The management of modern software environments hinges on the three so-called “pillars of observability”: logs, metrics and traces. Each of these data sources provides crucial visibility into applications and the infrastructure hosting them. For many IT operations and site reliability engineering (SRE) teams, two of these pillars — logs and metrics — are familiar enough.

Miss O11y is delighted to welcome our newest band member: Martin Thwaites! Martin has been a member of the Honeycomb user community practically since its inception. He is a UK-based consultant who specializes in helping teams scale up and tackle challenging business problems, and a long-time contributor to the Azure and.NET communities. We think he looks ✨amazing✨ in a tiara.

OpenTelemetry has been getting a lot of attention in the observability field. Moreover, in StackState’s latest release, we added support for OpenTelemetry traces. Melcom van Eeden, software developer at StackState, was one of our developer champions who made this possible. In addition to joining us on this episode of StackPod, he wrote a blog post on how to leverage OpenTelemetry with StackState and he recorded a tutorial video about the topic.

Ah, good question! TL;DR: Trace instead of log. Traces show connection, performance, concurrency, and causality. Logs are the original observability, right? Back in the day, I did all my debugging with `printf.` Sometimes I still write `console.log(“JESS WAS HERE”)` to see that my code ran. That’s instrumentation, technically. What if I emitted a “JESS WAS HERE” span instead? What’s so great about a span in a trace? Yeah, and so do logs in any decent framework.

Your applications most likely consist of multiple components. These components could be written in different languages, with each individually instrumented with Sentry’s SDK. The goal of our tracing solution is to make sure developers get a full picture of the data captured within their tech stack. Tracing allows you to follow a request from the frontend all the way to your backend application and back.

Before we dive into the Collector, let’s cover the components that make up the OpenTelemetry project. If you missed it, our post What is OpenTelemetry gives a high level introduction to OpenTelemetry and the key components of OpenTelemetry project: The OpenTelemetry collector is optional when using a SaaS service like Scout. Even so, knowing what the Collector can do and when to use it is helpful to understand.

OpenTelemetry and Jaeger are both open-source projects under Cloud Native Computing Foundation. In this article, let us understand the key concepts involved in both projects, their features, and their differences. OpenTelemetry is a vendor-agnostic instrumentation library. It provides a set of tools, APIs, and SDKs to create and manage telemetry data(logs, metrics, and traces). Jaeger is an open-source tool focused on distributed tracing of requests in a microservice architecture.
