+Kubernetes core components can expose a suite of _z-endpoints_ to make it easier for users
+to debug their cluster and its components. These endpoints are strictly to be used for human
+inspection to gain real time debugging information of a component binary.
+Avoid automated scraping of data returned by these endpoints; in Kubernetes {{< skew currentVersion >}}
+these are an **alpha** feature and the response format may change in future releases.

+Kubernetes v{{< skew currentVersion >}} allows you to enable _z-pages_ to help you troubleshoot
+problems with its core control plane components. These special debugging endpoints provide internal

+### statusz
+
+Enabled using the `ComponentStatusz` [feature gate](/docs/reference/command-line-tools-reference/feature-gates/),
+the `/statusz` endpoint displays high level information about the component such as its Kubernetes version, emulation version, start time and more.
+
+The `/statusz` response from the API server is similar to:

+
+来自 API 服务器的 `/statusz` 响应类似于：
