Tempo 3.1 release: new features for Kafka, TraceQL metrics updates, trace redaction, and more

Grafana Labs blog features a new post on Tempo 3.1 release with new features for Kafka, TraceQL metrics updates, trace redaction, and more.

Observability Stack: Prometheus, Node Exporter, Grafana

A technical how-to explaining the three-piece observability stack: Prometheus (time-series database that scrapes metrics), Node Exporter (exposes OS-level metrics at a /metrics HTTP endpoint), and Grafana (visualizes Prometheus data as dashboards). The article describes the pull-based model Prometheus uses, the role of Node Exporter as a translator of OS stats, how Grafana queries Prometheus, default ports (Prometheus 9090, Node Exporter 9100, Grafana 3000), basic install commands, a sample prometheus.yml with scrape_interval and job_name, and next steps such as adding scrape targets, writing PromQL queries, and adding Alertmanager for notifications.

• Prometheus is a time-series database and monitoring system that scrapes metrics from HTTP endpoints and exposes its own metrics on port 9090.
• Node Exporter exposes hardware and OS-level metrics at a /metrics endpoint (default port 9100) and is typically installed one-per-machine.
• Grafana queries Prometheus (e.g., via PromQL) to render dashboards and runs by default on port 3000; it stores no metrics itself.

Building an Internal Developer Platform on Azure AKS

This technical article explains how to create an Internal Developer Platform (IDP) using Azure Kubernetes Service (AKS). It outlines core components including AKS as the managed Kubernetes backbone, a service mesh (e.g., Istio or Linkerd) for microservice communication, CI/CD pipelines (Azure DevOps, GitHub Actions, Jenkins) for automated build and deployment, monitoring and logging tools (Azure Monitor, Prometheus, Grafana, Azure Log Analytics), and security/compliance controls (RBAC, Pod Security Policies, Azure Policy, Azure Security Center). The piece describes an example developer workflow from code push to production and summarizes benefits such as increased efficiency, scalability, security, and consistency.

• An Internal Developer Platform (IDP) is a set of tools, processes, and automations that simplifies development, testing, and deployment for developers.
• Azure Kubernetes Service (AKS) is presented as the central managed Kubernetes environment where containerized applications run.
• Service meshes such as Istio or Linkerd are recommended to manage microservice communication, including load balancing, traffic management, and security policies.

AI Agent Frameworks Have a Critical Engineering Flaw

The author argues that the current enthusiasm for AI "agents" and hot frameworks distracts from the real engineering challenges of production systems. They define a true agent as a system with an objective that decides next actions, handles failure, and knows when it is done. In production, most agent deployments are narrow, purpose-built pipelines (e.g., support triage, document extraction, code review). Teams that succeed focus on tool design, failure handling, and observability rather than swapping models. The author highlights a persistent retrieval problem in RAG pipelines—incorrect chunking and metadata cause context loss and hallucinations—and recommends architectural patterns (plan-then-execute, separate retrieval from reasoning, explicit handoffs) and better data representations over framework chasing.

• Author defines an 'agent' as a system with an objective that decides what to do next, handles failure, and knows when it is done.
• Most production AI agent deployments are narrow and purpose-built (examples: customer support triage, document extraction, code review).
• Successful teams prioritize tool design, failure handling, and observability over only upgrading model versions.

Workplace AI Needs a 'Chief of Staff' Control Plane

The article argues that businesses deploying multiple AI agents face 'agent sprawl'—fragmented context, uncontrolled side effects, and human operator fatigue—and proposes a split architecture: a central control plane (an "AI Chief of Staff") that handles governance, state, routing, human-in-the-loop approvals, and executive synthesis, while domain-specific workers perform execution. The author open-sourced a reference foundation called OpenClaw Control Plane (a TypeScript monorepo) on GitHub and recommends standardizing interfaces using the Model Context Protocol (MCP) and a workflow-neutral runtime, with deployment examples using Railway. The repo is presented as an M1 foundation with future plans for worker specs, MCP tool bridges, and operator dashboards.

• The article frames 'agent sprawl' as a common problem where siloed AI tools operate without centralized governance.
• It proposes a control plane (an "AI Chief of Staff") responsible for intake triage & routing, state & cross-functional memory, human-in-the-loop governance, and executive synthesis.
