To enable telemetry for a Business Central SaaS tenant, you must first provision an Application Insights resource in the Azure portal. Microsoft best practices recommend using the customer's subscription for data sovereignty. Once created, you copy the Connection String (formerly the Instrumentation Key) and paste it into the specific environment settings within the Business Central Admin Center. This establishes the link. Finally, to verify that signals are being ingested, you navigate to the Logs section of the Application Insights resource and query the traces table, where Business Central telemetry data is stored.
