Tracking system request with Open telemetry, sentry and Go-in Golang language

Use Open Telemetry Tracing system in sentry to understand what’s going on in the backend.

Go-Micro Plugin for Using Opentelemetry in Go-Micro

Add tracking open telemetry in Go-micro

python

import  SDKTrace "go.opentelemetry.io/otel/sdk/trace" sentryOtel
"github.com/getsentry/sentry-go/otel"

Add Tracer in main.go

tp := SDKTrace.NewTracerProvider(  SDKTrace.WithSpanProcessor(sentryOtel.NewSentrySpanProcessor()),
) otel.SetTracerProvider(tp) otel.SetTextMapPropagator(sentryOtel.NewSentryPropagator())
entity.TracerMain = tp.Tracer(service)

Add Tracking system in service

srv := micro.NewService(  ...  //Tracking
micro.WrapClient(opentelemetry.NewClientWrapper(opentelemetry.WithTraceProvider(tp))),
micro.WrapCall(opentelemetry.NewCallWrapper(opentelemetry.WithTraceProvider(tp))),
micro.WrapHandler(opentelemetry.NewHandlerWrapper(opentelemetry.WithTraceProvider(tp))),
micro.WrapSubscriber(opentelemetry.NewSubscriberWrapper(opentelemetry.WithTraceProvider(tp))),)

Sentry support OpenTelemetry

With Sentry’s OpenTelemetry SDK, an OpenTelemetry Span becomes a Sentry Transaction or Span. The first Span sent through the Sentry SpanProcessor is a Transaction, and any child Span gets attached to the first Transaction upon checking the parent Span context. This is true for the OpenTelemetry root Span and any top level Span in the system. For example, a request sent from frontend to backend will create an OpenTelemetry root Span with a corresponding Sentry Transaction. The backend request will create a new Sentry Transaction for the OpenTelemetry Span. The Sentry Transaction and Span are linked as a trace for navigation and error tracking purposes.

import (
"go.opentelemetry.io/otel" sdktrace "go.opentelemetry.io/otel/sdk/trace"
"github.com/getsentry/sentry-go"
"github.com/getsentry/sentry-go/otel" //...)sentry.Init(sentry.ClientOptions{
    Dsn: "__DSN__", EnableTracing:
    true, TracesSampleRate: 1.0, Debug: true,
})tp :=
sdktrace.NewTracerProvider(sdktrace.WithSpanProcessor(sentryotel.NewSentrySpanProcessor()),)otel.SetTracerProvider(tp)otel.SetTextMapPropagator(sentryotel.NewSentryPropagator()

Capture data with open telemetry

Creating Spans

ctx, span := tracer.Start(ctx, "hello-span")defer span.End()

Span Attributes

Attributes are keys and values that are applied as metadata to your spans and are useful for aggregating, filtering, and grouping traces. Attributes can be added at span creation, or at any other time during the lifecycle of a span before it has completed.

span.SetAttributes(attribute.Bool("isTrue", true), attribute.String("stringAttr", "hi!"))

Events

An event is a human-readable message on a span that represents “something happening” during it’s lifetime.

span.AddEvent("some things happened here!")

In this case we can easily use sentry capture message too.

Set span status

A status can be set on a span, typically used to specify that there was an error in the operation a span is tracking — .Error

span.SetStatus(codes.Error, "operationThatCouldFail failed")
