Managed Service for Prometheus：將 AWS CloudWatch 指標接入可觀測監控 Prometheus 版

1.1 下載並修改配置values.yaml

點此擷取values.yaml

修改說明：

# 配置Prometheus Scrape 路徑和連接埠
podAnnotations: {
  prometheus.io/path: /metrics,
  prometheus.io/port: "5000",
  prometheus.io/scrape: "true"
}

# 配置 AWS 的認證方式，自行選擇1個，推薦 ak/sk 方式
aws:
  role:

  # The name of a pre-created secret in which AWS credentials are stored. When
  # set, aws_access_key_id is assumed to be in a field called access_key,
  # aws_secret_access_key is assumed to be in a field called secret_key, and the
  # session token, if it exists, is assumed to be in a field called
  # security_token
  secret:
    name:
    includesSessionToken: false

  # Note: Do not specify the aws_access_key_id and aws_secret_access_key if you specified role or secret.name before
  aws_access_key_id:
  aws_secret_access_key:

#採集 CloudWatch 的指標配置，請您按需配置，只需配置用到的產品和指標及統計運算元，AWS CloudWatch 會按請求的指標個數計費

1.2 安裝 Helm 應用

下載最新版本 Helm 應用

helm install -f values.yaml yace-exporter-cw ./prometheus-yet-another-cloudwatch-exporter-0.40.0.tgz -n aws-cloudwatch

或者線上拉鏡像安裝：

helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update
helm install -f values.yaml yane-exporter-cw prometheus-community/prometheus-yet-another-cloudwatch-exporter -n aws-cloudwatch
