Product managers (PMs) need to make fast, confident decisions about what to build, fix, and improve based on user behavior within their application. But in practice, collecting the user insights they require is rarely straightforward. Recent updates to Datadog Product Analytics address this challenge. Product Analytics adds structure to autocaptured data and makes analysis easier to interpret, reuse, and share, helping PMs move from questions to answers without relying on SQL or engineering.

Event-driven systems are great at decoupling services, but they also make incidents harder to untangle. A single user request can turn into dozens (or thousands) of messages, multiple consumers, retries, and delayed acknowledgments. If your tracing only tells you that a message was sent or received, you still have to guess which upstream request produced the message, whether a batch publish fanned out cleanly, and where queue time is accumulating.

When to use JavaScript or CSS in frontend projects is a matter of continued debate among many frontend developers. JavaScript is often the default choice for frontend development, as it offers a robust collection of libraries custom-made for creating advanced UI features, such as data-based visualizations or complex animations. But JavaScript also comes with tradeoffs, particularly when it comes to performance, accessibility, and code complexity.

Organizations are increasingly using agentic AI applications powered by large language models (LLMs) to automate analysis, decision-making, and operational workflows. As these AI agents take on more responsibility, they gain access to internal tools and services and can interact with them in unintended ways.

This article is part of our series on how Datadog engineering teams use LLM Observability to build, monitor, and improve AI-powered systems. At Datadog, we’re always looking for ways to make complex data easier to explore.

In PostgreSQL, the EXPLAIN ANALYZE statement gives you a detailed report of what actually happens when you execute a query. This kind of information is important for troubleshooting slow queries, but using EXPLAIN ANALYZE to collect this data is often challenging in a production environment. Datadog Database Monitoring now supports automatic collection of EXPLAIN ANALYZE plans for PostgreSQL, enabling you to easily capture execution details that help you troubleshoot slow queries.

Generative AI enables teams to write and ship code faster than ever. But current methods for testing and quality assurance have not evolved to match the new pace and scale of deployments. Manual and deterministic testing paths quickly become obsolete when new features are released, and they fundamentally can’t test AI outputs, leaving a massive untested surface area. To keep up, teams need new testing methods that can define what goals users have, and ensure that their outcomes match.

Teams can use Datadog Real User Monitoring (RUM) and RUM without Limits to get full visibility into the frontend health of their applications while retaining only the sessions that contain critical problems that affect the end-user experience. But application errors or slowness often result from backend issues, such as database bottlenecks. To diagnose these issues, you need to correlate the frontend data from RUM with the backend data from Datadog Application Performance Monitoring (APM).

As organizations grow their cloud environments and branch office networks, maintaining reliable connectivity and application performance becomes more complex. VeloCloud SD-WAN provides dynamic, policy-based routing to help ensure that your connectivity is dependable and cost-efficient, and that your applications perform consistently.

This article is part of our series on how Datadog’s engineering teams use LLM Observability to iterate, evaluate, and ship AI-powered agents. In this first story, the Graphing AI team shares how they instrumented their widget- and dashboard-generation agents with LLM Observability to detect regressions and debug failures faster. Visibility into how large language model (LLM) applications behave in real time is essential for building reliable AI-driven systems at Datadog.
