Question

我目前在我的广告连播中运行指标服务器。数据在localhost：9090的pod中发送。我能够通过curl获取pod内部的数据。注释deploy.yaml可以抓取数据，但在pod中看不到任何新指标。我在做什么错了？

我在广告连播中看到的指标：

cpu_usage{process="COMMAND", pid="PID"} %CPU
cpu_usage{process="/bin/sh", pid="1"} 0.0
cpu_usage{process="sh", pid="8"} 0.0
cpu_usage{process="/usr/share/filebeat/bin/filebeat-god", pid="49"} 0.0
cpu_usage{process="/usr/share/filebeat/bin/filebeat", pid="52"} 0.0
cpu_usage{process="php-fpm:", pid="66"} 0.0
cpu_usage{process="php-fpm:", pid="67"} 0.0
cpu_usage{process="php-fpm:", pid="68"} 0.0
cpu_usage{process="nginx:", pid="69"} 0.0
cpu_usage{process="nginx:", pid="70"} 0.0
cpu_usage{process="nginx:", pid="71"} 0.0
cpu_usage{process="/bin/sh", pid="541"} 0.0
cpu_usage{process="bash", pid="556"} 0.0
cpu_usage{process="/bin/sh", pid="1992"} 0.0
cpu_usage{process="ps", pid="1993"} 0.0
cpu_usage{process="/bin/sh", pid="1994"} 0.0

deployment.yaml

    replacement: $1:9090
    target_label: __address__
  - source_labels: [__meta_kubernetes_service_name]
    action: replace
    target_label: kubernetes_name

端口号正确。我在做什么错了？

您的kubernetes_sd_configs配置为查找由服务创建的endpoints。您是否为服务创建了端点？您可以在名称空间中使用kubectl get endpoints进行检查。如果您不想创建服务，我想您也可以配置Prometheus来抓取Pod目标，请查看the docs以获取更多信息。

此外，documentation for metrics and labels说度量标准名称必须与正则表达式[a-zA-Z_:][a-zA-Z0-9_:]*匹配，因此度量标准名称中的破折号（-）也可能是一个问题。
