It’s been a minute since our last Feature Focus, and we have a bit of catching up to do! I’m happy to report we’ll resume monthly updates next month, but until then, please enjoy this super-sized winter digest of what we’ve been up to at Honeycomb.

When you’re just getting started with observability, a proof of concept (POC) can be exactly what you need to see the positive impact of this shift right away. Coveo, an intelligent search platform that uses AI to personalize customer interactions, used a successful POC to jumpstart its Honeycomb observability journey—which has grown to include 10,000+ machine learning models in production at any one time.

Your API Key (in the x-honeycomb-team header) tells Honeycomb where to put your data. It specifies a team and an environment. Then, Honeycomb figures out which dataset to put each event in, based on the service.name field in the event. Except…

When we work at it, professionals are pretty good at analysis. We can break down a simple system, look at its parts and their relations, and master it. Given enough time and teammates, we can analyze a very complicated system and fix it when it breaks. But complex systems don’t yield to analysis. We have to add another skill: sense-making.

So you're used to debugging systems using a distributed trace, but your system is about to introduce a message queue—and that will work the same… right? Unfortunately, in a lot of implementations, this isn't the case. In this post, we'll talk about trace propagation (manual and OpenTelemetry), W3C tracing, and also where a trace might start and finish.

Distributed tracing enables you to monitor and observe requests as they flow through your distributed systems to understand whether these requests are behaving properly. You can compare tiny differences between multiple traces coming through your microservices-based applications every day to pinpoint areas that are affecting performance. As a result, debugging and troubleshooting are simpler and faster. No one has to guess or spend countless hours researching possible causes for issues, like you would if traditional logging methods were your only resource.

Imagine a universe in which a massively multiplayer online role-playing game (MMORPG) sets Guinness World Records for the size of its online space battles—and that game is built on 20-year-old code. Well, imagine no more. Welcome to the world of EVE Online, where hundreds of thousands of players interact across 7,800+ star systems and participate in more than one million daily market transactions. As you might guess, updating and maintaining this codebase without interrupting game play could pose quite a challenge.

Growing pains can be a natural consequence of meteoric success. We were reminded of that in our recent panel discussion with SumUp’s observability engineering lead, Blake Irvin, and senior software engineer Matouš Dzivjak. They shared how SumUp’s rapid growth spurt compelled them to change their resolution process—both logistically and culturally—to ensure a service level quality that reflects their customer obsession.

When I joined Honeycomb two years ago, we were entering a phase of growth where we could no longer expect to have the time to prevent or fix all issues before things got bad. All the early parts of the system needed to scale, but we would not have the bandwidth to tackle some of them graciously. We’d have to choose some fires to fight, and some to let burn.

For a long time at Honeycomb, we envisioned using the tracing data you send us to generate a service map. If you’re unfamiliar, a service map is a graph-like visualization of your system architecture that shows all of its components and dependencies. We didn’t want it to be a static service map, though—the kind you’d view once before going “huh, neat”—and then never looking at it again. We wanted to build an actually useful, uniquely Honeycomb-y service map that could become an integral part of your team’s observability workflow.

In January 2022, Honeycomb kicked off a one year experiment to have an employee sit as a voting board member on the board of directors. I became that board member in July 2022. As the experiment comes to a close, I want to share some of my reflections.
