Use storage-operator to monitor the storage resources of an ACK cluster - Container Service for Kubernetes

You can deploy storage-operator in a Container Service for Kubernetes (ACK) cluster. After storage-operator is deployed, you can view the status of persistent volumes (PVs) and persistent volume claims (PVCs), the trend of PV and PVC status, and the PVs and PVCs that are in the abnormal state. This topic describes how to monitor the storage resources of an ACK cluster by using storage-operator.

Prerequisites

An ACK cluster is created. For more information, see Create an ACK managed cluster.

Billing rules for storage-operator

After you enable the monitoring feature, the storage-operator component will automatically send metrics to Managed Service for Prometheus. These metrics are considered custom metrics. Fees may be charged for custom metrics.

To avoid incurring additional fees, we recommend that you read and understand Billing overview before you enable this feature. The fees may vary based on the cluster size and number of applications. You can follow the steps in View resource usage to monitor and manage resource usage.
