization: Bearer <api-key>"；安装 AWS CloudWatch：curl -X POST https://integrations-api-prod.grafana.net/api/v1/integrations/cloudwatch -H "Authorization: Bearer <api-key>" -H "Content-Type: application/json" -d '{"name": "aws-prod", "config": {...}}'。常见集成：AWS CloudWatch、Azure Monitor、GCP、Kubernetes、Docker、MySQL、PostgreSQL、Redis、Nginx、Apache、JVM、Node.js、Python、.NET。
  9. Kubernetes Agent Operator / Helm chart grafana/k8s-monitoring：在 values.yaml 设置 cluster.name: production；externalServices.prometheus.host: https://prometheus-prod-xx.grafana.net，basicAuth.username: "123456"，basicAuth.password.secretName: grafana-cloud-secret，basicAuth.password.secretKey: api-key；externalServices.loki.host: https://logs-prod-xx.grafana.net，basicAuth.username: "234567"，basicAuth.password.secretName: grafana-cloud-secret，basicAuth.password.secretKey: api-key；metrics.enabled: true，metrics.podMonitors.enabled: true，metrics.serviceMonitors.enabled: true；logs.pod_logs.enabled: true；traces.enabled: true。然后运行 helm install k8s-monitoring grafana/k8s-monitoring --version 4.1.4 -n monitoring --create-namespace -f values.yaml。
  10. API Key 管理：用 Grafana API 创建 API key：curl -X POST https://yourstack.grafana.net/api/auth/keys -H "Content-Type: application/json" -u "admin:adminpassword" -d '{"name": "alloy-writer", "role": "MetricsPublisher", "secondsToLive": 0}'。数据摄入角色：MetricsPublisher、LogsPublisher、TracesPublisher、ProfilesPublisher。
