DVO Updates
On managed clusters, the DVO updates automatically.
The Deployment Validation Operator (DVO) on on-premises OpenShift clusters
Administrators of on-premises clusters must install the Deployment Validation Operator (DVO) from OperatorHub in the OpenShift web console. On-premises cluster administrators can also configure the default set of KubeLinter checks.
The Red Hat Lightspeed advisor does not have recommendations for all of the checks that KubeLinter has available.

Add-on service management
From OpenShift Cluster Manager, you can manage the add-ons installed on your OpenShift cloud services clusters. Add-ons are services that you can install to enhance the capabilities of your Red Hat OpenShift Dedicated and Red Hat OpenShift Service on AWS (ROSA) clusters.
To access your add-ons and find information about them, navigate to your cluster’s Add-ons tab in OpenShift Cluster Manager, and select the add-on.
