普罗米修斯:普罗米修斯没有发现的豆荚度量

Question

我目前正在我的pod中运行metrics server。数据正在发送到位于localhost:9090的pod中。我可以通过curl获取pod中的数据。deployment.yaml被注释为抓取数据，但我在pod中看不到任何新的指标。我做错了什么？

我在pod内部看到的指标：

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

    action: keep
    regex: true
  - source_labels: [__address__]
    action: replace
    regex: ([^:]+)(?::\d+)?
    replacement: $1:9090
    target_label: __address__
  - source_labels: [__meta_kubernetes_service_name]
    action: replace
    target_label: kubernetes_name

端口号是正确的。我做错了什么？

您的kubernetes_sd_configs配置为查找由服务创建的endpoints。您是否为您的服务创建了端点？您可以在您的名称空间中使用kubectl get endpoints进行检查。如果你不想创建一个服务，我想你也可以配置Prometheus来抓取pod目标，查看the docs获取更多信息。

documentation for metrics and labels还说指标名称必须与正则表达式[a-zA-Z_:][a-zA-Z0-9_:]*匹配，因此指标名称中的破折号(-)也可能是一个问题。
