Spring makes building a reliable application much easier thanks to its declarative transaction management. It also supports programmatic transaction management, but that’s not as common. In this article, I want to focus on the declarative transaction management angle, since it seems much harder to debug compared to the programmatic approach. This is partially true. We can’t put a breakpoint on a transactional annotation. But I’m getting ahead of myself.

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.

You’ve likely heard the term Observability lately. There’s a fundamental change taking place in the Monitoring space, and Observability is behind it. Observability itself is a broad topic, so in this post we’ll talk about what it means to move from Application Performance Monitoring to Application Performance Observability.

I always tell people "Observability is not logs, metrics, and traces! Observability is empowering your team to ask questions." That's very aspirational and sounds good, but it's not at all clear. I now have a self-contained story that perfectly explains it!

Being on call is challenging. It’s signing up to be operating complex services in a totally interruptible manner, at all hours of the day or night, with limited context. It’s therefore critical to have proper on-call on-boarding procedures, offer continuous training sessions, and continuously improve documentation. We also need to make sure people feel safe by providing ways to reduce their stress, and make room for questions to surface all sorts of uncertainties around our operations.

Big news: I can finally stop pointing anyone who asks about Honeycomb’s story for frontend observability to Emily’s blog post from 2017 on “Instrumenting Page Loads with Honeycomb.” (It was a great post, don’t get me wrong, but I don’t think any of us knew it would bear such weight for so long.) I am ecstatic to announce that we have released a new whitepaper called “Getting Started With Honeycomb Client-Side Instrumentation for Browser Applications,” wri
