Note on Persistent Grafana Dashboards: For users who are using Monitoring V2 v9.4.203 or below, uninstalling the Monitoring chart will delete the cattle-dashboards namespace, which will delete all persisted dashboards, unless the namespace is marked with the annotation helm.sh/resource-policy: "keep". This annotation is added by default in Monitoring V2 v14.5.100+ but can be manually applied on the cattle-dashboards namespace before an uninstall if an older version of the Monitoring chart is currently installed onto your cluster.
