This post takes a closer look at how Sentry’s AI Code Review actually works. As part of Seer, Sentry’s AI debugger, it uses Sentry context to accurately predict bugs. It runs automatically or on-demand, pointing out issues and suggesting fixes before you ship. We know AI tools can be noisy, so this system focuses on finding real bugs in your actual changes—not spamming you with false positives and unhelpful style tips.

By Doreen Jacobi, DERDACK / SIGNL4 It is that time of the year again. Time to reflect and look back at 2025. And I find myself thinking less about platforms and features – and more about the people behind them. The engineers who pick up the phone at 2 a.m. The operators who make judgment calls with incomplete information. The responders who keep systems running when everything feels urgent. If this year taught us anything, it’s this: technology can detect the problem, but people solve it.

The Valkey JSON module implements native JSON data type support within Valkey, allowing users to efficiently store, query, and modify complex, nested JSON data structures directly. This overcomes previous architectural complexities, such as needing to serialize entire documents as strings or flatten data into hashes, by providing native handling for nested data models.

Connecting nearly a billion professionals is no small feat. It requires an infrastructure that puts the user experience above everything else. At LinkedIn, this principle created a massive engineering challenge: delivering a fast, consistent experience across various use cases, from the social feed to real-time messaging and enterprise tools.

Regular monitoring practices can emphasize application response time, but queue time is also often an early and important warning sign. If it rises, you’ll quickly see downstream effects: tail latency, timeouts, and error spikes. This means that this metric can give you a head start tackling app issues before they become user problems. In this post, we’ll discuss queue time, how things can go off track, and practical steps to turn it around.

If you're using TrueFoundry to manage your LLM traffic, you can now send those traces directly to Last9 and view them alongside your existing infrastructure telemetry.

Fleet, Rancher’s built-in GitOps engine, is designed to scale up to thousands of clusters. However, “how far” can it scale in a real world scenario, you might ask? Earlier this year, we wrote about the Fleet benchmark tool and we made a few discoveries that were very instructive, especially concerning resource consumption and its impact on deployments’ performances.

Highlights of another laudable year of customer-centric collaboration The integration of Elastic’s capabilities, including vector databases and context engineering, with AWS services helps customers build intelligent, scalable, and secure applications faster and with greater flexibility. Our ongoing collaboration has resulted in another year of notable innovation with AWS. This blog highlights our continued collaboration with AWS throughout 2025 to help you capitalize on the power of AI.

This year’s Gartner IT Infrastructure, Operations and Cloud Strategies Conference made one thing abundantly clear: the industry is moving beyond reactive monitoring and isolated dashboards toward autonomous, outcome-driven IT operations. While AI and agentic automation dominated keynotes and vendor messaging, conversations on the show floor reflected a more grounded reality.

It’s 5:14am, and I wake up to the squawking geese sound of my PagerDuty alert (anyone else have this sound? No?). I’m four months into working for my new team as a junior software engineer, and this is my first time being paged in the middle of the night. Most software engineers probably dread this moment, but I kind of love it. Agile ceremonies and Jira tickets suddenly don’t matter, and you’re fully focussed on stopping a customer-impacting fire.
