我在kubeadm制作的多节点kubernetes集群上部署了prometheus 2.0。在访问prometheus仪表板时，即使在prometheus配置yaml文件中配置它后，我也无法查看pod和服务作业。普罗米修斯目标如下：。 这个问题与普罗米修斯版本有什么关系。我想我错了配置的语法部分。Kubernetes吊舱和服务没有在普罗米修斯目标中显示

回答：

我假设你正在做你的评论贴查询：

container_memory_usage_bytes{job="kubernetes-pods"}

这是不行的，因为你被过滤工作名称kubernetes-pods，但container_memory_usage_bytes来自cAdvisor。因此根据您的配置，作业名为kubernetes-cadvisor。

所以这应该工作：

container_memory_usage_bytes{job="kubernetes-cadvisor"}

由于该系列的名称是相当独特的，你可以省略作业名称：

container_memory_usage_bytes
