A checkout request leaves the browser and touches seven services before anything comes back. Seven dashboards light up. Every one of them reports a healthy number for its own service, and every one of them is telling the truth about a different slice of the work. Nobody measured the request. That gap is what pushed tracing in beside metrics and logs as a core signal of observability. In this blog, you will: By the end you will open a trace and say where the time went.

Why does a checkout or login take several seconds when CPU and memory look normal on every server? In microservices, one click can travel through a long chain of components before the user sees a response. Any one of them can hold the request up, and server graphs won't tell you which. Logs show what each service recorded. Metrics give you averages. What's missing is the path one request took and the place it lost time, and Jaeger tracing records exactly that.

‍‍Gartner expects more than 40% of agentic AI projects to be canceled by the end of 2027. Its reasons read like a budget memo: escalating costs, unclear business value, and inadequate risk controls. For revenue leaders, the stakes run in both directions. MGI Research estimates that at least 3% to 5% of revenue leaks between contract and cash, through missed renewals, unbilled usage, and pricing errors. Agents are well suited to close those gaps.

If you've spent any time in an engineering Slack lately, you've probably noticed that AI comes up in just about every conversation. Someone's using an assistant to scaffold a new service. Someone else has an agent triaging alerts overnight. And at least one person is asking whether all of this means the team can finally skip the "platform stuff.".

Learn how Harness MCP OAuth proxy mode enables enterprise developers to use their own identity provider without static tokens or shared credentials. OAuth proxy mode lets enterprises run Harness MCP behind their own identity provider, with no static tokens anywhere in the chain. Coding agents write the change. Harness agents take it through production, running the builds, tests, scans, and deployments that follow, with policy enforced on every action.

Discover how php2shell vulnerabilities expose PHP servers to remote code execution and how Harness virtual patching protects endpoints while you deploy fixes. On October 21, 2026, the PHP project rushed out emergency patches for two critical flaws nicknamed php2shell (CVE-2026-109618 and CVE-2026-109619, both rated 9.2 out of 10). This isn't a bug in some plugin or a server someone set up wrong. It's in PHP itself, in the way the language has handled errors since 2012.

You're investigating checkout errors when someone asks who's coordinating the incident. Support needs an update, and another responder is looking for the runbook. You stop what you're doing to get everyone pointed in the same direction. They're all reasonable requests, but each one takes your attention away from understanding the problem. Yes, your team has a process for handling incidents, but carrying it out is another job for someone who's already busy.

Software teams are taking on more work than ever. Developers are juggling more branches, coding agents are keeping CI busy through the weekend, and builds are passing more often and finishing faster. But is all that extra activity helping teams ship faster? Today we released the 2026 State of Software Delivery Q3 Pulse report, the latest in our quarterly series tracking how software teams are adapting to AI-driven development.

The rise of large-language models (LLMs) that can understand and create text, and reason about problems has opened the door for software agents that use the reasoning power of LLMs to interact with the wider world and solve problems. At Kubex, our bread and butter is compute and GPU resource optimization, so it’s natural for us to ask how agents could help our customers more effectively optimize their resources.

Last updated: October 21, 2026. We'll update this article as PHP and Linux distributions publish new information. PHP2Shell is the nickname of two critical vulnerabilities in PHP that let an attacker run code on a web server without logging in. PHP released the fixes on October 21, 2026, and IT and security teams now need to know which of their servers and computers run a vulnerable PHP version, so they can patch those first.
