我无法让酒店收集器工作，我是开放元素学的新手，所以感觉我在某个地方犯了一个愚蠢的错误
这是我的python样例脚本，它应该创建一个应该导出的样例跟踪，由openelement -collector拾取并推送到grafana tempo后端
from opentelemetry import trace

provider = TracerProvider()

span_processor = BatchSpanProcessor(span_exporter)
provider.add_span_processor(processor)
provider.add_span_processor(span_processor)
trace.set_tracer_provider(provider)
tracer = trace.get_tracer(__name__)
with tracer.start_as_current_span("foo"):
with tracer.start_as_current_span("bar"):

print("Hello world from OpenTelemetry Python!")
这是我运行它时的输出:

但是在grafana tempo中找不到这个trace:

所以我尝试了config.exporters.otlp.endpoint的不同值-没有效果。
任何想法?
我遇到过一个类似的问题，我在openetretry -collector中有痕迹，但无法在Grafana Tempo中导出它们。
我想你的问题是接收器的配置似乎无效(但这只是一个猜测)。
我认为应该是这样的:
config:
receivers:
otlp:
protocols:
grpc:
endpoint: 0.0.0.0:4317
http:
endpoint: 0.0.0.0:4318
一旦您在openelometry -collector中有了跟踪，您应该有这些类型的日志:
2022-10-21T14:38:22.641Z info TracesExporter {"kind": "exporter", "data_type": "traces", "name": "logging", "#spans": 5}
2022-10-21T14:38:32.658Z info TracesExporter {"kind": "exporter", "data_type": "traces", "name": "logging", "#spans": 30}
下面是我在Kubernetes上使用社区Helm图表的工作配置:
执掌图表:

- tempo-distributed: https://github.com/grafana/helm-charts/tree/main/charts/tempo-distributed
