   - Element: **Event Notifications** (link) — in the left navigation panel
   - Notes: Ensure you are in the correct region if managing multi-region resources.

2. Locate the target event notification in the list.
   - Element: table row containing your notification (table_row) — in the main content area
   - Notes: Use the search or filter options if you have many notifications.

3. Click the **Edit** button in the **Actions** column for the selected notification.
   - Element: **Edit** (button) — in the Actions column of the corresponding row
   - Notes: A configuration dialog or form will appear.

   - Element: Event type selection area (checkbox) — in the main content area of the form
   - Notes: For details on available event types, refer to the "Create an event notification" documentation. Only event types can be modified; the notification method (e.g., MNS or CloudMonitor) is fixed after creation.

   - Notes: After clicking, wait for the success confirmation message. The page may refresh automatically.

## FAQ

Q: Can I change the notification method (e.g., from MNS to CloudMonitor) when editing an event notification?
A: No. The notification method is set during creation and cannot be modified. You must delete the existing notification and create a new one with the desired method.

Q: Where do I find the list of available event types?
A: The available event types are displayed as checkboxes in the edit form. For detailed descriptions, consult the "Create an event notification" guide in the Auto Scaling documentation.

Q: What permissions are required to modify an event notification?
A: Your RAM user must have the `ess:ModifyNotificationConfiguration` permission or equivalent administrative access to Auto Scaling resources.

Q: Will changing event types affect already-triggered notifications?
A: No. Modifications only apply to future events. Past notifications are unaffected.

Q: Is there a limit to how many times I can edit an event notification?
A: There is no documented limit. You can modify the event types as often as needed, provided you have the necessary permissions.
