### Managing deployed charts
Once deployed, you can:
-- View the chart status in the Add-ons tab
+- View the chart status and deployment history in the Add-ons tab
- Update values and redeploy
- Upgrade to newer chart versions
+- Compare changes between revisions
- Delete the chart when no longer needed
+### Viewing deployment history
+
+Each custom Helm chart add-on includes a **Deployments** tab that displays a full history of every revision deployed. For each deployment, you can see:
+
+- **Revision number** — the sequential deployment version
+- **Date** — when the deployment occurred
+- **Repository URL** — the Helm repository the chart was pulled from
+- **Chart name** and **version** — exactly which chart was installed
+
+To compare what changed between two deployments, click the **Changes** icon on any row. This opens a diff view showing the differences in chart name, repository URL, version, and values between that revision and the previous one.
+
+
+The add-on header also displays the chart name and version as metadata tags, so you can quickly identify which chart and version is currently deployed without opening the Deployments tab.

For more complex scenarios, you can deploy a **Grafana** addon, which is already configured with the existing observability
stack deployed in the cluster. Grafana makes it possible to explore, query and build dashboard to monitor any charts or
