Distributed tracing with OpenTelemetry in Go is a powerful technique for tracking the flow of requests through a distributed system. It allows you to visualize the path of a request as it travels through different services, and to identify any bottlenecks or errors that may be occurring.

import ("context""fmt""io""go.opentelemetry.io/otel""go.opentelemetry.io/otel/attribute""go.opentelemetry.io/otel/codes""go.opentelemetry.io/otel/sdk/trace")func main() {// Create a new tracer provider.tp := trace.NewTracerProvider()otel.SetTracerProvider(tp)// Create a new tracer.tracer := otel.Tracer("my-tracer")// Create a new context with the tracer.ctx := context.Background()// Start a new span.ctx, span := tracer.Start(ctx, "my-span")// Do some work.fmt.Println("Hello, world!")// Add some attributes to the span.span.SetAttributes(attribute.String("key1", "value1"),attribute.Int("key2", 123),)// End the span.span.End()}

Distributed tracing is especially useful for debugging complex systems, as it can help you to identify the root cause of a problem. It can also be used to improve the performance of a system by identifying bottlenecks and optimizing the flow of requests.

In this article, we will explore the basics of distributed tracing with OpenTelemetry in Go. We will show you how to create a tracer, start a span, add attributes to a span, and end a span. We will also provide some examples of how distributed tracing can be used to debug and optimize a system.

Distributed tracing is a powerful technique for tracking the flow of requests through a distributed system. It allows you to visualize the path of a request as it travels through different services, and to identify any bottlenecks or errors that may be occurring. OpenTelemetry is a vendor-neutral framework for collecting and managing telemetry data, including traces. It provides a set of libraries that can be used to instrument your code and collect tracing data.

  • Observability: Distributed tracing provides observability into the behavior of your system. It allows you to see how requests are flowing through your system, and to identify any bottlenecks or errors that may be occurring.
  • Debugging: Distributed tracing can be used to debug complex systems. By visualizing the flow of requests through your system, you can identify the root cause of a problem.
