Option / documentation to filter out sentry internal transactions from default Opentelemetry export

[ivan-klass]

Problem Statement

When using sentry-opentelemetry-agent while intentionaly keeping the main (otlp) exporter, in my traces panel I see a lot of internal sentry requests performed multiple times per second.
I would prefer a simple way to disable it, especially when it's not SENTRY_DEBUG.

I've tried sentry-opentelemetry-agentcustomization but it kind of lacks documentation:

• adding it as a runtime dependency doesn't seem to change the behavior
• adding it as yet another java agent doesn't work:

Error occurred during initialization of VM
agent library failed Agent_OnLoad: instrument
Failed to find Premain-Class manifest attribute in /opt/docker/bin/../sentry-opentelemetry-agentcustomization/sentry-opentelemetry-agentcustomization-8.0.0-alpha.1.jar

Solution Brainstorm

Add a boolean property and env var like sentry.internal.otel-export andSENTRY_INTERNAL_OTEL_EXPORT

Thanks for opening this issue @ivan-klass, we're currently in the process of reworking our OpenTelemetry Agent. I think it should be enough to simply use SamplingDecision.DROP in OpenTelemetry Sampler when we detect an internal Sentry span. Would you agree?

@adinauer thanks! Sounds good. Waiting for the next 8.x.x jar (8.0.0-alpha.2 ?) so I can verify

Hey @ivan-klass, we've just released 8.0.0-alpha.2 of the Java SDK, there's instructions how to upgrade in the changelog. If you decide to give it a try, any feedback is welcome 🙏 .
