grafana tempo sigv4 支持普羅米修斯后端？

Question

grafana tempo backend sign (sigv4) 可以請求它發送到 aws prometheus (AMP) 嗎？

metrics_generator:
  registry:
    external_labels:
      source: tempo
      cluster: example
  storage:
    path: /tmp/tempo/generator/wal
    remote_write:
      - url: https://aps-workspaces.eu-central-1.amazonaws.com/workspaces/ws-2354ezthd34w4ter/api/v1/remote_write
        send_exemplars: true

或者是否有一個代理服務器可以在執行簽名工作的速度和普羅米修斯之間運行？

Answer 1

aws-sigv4-proxy為我解決了這個問題。

docker run --name sigv4proxy -ti --rm \
--network=host \
public.ecr.aws/aws-observability/aws-sigv4-proxy:1.6.1 \
-v --name aps --region eu-central-1 \
--host aps-workspaces.eu-central-1.amazonaws.com

現在tempo可以使用localhost訪問AMP（aws managed prometheus）

  storage:
    path: /tmp/tempo/generator/wal
    remote_write:
      - url: http://localhost:8080/workspaces/ws-1d8a668e-382b-4c49-9354-ad099f2b6260/api/v1/remote_write #http://prometheus:9090/api/v1/write
        send_exemplars: true
