我正在尝试使用OTLPopentelemetry并向open telemetry-otlpHoneycomb 提供可观测数据。

我使用这样的东西作为概念证明（如果您想运行它，则将其提取到此存储库中： https: //github.com/timfpark/honeycomb-rust-poc）

fn init_tracer(metadata: &MetadataMap) -> Result<sdktrace::Tracer, TraceError> {
    let opentelemetry_endpoint =
        env::var("OTEL_ENDPOINT").unwrap_or_else(|_| "https://api.honeycomb.io".to_owned());
    let opentelemetry_endpoint =
        Url::parse(&opentelemetry_endpoint).expect("OTEL_ENDPOINT is not a valid url");

    opentelemetry_otlp::new_pipeline()
        .tracing()
        .with_exporter(
            opentelemetry_otlp::new_exporter()
                .tonic()
                .with_endpoint(opentelemetry_endpoint.as_str())
                .with_metadata(metadata.clone())
                .with_tls_config(
                    ClientTlsConfig::new().domain_name(
                        opentelemetry_endpoint
                            .host_str()
                            .expect("OTEL_ENDPOINTshould have a valid host"),
                    ),
                ),
        )
        .install_batch(opentelemetry::runtime::Tokio)
}

#[tokio::main]
async fn main() -> anyhow::Result<()> {

    let mut metadata = MetadataMap::with_capacity(2);

    metadata.insert(
        "x-honeycomb-team",
        "...honeycomb api key...".parse().unwrap(),
    );

    metadata.insert("x-honeycomb-dataset", "my-api".parse().unwrap());

    let tracer = init_tracer(&metadata).expect("failed to instantiate opentelemetry …

正如标题所述，我有一些客户端应用程序将指标、跟踪和日志发送到 opentelemtry 收集器，然后收集器应将提到的信号导出到 jaeger 实例。

由于某种原因，它失败了，并出现了一个不太明显的错误，我陷入了困境。

这是 Docker 的组成：
