Overall Status
The Volume Health Monitor is implemented in two components: External Health Monitor Controller and Kubelet.
- The External Health Monitor Controller has been Alpha since Kubernetes 1.19.
- When this feature was first introduced in Kubernetes 1.19, there was an External Health Monitor Agent that monitors volume health from the node side. In the Kubernetes 1.21 release, the node side volume health monitoring logic was moved to Kubelet as an Alpha feature to avoid duplicate CSI RPC calls.
