otlp grpc jaeger golang怎么写-DPDK中文网

下面是一个使用OTLP gRPC进行跟踪的Golang示例代码，其中将Jaeger Exporter和OTLP gRPC Exporter绑定到OpenTelemetry SDK：

package main

import (
	"context"
	"log"

	"go.opentelemetry.io/otel/api/global"
	sdktrace "go.opentelemetry.io/otel/sdk/trace"
	"go.opentelemetry.io/otel/exporters/jaeger"
	"go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc"
)

func main() {
    // 创建 Jaeger Exporter
    endpoint := "jaeger-collector:14250"
    jaegerExporter, err := jaeger.NewRawExporter(jaeger.WithCollectorEndpoint(jaeger.WithEndpoint(endpoint)))
    if err != nil {
        log.Fatalf("Failed to create Jaeger exporter: %s", err.Error())
    }

    // 创建 OTLP gRPC 客户端
    otlpCollectorAddr := "localhost:4317"
    creds := credentials.NewClientTLSFromCert(nil, "")
    otlpChannel, err := grpc.Dial(otlpCollectorAddr, grpc.WithTransportCredentials(creds))
	if err != nil {
        log.Fatalf("Failed to create gRPC channel: %s", err.Error())
	}
	defer otlpChannel.Close()

	// 创建 OTLP gRPC Exporter
	exporter := otlptracegrpc.NewRawExporter(
		otlptracegrpc.WithInsecure(),
	    otlptracegrpc.WithEndpoint(otlpCollectorAddr),
	)

	// 将 Jaeger Exporter 和 OTLP gRPC Exporter 绑定到 OpenTelemetry SDK
	batchSpanProcessor := sdktrace.NewBatchSpanProcessor(exporter)
	tp := sdktrace.NewTracerProvider(sdktrace.WithBatcher(batchSpanProcessor))
	global.SetTraceProvider(tp)

	// 创建和使用 OpenTelemetry Tracer
	tracer := global.Tracer("example")
	ctx, span := tracer.Start(context.Background(), "foo")
	defer span.End()

    // 记录一些跟踪事件
    span.AddEvent(ctx, "event1", kv.String("key1", "value1"))
    span.AddEvent(ctx, "event2", kv.String("key2", "value2"))

    // 记录一些属性
    span.SetAttributes(kv.String("attribute1", "value1"), kv.Int64("attribute2", 123))

    log.Printf("Hello, OTLP gRPC and Jaeger!")
}

请注意，您需要在项目中导入以下依赖项：

import (
	"context"
	"log"

	"go.opentelemetry.io/otel/api/global"
	sdktrace "go.opentelemetry.io/otel/sdk/trace"
	"go.opentelemetry.io/otel/exporters/jaeger"
	"go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc"
)

同时，您还需要安装gRPC和OpenTelemetry库。
