One of our core values at Helios is to eat our own dog food (or for those of you who want to keep it classy, “drink our own champagne”). While this is a known best practice among many product development teams, it’s even more important when working on tools meant to be used on an ongoing basis by developers.

Technologies such as serverless computing frameworks and CI/CD automation tools help accelerate software development lifecycles (SDLC) to give development teams a competitive edge in the marketplace. Armed with these technologies, teams can deploy and innovate faster and more frequently by automating repetitive tasks and eliminating the need to manage or provision servers.

In our Configuring OpenTelemetry in Ruby blog post, we showed how to configure OpenTelemetry in a Ruby on Rails backend. In this post, we’ll cover how to configure OpenTelemetry in the front-end JavaScript in order to measure performance of browser and mobile devices and how to configure distributed tracing to work across the frontend and back end telemetry collection. Let’s dive in!

Ah, I too have wondered about this. TL;DR: The Resource says what program is sending these spans and where it’s running. You can skip it if you define OTEL_SERVICE_NAME in the environment. When I’m setting up tracing (for instance, in a Node.js app), I have to create a Resource object in order to set up the OpenTelemetry SDK: If I don’t define that resource parameter, then tracing will still work. But my spans will show up with aservice.name of unknown_service:node.

The promise of OpenTelemetry is that it can help you avoid vendor lock-in by allowing you to instrument your applications once, then send that data to any backend of your choice. This post shows you exactly how to do that with code samples that configure your application to send telemetry data to both Honeycomb and New Relic.

Written by @thetomzach @ Aspecto. In this guide, you’ll learn what Jaeger tracing is, what distributed tracing is, and how to set it up in your system. We’ll go over Jaeger’s UI and touch on advanced concepts such as sampling and deploying in production. You’ll leave this guide knowing how to create spans with OpenTelemetry and send them to Jaeger tracing for visualization. All that, from scratch.

OpenTelemetry (OTel) is emerging as the industry standard for system observability and distributed tracing across cloud-native and distributed architectures. But where do developers fit in? With OTel’s main use case focusing on production monitoring and observability, I find that many developers are still not fully familiar with OTel. Others believe it is more of a tool for DevOps/SRE.

Ah, good question! TL;DR: store the start time of the span, and then create the span on the new page. Usually, you want to start a span, do some work, and then end the span. The whole span gets sent to your OpenTelemetry collector (and thence to Honeycomb) when you end it. But when a page load happens, that span object is lost. Honeycomb never hears about it becausespan.end()wasn’t called. How can we deal with this? Create the span only on the new page, where you can end it. But!

Microservices are powerful architectures. Yet, they are complicated ones as well. Microservices enable engineering departments to scale faster than ever, but this speed comes at the price of developer confidence. When developing microservices, it is hard for developers to understand how different services interact with each other and why a certain event occurred when and where it did.
