->**Note:** For `DotNet` auto-instrumentation, by default, operator sets the `OTEL_DOTNET_AUTO_TRACES_ENABLED_INSTRUMENTATIONS` environment variable which specifies the list of traces source instrumentations you want to enable. The value that is set by default by the operator is all available instrumentations supported by the `openTelemery-dotnet-instrumentation` release consumed in the image, i.e. `AspNet,HttpClient,SqlClient`. This value can be overriden by configuring the environment variable explicitely.
