Autonomously monitor for impactful degradations with Bits Detection
Learn how Bits Detection autonomously monitors for impactful degradations and keeps endpoint coverage current as services, endpoints, and dependencies change.
Building Agents that Don't Break Themselves
Building agents is fun. Rebuilding agents that break themselves… less so. A lot of Fly people are building agents with less of a penchant for self-destruction by teaching their agents to do anything risky in a Sprite. You get an agent that stays alive long enough to actually use its snazzy self-impr...
Search and act across Datadog to resolve issues faster with Bits Chat
Bits Chat lets you search, visualize, and take action across Datadog using natural language, without losing context or switching tools.
Monitor Claude Enterprise activity with Datadog Cloud SIEM
Use the Datadog Claude Compliance API integration to monitor Claude Enterprise activity, detect risky behavior, and investigate events.
Why AI code optimization needs production-grounded benchmarks
Learn how Datadog’s DODO optimizer grounds AI-driven code optimization in live production telemetry, using CPU profiles and real call samples to generate accurate benchmarks and find meaningful speedups in mature services.
Give your AI agents live Datadog access from the command line
Learn how Pup CLI gives AI agents secure, token-efficient access to the full Datadog platform from the command line, with no long-lived API keys required.
Introducing Bits Agent Builder: Build agentic workflows for alert response and remediation
Learn how you can build custom AI agents to automate complex operational tasks.
When failover isn’t safe: Building high-availability PostgreSQL on Kubernetes
During a reliability gameday, Datadog engineers discovered that their PostgreSQL clusters couldn’t safely fail over. Here’s how the team redesigned them for high availability using Patroni and synchronous replication.
Fixing my ridiculous fridge with a tiny Funnel site
I built a tiny transit dashboard for my fridge. Tailscale Funnel made it easy to share—and reminded me what belongs on the public internet.
From single pull requests to full software packages: Detecting malicious code at scale
By combining stacked LLM evaluations with tool-driven investigation, we scaled malicious code detection from pull requests to dependency packages without sacrificing accuracy or cost control.
From Kubernetes Dashboard to Headlamp: Understanding the Transition
For many people, Kubernetes Dashboard was their first window into Kubernetes. It offered a simple visual way to see what was running in a cluster, inspect resources, and build confidence without relying on the command line. For years, it helped developers, students, and operators make sense of Kuber...
A deep dive into AWS data perimeter misconfigurations
Explore how threat emulation can help you find gaps in your AWS data perimeter policies, then learn which organization-level policies can close them.
Migrate to Azure Managed Redis with Datadog and Eden
Migrate to Azure Managed Redis by using Datadog and Eden to establish performance baselines, execute and validate cutovers, and monitor cache health.
How we cut Spark compute costs by 44% with agentic AI and Datadog Jobs Monitoring
See how agentic AI and Jobs Monitoring helped us reduce Spark job duration, infrastructure costs, and the time spent correlating root causes.
How a unified data model improves feature flag rollout decisions
Learn how stitched-together tooling can be a bottleneck for shipping at scale, and how a unified platform can bring together product signals for teams to observe their entire stack.
Monitor LLM routing with the Kubernetes Inference Extension
Learn how to use inference-aware routing for your LLM workloads in Kubernetes, and how to monitor performance with Datadog.
Beyond code generation: rethinking engineering productivity in the age of AI agents
How Dropbox is moving from AI tools that assist engineers to agentic systems that can execute scoped tasks, and how we’re building platforms to support those workflows.
Canada’s Bill C-22 and the security cost of collecting more data
Bill C-22 would push secure services to collect more data, retain more metadata, and build new access paths. That’s bad for privacy, and bad for security.
Reconciling the Past: Correcting Records for Unfixed Kubernetes CVEs
The Kubernetes project relies on transparency to empower cluster administrators and security researchers. One important way we do that is by publishing CVE records into the Common Vulnerabilities and Exposures database. As part of our ongoing effort to mature the official Kubernetes CVE Feed , we ha...
Introducing Nova, our internal platform for coding agents
Nova lets engineers run multiple coding sessions in parallel and lets internal systems use AI agents as part of automated workflows.
