Question

我在Kubernetes集群上运行Prometheus pod。我在Openstack中的实例上安装了node-exporter。它运行正常。我在prometheus配置文件中添加了它的配置。重新加载后，目标节点导出器显示但其状态为Down，错误为context deadline exceeded。我尝试增加scrape-timeout，但它也有用。休息所有目标都工作正常，UP。我试图从容器内部ping目标端点，它也没关系。但遗憾的是，内部容器中没有curl或wget来检查指标端点。这是配置文件片段。

- job_name: "node-exporter"
  metrics_path: '/metrics/'
  static_configs:
    - targets: ['192.168.248.243:9100']

我检查了prometheus日志，他们在这里。

我的Kubernetes版本是1.6.4。

从Kubernetes上运行的Prometheus中抓取节点导出器时出错
