Does opentelemetry-dotnet-instrumentation support .AddSource("*")

[bangonkali]

Is it possible to do, .AddSource("*")?

I'm thinking of doing like below:

            services.AddOpenTelemetry()
                .ConfigureResource(resource => { resource.AddService("MYAPP"); })
                .WithTracing(tracing => tracing
                    .SetSampler(new AlwaysOnSampler())
                    .AddSource("*") // <--- Relevant Snippet
                    .AddRedisInstrumentation()
                    .AddAspNetCoreInstrumentation()
                    .AddHttpClientInstrumentation()
                    .AddEntityFrameworkCoreInstrumentation()
                    .AddSqlClientInstrumentation()
                    .AddOtlpExporter(c => c.Endpoint = configuration.Otel.Uri))
                .WithMetrics(metrics => metrics
                    .AddMeter("*") // <--- Relevant Snippet
                    .AddRuntimeInstrumentation()
                    .AddHttpClientInstrumentation()
                    .AddAspNetCoreInstrumentation()
                    .AddSqlClientInstrumentation()
                    .AddOtlpExporter(c => c.Endpoint = configuration.Otel.Uri));

Is this supported?

Hi @bangonkali, the auto-instrumentation package provides the following environment variables that would implement the same functionality as if you were configuring the SDK this way, which handles the "*" input:

• OTEL_DOTNET_AUTO_TRACES_ADDITIONAL_SOURCES (

  opentelemetry-dotnet-instrumentation/docs/config.md

  Line 417 in 802963f

  | `OTEL_DOTNET_AUTO_TRACES_ADDITIONAL_SOURCES` | Comma-separated list of additional `System.Diagnostics.ActivitySource` names to be added to the tracer at the startup. Use it to capture manually instrumented spans. | | [Experimental](https://github.com/open-telemetry/opentelemetry-specification/blob/main/specification/versioning-and-stability.md) |

  )
• OTEL_DOTNET_AUTO_METRICS_ADDITIONAL_SOURCES (
