OpenTelemetry Collector 404'ing at http://localhost:55681/v1/traces

编程问答 2022-07-29

问题描述

我已经浏览了官方的 Otel 收集器文档，并使用 Docker 和以下配置/代码文件运行收集器，但是当应用程序尝试 POST 到 /v1/traces 时，总是从收集器获得 404端点。我还尝试了各种代码示例 this post，在 macOS 和 Ubuntu 上运行收集器，使用旧版本，但都没有成功。甚至 curl -s -X POST 'http://localhost:55681/v1/traces 也会给出 404。这不再是正确的端点吗？它必须是一些简单的东西。 :)

docker run -it --rm -p 13133:13133 -p 14250:14250 -p 14268:14268 -p 55678-55681:55678-55681 -p 4317:4317 -p 8888:8888 -p 9411:9411 --name opentelemetry-collector -v "${PWD}/collector.yaml":/collector.yaml otel/opentelemetry-collector --config collector.yaml

Angular 应用中的 TypeScript

import { Injectable } from '@angular/core';
import { JaegerExporter,ExporterConfig } from '@opentelemetry/exporter-jaeger';
import { WebTracerProvider } from '@opentelemetry/web';
import { SimpleSpanProcessor,ConsoleSpanExporter } from '@opentelemetry/tracing';
import { CollectorExporterNodeConfigBase,CollectorTraceExporter } from '@opentelemetry/exporter-collector';

@Injectable({
  providedIn: 'root'
})
export class TracerService {

  public tracerProvider: WebTracerProvider;

  constructor() {
    this.tracerProvider = new WebTracerProvider();
    this.tracerProvider.addSpanProcessor(new SimpleSpanProcessor(new ConsoleSpanExporter()));

    let conf: CollectorExporterNodeConfigBase = {};
    const exporter = new CollectorTraceExporter(conf);
    this.tracerProvider.addSpanProcessor(new SimpleSpanProcessor(exporter));
    this.tracerProvider.register();
  }
}

Prometheus.yaml

global:
  scrape_interval: 15s # Default is every 1 minute.

scrape_configs:
  - job_name: 'collector'
    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
    static_configs:
      - targets: ['collector:9464']
