Telemetry-driven development: How to gain confidence in your coding agents' behavior with gcx and Grafana MCP
You’re about to click "Merge" on a PR, but you feel more anxious about it than you used to. Why? You did everything properly, by today’s standards: You used Claude to create a plan, giving it context from a GitHub issue and some Slack threads.

How NVIDIA Builds Open Models for the Age of AI
Bryan Catanzaro, VP of Applied Deep Learning Research at NVIDIA, walked us through how his team builds the company’s open models, the reasoning behind their architecture, and why NVIDIA open-sources so much of it.
Explore what's next in agentic operations: Introducing AI Week
For a full rundown of all the new features we announced (including a few not listed here), check out my AI Week recap blog post . Observability has traditionally been tacked on after your code hits production, but with agentic operations on the rise, that's no longer sustainable. Agents have dramati...
Postgres backups under the hood
With backups being such a vital part of keeping your data safe, how do they actually work?
A new allowlists design for Grafana Cloud IP addresses: What you need to know
If your network restricts inbound or outbound traffic, you likely maintain an allowlist of Grafana Cloud IP addresses so your systems and Grafana Cloud can talk to each other. Today we're introducing a new allowlists design : a single, structured API that replaces the collection of per-product lists...
A Beginner’s Guide to Clocks, Causality, and Ordering in Distributed Systems
Why does something as simple as reading the time become a hard problem for distributed systems?
How to monitor your Supabase projects: connect Grafana Cloud in one click
As AI agents accelerate software development and spin up applications at scale, visibility into what's happening behind the scenes, including query performance and database health, has never been more important. Gaining that level of insight requires observability that can keep pace. Supabase and Gr...
What's new in Postgres 19
`VACUUM` reclaims dead-tuple space but doesn't shrink a table. PostgreSQL 19 Beta 2 adds an in-core online rewrite with REPACK (CONCURRENTLY), and much more.

Best Practices for Building AI Agents That Work in Production
In this article, we try to explore the collective thinking into a smaller set of practices and explain the reasoning behind each one, rather than asking anyone to memorize a numbered list.
Cost attribution in Grafana Cloud: Manage spend across observability and testing workflows
Knowing what you're spending on observability is useful. Knowing which team, service, or project is driving that spend is what actually lets you act on that information. Cost attribution is a core part of how Grafana Cloud approaches cost management and optimization . It gives your organization a cl...
