红帽全球峰会第 5 章 OpenShift Container Platform 中的 Cluster Network Operator
OpenShift Container Platform 的 Network Observability Operator 部署一个监控管道。此管道收集并增强由 eBPF 代理 生成的网络流量流。
5.1. 查看状态
使用 oc get 命令检查 FlowCollector 资源状态以及 eBPF 代理,flowlogs-pipeline, 和 console 插件 Pod 的状态，查看 Network Observability Operator 的运行状态。
Network Observability Operator 提供 Flow Collector API。创建 Flow Collector 资源时，它会部署 pod 和服务，以在 Loki 日志存储中创建和存储网络流，并在 OpenShift Container Platform Web 控制台中显示仪表板、指标和流。
流程
运行以下命令来查看
Flowcollector的状态：$ oc get flowcollector/cluster输出示例
