In this article, we will implement distributed tracing for a Golang application with three microservices. To implement distributed tracing, we will be using open-source solutions - SigNoz and OpenTelemetry, so you can easily follow the tutorial.

OpenTelemetry can only help in generating the telemetry data. In order to store, and analyze that data, you need to choose a backend analysis tool. In this article, we will monitor collected data from gRPC calls with SigNoz. SigNoz is a full-stack open-source APM tool that provides metrics monitoring and distributed tracing. It is built to natively support OpenTelemetry data formats. Hence, it’s a great choice for a backend analysis tool to combine with OpenTelemetry. On a side note, OpenTelemetry provides you the freedom to select a backend analysis tool of your choice.

In this video, we demonstrate how to implement OpenTelemetry NextJS libraries for a sample NextJS application and then visualize the collected data in SigNoz. More about SigNoz: SigNoz - Monitor your applications and troubleshoot problems in your deployed applications, an open-source alternative to DataDog, New Relic, etc. Backed by Y Combinator. SigNoz helps developers monitor applications and troubleshoot problems in their deployed applications. SigNoz uses distributed tracing to gain visibility into your software stack.

SigNoz provides query and visualization capabilities for the end-user and comes with out-of-box charts for application metrics and traces. Now let’s get down to how to implement OpenTelemetry in your Elixir application.
