Dear Customer,

To streamline your initial setup, starting at 10:00 (UTC+8) on March 6, 2026, Application Real-Time Monitoring Service (ARMS), including the Application Monitoring, Real User Monitoring (RUM), and Managed Service for OpenTelemetry sub-services, will activate automatically the first time you create an application.

You will not be charged for this activation. Billing starts only if you ingest custom metrics, allowing you to try the service at no cost.

Thank you for your continued support and trust in Alibaba Cloud.
