In the early hours of December 12, 2025, Trello experienced a disruption that affected teams around the world. Users began reporting that boards would not load, workspaces were inaccessible, and error messages appeared without warning. For a period of time, Trello’s official status page continued to show normal operations, even as real world usage indicated otherwise.

Picture this: You’ve spent hours perfecting your React component. The animations are smooth, the responsive design works flawlessly, and you’re ready to test the user flow. You click “Submit” and… nothing happens. Or worse, you get a cryptic CORS error. The problem? Your backend isn’t running. Again.

Picture this, your observability tool already nails the basics like request rates, latency and memory usage, but you need more insight. Think user churn rates, engagement spikes, or even how many carts get abandoned mid-checkout. That’s where OpenTelemetry steps in, providing a way to track those critical custom metrics with ease.

Once more in this series, we’re moving into areas where I’m not entirely comfortable. I haven’t built a PHP plugin and web page, ever. However, we’re going to put the LLM/AI and associated agents to work on this task. As with so much else when working with AI, it all starts with the prompt, so let’s go there.

So you've built a client application and you've started sending telemetry. The information sent back by this client is vital to you, and one of the first things you care about is capturing and reporting errors. There are at least two ways to report error details in OpenTelemetry. Web applications generally place exceptions in trace spans as span events, and mobile applications send exceptions as log messages instead.

AI tools have seen a meteoric rise in the workplace. What was once the domain of highly specialized tech roles is now commonplace: Ivanti’s 2025 Technology at Work Report found that 42% of office workers say they’re using gen AI tools, like ChatGPT, at work — up 16 points from the previous year. The catch? These productivity gains happen under the table. Among those who reported using gen AI tools, 46% say that some (or all) of the tools they use are not employer-provided.

This blog is based on Haylee Millar's talk at the Symfony 2024 conference. Haley is a Product Engineer at Upsun. We utilized AI tools for transcription and to enhance the structure and clarity of the content. When faced with an aging system that needs new features, many development teams find themselves at a crossroads. Do you patch the old system and risk technical debt, or do you take the leap into microservices architecture?
