Volume health monitoring feature is implemented in two components: an External Health Monitor controller, and the {{< glossary_tooltip term_id="kubelet" text="kubelet" >}}. If a CSI Driver supports Volume Health Monitoring feature from the controller side, an event will be reported on the related {{< glossary_tooltip text="PersistentVolumeClaim" term_id="persistent-volume-claim" >}} (PVC) when an abnormal volume condition is detected on a CSI volume. --> Kubernetes _卷健康监测_ 是 Kubernetes 容器存储接口（CSI）实现的一部分。 卷健康监测特性由两个组件实现：外部健康监测控制器和 {{< glossary_tooltip term_id="kubelet" text="kubelet" >}}。 如果 CSI 驱动器通过控制器的方式支持卷健康监测特性，那么只要在 CSI 卷上监测到异常卷状态，就会在 {{< glossary_tooltip text="PersistentVolumeClaim" term_id="persistent-volume-claim" >}} (PVC) 中上报一个事件。 <!-- The External Health Monitor {{< glossary_tooltip text="controller" term_id="controller" >}} also watches for node failure events. You can enable node failure monitoring by setting the `enable-node-watcher` flag to true. When the external health monitor detects a node failure event, the controller reports an Event will be reported on the PVC to indicate that pods using this PVC are on a failed node. If a CSI Driver supports Volume Health Monitoring feature from the node side, an Event will be reported on every Pod using the PVC when an abnormal volume condition is detected on a CSI volume. --> 外部健康监测  {{< glossary_tooltip text="控制器" term_id="controller" >}} 也会监测节点失效事件。 如果要启动节点失效监测功能，你可以设置标志 `enable-node-watcher` 为 `true`。 当外部健康监测器检测到一个节点失效事件，控制器会报送一个事件，该事件会在 PVC 上继续上报， 以表明使用此 PVC 的 Pod 正位于一个失效的节点上。 如果 CSI 驱动程序支持节点测的卷健康检测，那当在 CSI 卷上检测到异常卷时，会在使用该 PVC 的每个Pod 上触发一个事件。 <!-- You need to enable the `CSIVolumeHealth` [feature gate](/docs/reference/command-line-tools-reference/feature-gates/) to use this feature from the node side. --> {{< note >}} 你需要启用 `CSIVolumeHealth` [特性门控](/zh/docs/reference/command-line-tools-reference/feature-gates/) ，才能从节点测使用此特性。 {{< /note >}} ## {{% heading "whatsnext" %}} <!-- See the [CSI driver documentation](https://kubernetes-csi.github.io/docs/drivers.html) to find out which CSI drivers have implemented this feature. --> 参阅 [CSI 驱动程序文档](https://kubernetes-csi.github.io/docs/drivers.html)， 可以找出有那些 CSI 驱动程序已实现了此特性。 </ins>  No newline at end of file
