用于运行Pod和节点的Kubernetes Prometheus指标? [英] Kubernetes prometheus metrics for running pods and nodes?

问题描述

我已经通过遵循普罗米修斯文档.

I've set up prometheus to monitor kubernetes metrics by following the prometheus documentation.

许多有用的指标现在显示在Prometheus中.

A lot of useful metrics now show up in prometheus.

但是，我看不到任何引用我的Pod或节点状态的指标.

However, I can't see any metrics referencing the status of my pods or nodes.

理想情况-我希望能够绘制pod状态(运行，待处理，CrashLoopBackOff，错误)和节点(NodeReady，就绪)的图形.

Ideally - I'd like to be able to graph the pod status (Running, Pending, CrashLoopBackOff, Error) and nodes (NodeReady, Ready).

此指标在任何地方吗?如果没有，我可以在某个地方添加它吗?以及如何?

Is this metric anywhere? If not, can I add it somewhere? And how?

推荐答案

常规kubernetes设置不会公开这些指标-进一步的讨论

The regular kubernetes setup does not expose these metrics - further discussion here.

但是，可以使用另一项服务来收集这些集群级别的度量: https://github. com/kubernetes/kube-state-metrics .

However, another service can be used to collect these cluster level metrics: https://github.com/kubernetes/kube-state-metrics.

目前，这提供了听起来像我想要的那样的node_status_ready和pod_container_restarts.

This currently provides node_status_ready and pod_container_restarts which sound like what I want.
