Chapter 4. Customer Privacy
Various Microsoft products have a feature that reports usage statistics, analytics, and various other metrics to Microsoft over the network. They call this Telemetry. Red Hat is disabling telemetry because we do not recommend sending customer data to anyone without an explicit permission.
As part of the scl enable command, we automatically set an environment variable that tells the CLI to disable its telemetry reporting. Any customer that uses scl enable to run .NET Core will not report telemetry information to Microsoft. This helps keep customer information confidential. Customers are free to override the environment variable after using scl enable to report telemetry, if they wish.
Customers can enable telemetry by unsetting the environment variable DOTNET_CLI_TELEMETRY_OPTOUT. See .NET Core Tools Telemetry for more information.
