Guidance on Setting Global Tracer Provider in Phoenix OTEL

Zhuyi X. · 2025-04-30T00:30:17.644Z

is there any guidance on whether set_global_tracer_provider should be set to True or False when calling phoenix.otel.register, what's the pros and cons?

It seems likely that setting set_global_tracer_provider to True makes the TracerProvider the global default, which is useful for applications that rely on a single, consistent tracing configuration across the entire application. This can simplify the setup and ensure that all parts of the application use the same tracing configuration. However, setting it to False allows for more flexibility, enabling different parts of the application to use different tracing configurations, which might be beneficial in complex applications with varied tracing needs.Would you like more detail on this?
