+
+Vertical scaling involves increasing or decreasing resources to an existing database cluster.
+Resources that can be scaled include:, CPU cores/processing power and Memory (RAM).

 ### [Expand volume](volumeexpand.yaml)
 
 Volume expansion is the ability to increase the size of a Persistent Volume Claim (PVC) after it's created. It is introduced in Kubernetes v1.11 and goes GA in Kubernetes v1.24. It allows Kubernetes users to simply edit their PersistentVolumeClaim objects  without requiring any downtime at all if possible.

+### Observability
+
+There are various ways to monitor the cluster. Here we use Prometheus and Grafana to demonstrate how to monitor the cluster.
+
+#### Installing the Prometheus Operator
+
+You may skip this step if you have already installed the Prometheus Operator.
+Or you can follow the steps in [How to install the Prometheus Operator](../docs/install-prometheus.md) to install the Prometheus Operator.
+
+#### Create PodMonitor
+
+Apply the `PodMonitor` file to monitor the cluster:
+
+```bash
+kubectl apply -f examples/polardbx/pod-monitor.yaml
+```
+
+##### Access the Grafana Dashboard
+
+Login to the Grafana dashboard and import the dashboard [PolarDB-X Dashboard Overview](https://github.com/apecloud/kubeblocks-addons/blob/main/addons/polardbx/dashboards/polardbx-overview.json) to monitor the cluster.
+
 ### Delete
 
 If you want to delete the cluster and all its resource, you can modify the termination policy and then delete the cluster
 
 ```bash
-kubectl patch cluster polardbx-cluster -p '{"spec":{"terminationPolicy":"WipeOut"}}' --type="merge"
+kubectl patch cluster pxc -p '{"spec":{"terminationPolicy":"WipeOut"}}' --type="merge"
 
-kubectl delete cluster polardbx-cluster
