SLOs—or Service Level Objectives—can be pretty powerful. They provide a safety net that helps teams identify and fix issues before they reach unacceptable levels and degrade the user experience. But SLOs can also be intimidating. Here’s how a lot of teams feel about them: We know we want SLOs, we’re not sure how to really use them, and we don’t know how to debug SLO-based alerts.

In this post, we’ll look at how you can use OpenTelemetry to monitor your unit tests and send that data to Honeycomb to visualize. It’s important to note that you don’t need to adopt Honeycomb, or even OpenTelemetry, in your production application to get the benefit of tracing. This example uses OpenTelemetry purely in the test project and provides great insights into our customer’s code.

So many of the best and most promising managers I know have left management roles for senior IC roles since 2018, and as someone who has to hire managers, this creates a supply problem for me. Sincerely though, I also observe that a truly staggering number of Honeycomb’s most effective, most admired senior ICs are former managers, and while they seem quite happy and I wouldn’t wish them back to their old roles, the fact that all of these smart, thoughtful, driven, emotionally intelligent people all chose to leave the same high-paying, respectable role must mean something.

The scenario: you want to see distributed traces, maybe for your web app. You’ve set up an OpenTelemetry collector to receive OTLP traces in JSON over HTTP, and send those to Honeycomb (how to do that is another post, and we’ll link it here when it’s up). The question: does it work? Let’s test the collector and its connection to Honeycomb by sending a test span.

Honeycomb Play is an interactive sandbox that lets users explore Honeycomb’s data-enriched UI through a guided scenario. The hands-on experience takes a deep dive into how Honeycomb enables you to identify issues, assess their impact, and diagnose their causes for remediation.

Observability is about understanding systems, which means more than just production. Moving from logs to tracing and showing causality can be done locally, as well. We can give developers the same superpowers that SREs have: observability-driven development. 

If you let all the power drift over to the engineering managers, pretty soon it doesn’t look so great to be an engineer. Now you have people becoming managers for all the wrong reasons, or everyone saying they want to be a manager, or engineers tuning out and turning in their homework (or quitting). We all want autonomy and impact, we all crave a seat at the table. You need to work harder to save those seats for non-managers.

People use “observability team” as a catchall basket for all kinds of things these days—from cutting-edge tech to truly heinous hacks. Eh, it is what it is. The industry may be in a roiling state of massive flux, but I’m cautiously excited about the changes beginning to take shape and emerge from the muck. And I definitely think it’s worth spending some time talking about what observability teams can and should be.

Google’s Core Web Vitals (CWV) are used to rank the performance of mobile sites or pages. It’s easy to see when your CWV scores are low, but it’s not always clear exactly why that’s happening. In Honeycomb’s new guide, Tracking Core Web Vitals with Honeycomb and Vercel, you can learn how to capture, analyze, and debug your real-world CWV performance using a free Honeycomb account.

We’ve wondered, in the past, what new engineers think about how we do things at Honeycomb. This time, we asked! Meet Elliott and Reid, two of our engineers that recently hit their 90 day mark. Along with the title question, we also asked about their prior companies, how we differ, and what surprised them most about working here.

One of the reasons that OpenTelemetry is great at doing this is that a lot of the common attributes you may find on a span are given standard names, so the systems receiving the data to visualize them don’t need to know the specifics of your system. This is really a superpower of OpenTelemetry, as it gives a level playing field for consumers of that information—meaning that you, as a developer, can forget about vendor-specific things.

If you get CI/CD right, a lot of other critical functions, behaviors, and intuitions align to be comfortably successful and correct with minimal effort. If you get it wrong, you will spend countless cycles chasing pathologies. It’s like choosing to eat your vegetables every day vs choosing a diet of cake and soda for fifty years, then playing whack-a-mole with all the symptoms manifesting on your poor, moldering body.
