Description
There is no mechanism today to suppress telemetry arising from SDK's own operations. For example, OTLP Exporter uses tonic, which is instrumented with tracing crate. When one enables tracing-appender, along with OTLP Exporter, all the logs emitted by tonic inside OTLPExporter, gets routed to OpenTelemetry! This is a never ending "live loop", as every export cause logs to be produced, which causes export to occur again, which further creates logs again and so on.
There was never a spec written for this (open-telemetry/opentelemetry-specification#530), but languages like Python, .NET had provided solutions for this.
Opening an issue to track adding a capability to "Suppress instrumentation" in OTel Rust SDK, and have the official exporters leverage it.
