Upgrade the monitoring service

If you’ve installed the monitoring service using Helm, you can use Helm to upgrade it as well.

Prerequisites

The monitoring service must already be installed.

Follow the steps in this section to upgrade the monitoring service component using Helm.

Update your Helm repos:
```
helm repo update
```
Retrieve all custom values you used during install. Enter the following helm get values command to generate a YAML file, adjusting the value of the <namespace> parameter to match your environment:
```
helm get values --namespace <namespace> px-monitor -o yaml > values.yaml
```
Delete the post-install hook job. Enter the following kubectl delete job command, adjusting the value of the <namespace> parameter to match your environment:
```
kubectl -n <namespace> delete job pxcentral-monitor-post-install-setup
```
Remove the pxcentral-prometheus-operator deployment. Enter the following kubectl delete deployment command, adjusting the value of the <namespace> parameter to match your environment:
```
kubectl -n <namespace> delete deployment pxcentral-prometheus-operator
```
Upgrade the monitoring service component. Run the following helm upgrade command, using the -f flag to pass the custom values.yaml file you generated above and adjusting the value of the <namespace> parameter to match your environment:
```
helm upgrade px-monitor portworx/px-monitor --namespace <namespace>  -f values.yaml
```
