第 1 章健康指标

您可以使用指标来监控组件的健康状况。

请参阅以下文档：

使用 metrics 服务

1.1. 使用 metrics 服务
复制链接

您可以使用 metrics (指标) 来监控 Red Hat Advanced Cluster Management for Kubernetes 中的组件健康状况。在 Metrics chronicle 概述中记录了许多自定义指标。

1.1.1. 访问 hub 集群指标服务
复制链接

要查看收集的指标，您必须在 hub 集群上公开 metrics 服务。如果您的指标已在 Grafana 仪表板中公开，这个过程是可选的。

在 OpenShift Container Platform 控制台中查找 metrics 服务。点 Observe > Metrics。

如果您没有在 Grafana 仪表板、Grafana Explorer 或 OpenShift Container Platform 控制台中看到指标，则 Prometheus 可能无法配置为提取指标。继续使用 Scrapping with Prometheus 来公开您的指标。

1.1.2. Scraping with Prometheus

您可以使用 Prometheus 来公开从产品控制台公开的指标。请参阅 hub 和受管集群指标的步骤。

1.1.2.1. 提取 hub 集群
复制链接

请参阅以下流程来公开 hub 集群的指标。这些文件位于 openshift-monitoring 命名空间中：

创建用于收集服务和公开指标的 ServiceMonitor。请参阅以下 YAML 示例：

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: hub-subscription-metrics
  namespace: openshift-monitoring
spec:
  endpoints:
  - port: metrics
  namespaceSelector:
    matchNames:
    - open-cluster-management
  selector:
    matchLabels:
      app: hub-subscription-metrics

apiVersion: monitoring.coreos.com/v1
kind: ServiceMonitor
metadata:
  name: hub-subscription-metrics
