opentelemetry-processor-baggage 0.48b0

安装

pip install opentelemetry-processor-baggage

Add this span processor to a tracer provider.

Keys and values added to Baggage will appear on subsequent child spans for a trace within this service and be propagated to external services in accordance with any configured propagation formats configured. If the external services also have a Baggage span processor, the keys and values will appear in those child spans as well.

[!WARNING]

Do not put sensitive information in Baggage.

To repeat: a consequence of adding data to Baggage is that the keys and values will appear in all outgoing HTTP headers from the application.

## 使用

Add the span processor when configuring the tracer provider.

配置span处理器以在配置期间复制所有行李条目

from opentelemetry.processor.baggage import BaggageSpanProcessor, ALLOW_ALL_BAGGAGE_KEYS

tracer_provider = TracerProvider()
tracer_provider.add_span_processor(BaggageSpanProcessor(ALLOW_ALL_BAGGAGE_KEYS))

或者，您可以提供自定义的行李键谓词来选择要复制的行李键。

例如，仅复制以my-key开头的行李条目

starts_with_predicate = lambda baggage_key: baggage_key.startswith("my-key")
tracer_provider.add_span_processor(BaggageSpanProcessor(starts_with_predicate))

例如，仅复制匹配正则表达式^key.+的行李条目

regex_predicate = lambda baggage_key: baggage_key.startswith("^key.+")
tracer_provider.add_span_processor(BaggageSpanProcessor(regex_predicate))
