如何在otel-fargate-容器-inghts.yaml的过滤部分访问荚名/lable

Question

我遵循了https://aws.amazon.com/blogs/containers/introducing-amazon-cloudwatch-container-insights-for-amazon-eks-fargate-using-aws-distro-for-opentelemetry/中的指令，我只想向CloudWatch发送一些度量。我不知道如何访问豆荚的名称/标签，所以我使用了PodName。我搞错了。以下是过滤器部分：

 filter:
        metrics:
          include:
            match_type: expr
            expressions:
            - MetricName startsWith "pod_cpu" 
          exclude:
            match_type: expr
            expressions:
            - not (PodName startsWith "abcd")

部署之后，我检查了日志：

谢谢你提前帮忙，朱莉

请参阅https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/processor/filterprocessor#using-an-expr-match_type

Podname是标签，所以它应该是：

          exclude:
            match_type: expr
            expressions:
            - not (Label("PodName") startsWith "abcd")
