The affected metrics are:

• VSwitchIpv4Usage
• VSwitchIpv6Usage
• VpcIpv4Usage
• VpcIpv6Usage

Update: The ipamScopeId dimension will be added to these metrics.

Impact: Significant data fluctuations may occur during the update and may trigger alert notifications. The data will return to normal after the update is completed.
