What’s happening?
The on-premises Commerce Scale Unit (CSU) installation fails due to the requirement to connect to specific Azure websites, which are blocked by the customer's policy.
 
Reason:
The CSU, whether cloud or on-premises, relies on certain external services for monitoring and telemetry purposes. The URLs in question are part of the Azure Monitor and Application Insights services, which are essential for tracking the performance, health, and usage of the CSU.
 
Resolution:
The following URLs are required for the CSU installation and their purposes are as follows: - https://dc.services.visualstudio.com/v2/track: Used by Application Insights to send telemetry data, such as performance metrics and diagnostic information, to Azure Monitor. - https://profiler.monitor.azure.com/: Used by the Azure Profiler to identify performance bottlenecks and optimize the performance of the CSU. - https://snapshot.monitor.azure.com/: Used by the Azure Snapshot Debugger to capture snapshots of the application state during exceptions to help diagnose issues.
It is not recommended to disable these services as they provide essential monitoring and diagnostic capabilities. Disabling them could lead to difficulties in identifying and resolving issues and may impact the overall health and performance of the system.
