CUPED (Controlled-experiment Using Pre-Experiment Data) is a powerful tool that can reduce metric variance and help teams obtain precise experiment results with less data. However, the difference between an experiment’s CUPED-adjusted lift and raw lift can be difficult to explain, especially when an experiment uses many pre-exposure metrics and subject properties. The CUPED adjustments visualization in Datadog Experiments breaks the difference into a sequence of specific adjustments.

Let’s say your team shipped a support agent last quarter. The launch demo went well, stakeholders were pleased, and everyone moved on. A few months later, things start to look off. Summaries of long conversations are truncated, and monitors show latency spikes on tool calls to the billing API. Your team’s first instinct is to ship fixes such as tweaking prompts or upgrading the model.

Sampling is a core skill that everyone who runs an observability pipeline at scale will learn. There are lots of tradeoffs within the various decisions you'll make from reducing bandwidth, CPU, and memory, to reducing costs and making the observability backend's performance better for users. Historically, there have only been three mechanisms, each with their own tradeoffs: However, there is a secret fourth option: adaptive tail sampling—which changes those tradeoffs.

Redgate Monitor now closes that gap. You can monitor reader nodes for the first time, alongside the writer node support we already had, and get a cluster-wide view that ties node-level health back to overall cluster performance.

Learn the difference between network redundancy and resilience, plus practical ways to improve failover, path diversity, and uptime.

It's 2 a.m. Monitoring alerts are firing, the on-call engineer is being paged, and customer reports are arriving faster than anyone can triage them. A bridge call opens. Infrastructure, network, application, and service desk teams hop on with different fragments of context. Meanwhile, executives want to know the scope, customer impact, and expected recovery time. This is not the moment to decide who is in command or how often updates should go out.

The U.S. government has cataloged over 1,700 active AI use cases, and nearly 90% of federal agencies are already using or planning to use AI. The European Commission has disclosed nearly 1,500 AI use cases across EU member states. With over 3,200 combined AI use cases cataloged across the US and EU, public sector IT leaders face an identical roadblock: traditional application delivery controllers were not designed to parse or throttle Layer 7 LLM payloads, leading to backend GPU exhaustion.

Our Results Daemon processes about 92 million messages a day. We recently rewrote it from Node.js to Go, and we let Claude Code write it. We wanted to know whether we could trust an agentic rewrite for a critical, high-throughput production service rather than a prototype. It shipped with zero incidents, a 70% reduction in running pods, and a lighter database load.

Storage rarely fails loudly. A pool fills. Latency climbs on one LUN. The first to notice is a user whose application timed out. The best storage monitoring software catches it earlier. It watches capacity, IOPS, latency and drive health across your arrays, which is what storage resource monitoring is for. In this blog, you will see: By the end you will know which one fits. Storage monitoring software tracks the health, capacity and performance of your IT storage.

Can you prove, on demand, which production systems were under continuous monitoring last quarter? Buyers, auditors, and insurers all ask a version of that question, and the answer decides contracts as often as audit findings. NIST compliance means aligning security controls and operations with standards from the National Institute of Standards and Technology, then holding evidence that the alignment stayed continuous. The frameworks are precise about outcomes and quiet about mechanics.
