opentelemetry-propagator-gcp 1.7.0

安装

pip install opentelemetry-propagator-gcp

用法

CloudTraceOneWayPropagator 读取Google Cloud X-Cloud-Trace-Context格式，但不将X-Cloud-Trace-Context头信息写入出站请求。它旨在与下面的CompositePropagator一起使用。

from opentelemetry.propagate import set_global_textmap
from opentelemetry.propagators.composite import CompositePropagator
from opentelemetry.propagators.cloud_trace_propagator import (
    CloudTraceOneWayPropagator,
)
set_global_textmap(
    CompositePropagator([
        CloudTraceOneWayPropagator(),
        propagate.get_global_textmap(),
    ]),
)

CloudTraceFormatPropagator 读取和写入X-Cloud-Trace-Context头信息格式。请注意，在 使用此传播器时，sampled位被解释为TRACE_TRUE标志，这可能导致比预期的更高的采样率。请参阅跟踪文档 <https://cloud.google.com/trace/docs/setup#force-trace>以获取更多上下文。

from opentelemetry.propagate import set_global_textmap
from opentelemetry.propagators.cloud_trace_propagator import (
    CloudTraceFormatPropagator,
)

# Set the X-Cloud-Trace-Context header
set_global_textmap(CloudTraceFormatPropagator())

from opentelemetry.propagate import set_global_textmap
from opentelemetry.propagators.cloud_trace_propagator import (
    CloudTraceFormatPropagator,
)

# Set the X-Cloud-Trace-Context header
set_global_textmap(CloudTraceFormatPropagator())
