.Net application: How to add custom Span/Trace usi...

Getting Data In

I have an ASP .Net application that is currently setup to be monitored using Splunk Open Telemetry (Signal Fx) using the automated tracer installed in the VM host.

I found a need to add custom trace or span for some of critical code path to gather more instrumentation. What is the best way to integrate into .Net app while still using the automated tracer installed in the VM Host?

These are the options I'm seeing:

Splunk Observability via SignalFx auto instrumentation
OpenTelemetry.io Nuget (manual or automatic instrumentation)
System.Diagnostics.DiagnosticSource to manually instrument and then collect these using OpenTelemetry.io Nuget

Which one would be the one that will not interfere with the automated tracer from Splunk?
