opentelemetry-collector 设置jaeger

一、修改docker挂载的设置文件

1. nano /root/otelcol-config.yaml
2. ==========================================
3. receivers:
4.   otlp:
5.     protocols:
6.       grpc:
7.         endpoint: 0.0.0.0:4317
8.       http:
9.         endpoint: 0.0.0.0:4318
10. exporters:
11.   debug:
12.     verbosity: detailed
13.   otlp/jaeger: # Jaeger supports OTLP directly
14.     endpoint: 192.168.31.161:4317
15.     tls:
16.       insecure: true  
17. service:
18.   pipelines:
19.     traces:
20.       receivers: [otlp]
21.       exporters: [otlp/jaeger]
22.     metrics:
23.       receivers: [otlp]
24.       exporters: [debug]
25.     logs:
26.       receivers: [otlp]
27.       exporters: [debug]
28. ==========================================

上面设置中要特别注意：insecure: true  关闭Grpc Https验证。
下面我们准备两个项目：demoA(5000)和demoB(5001)，在demoA发起http调用demoB

demoA：Program.cs

1. using OpenTelemetry.Exporter;
2. using OpenTelemetry.Logs;
3. using OpenTelemetry.Metrics;
4. using OpenTelemetry.Resources;
5. using OpenTelemetry.Trace;
8. var builder = WebApplication.CreateBuilder(args);
10. #region OpenTelemetry
11. var serviceName = "demoA";
12. var serviceVersion = "1.0.0";
14. builder.Services.AddOpenTelemetry()
15.     .ConfigureResource(resource => resource.AddService(
16.         serviceName: serviceName,
17.         serviceVersion: serviceVersion))
18.     .WithTracing(tracing => tracing
19.         .AddSource(serviceName)
20.         .AddAspNetCoreInstrumentation()
21.         .AddHttpClientInstrumentation()
22.         .AddOtlpExporter(options =>
23.         {

35. builder.Logging.AddOpenTelemetry(options => options
36.     .SetResourceBuilder(ResourceBuilder.CreateDefault().AddService(
37.         serviceName: serviceName,

42.         options.Protocol = OtlpExportProtocol.HttpProtobuf;
43.     }));
44. #endregion
46. // Add services to the container.
47. builder.Services.AddHttpClient();
49. builder.Services.AddControllers();
50. // Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle

57. if (app.Environment.IsDevelopment())
58. {
59.     app.UseSwagger();
60.     app.UseSwaggerUI();
61. }
63. app.UseAuthorization();
