3.6.4. 使用 Prometheus 和 Grafana 监控 OpenShift Dev Spaces
您可以使用在集群中运行 Prometheus 和 Grafana 实例来收集和查看 OpenShift Dev Spaces 指标。
3.6.4.1. 安装 Prometheus 和 Grafana
您可以通过应用 template.yaml 来安装 Prometheus 和 Grafana。本例中的 template.yaml 文件提供了一个基本配置、Deployment 和 Services 的监控堆栈。
另外，您可以使用 Prometheus Operator 和 Grafana Operator。
先决条件
- oc
流程
使用 template.yaml 安装 Prometheus 和 Grafana：
为 Prometheus 和 Grafana 创建一个新项目，
监控：$ oc new-project monitoring
在
monitoring项目中应用template.yaml：$ oc apply -f template.yaml -n monitoring
