Dash0 vs Grafana Labs

Founders Use OpenAI Codex and Vercel to Build Startups

The article profiles three startup founders—Vincent, Amerigo, and Jolina—participating in the 'Gründerszene sucht die Supergründer' fellowship program in Berlin. They leverage AI tools to build their consumer startups without deep coding expertise. OpenAI's Codex is used for coding assistance, code review, and automated testing, while Vercel handles deployment and preview testing via private links. Dash0 is planned for future monitoring of AI application performance, latency, and costs, though not yet fully integrated. The ten-week program, supported by partners including OpenAI, Vercel, Dash0, and DHL, guides fellows from idea to product. All resulting products are owned by Axel Springer.

• Three founders use OpenAI's Codex for coding, review, and testing without deep coding skills.
• Vercel is used for deploying web applications and creating private preview links for testing.
• Dash0 is planned for monitoring AI application performance and costs, but is not yet in daily use.

Dash0 Acquires Polar Signals to Enhance AI Observability

Dash0, a German-American observability software startup, has acquired Berlin-based Polar Signals, a company specializing in continuous profiling. The acquisition aims to integrate deeper code-level performance analysis into Dash0's platform and enable AI agents to autonomously monitor and optimize software. Dash0 plans to use Polar Signals' Great Lakes storage engine, replacing ClickHouse in its SignalStore infrastructure. Founded in 2023 by Mirko Novakovic, Dash0 recently raised $110 million in Series B funding at a $1 billion valuation, achieving unicorn status. It serves over 750 customers, including Zalando, Taco Bell, and The Telegraph. The deal highlights Dash0's shift from traditional monitoring to AI-driven self-optimizing software, where AI agents can identify and fix performance issues before human intervention.

• Dash0 acquired Polar Signals, a Berlin-based continuous profiling startup.
• Dash0 will integrate Polar Signals' profiling data into its AI agent 'Agent0'.
• Polar Signals' Great Lakes storage engine will replace ClickHouse in Dash0's SignalStore.

Dash0 Acquires Berlin Startup Polar Signals to Strengthen AI Platform

German-American observability startup Dash0 has acquired Berlin-based Polar Signals, a startup specializing in continuous profiling. The companies announced the deal on Monday. Dash0 plans to integrate Polar Signals' profiling technology into its platform, allowing developers to trace CPU and memory consumption down to specific code lines. It is also building agentic features, including Agent0 and AutoTune, which enable AI agents to detect inefficiencies and prepare optimization pull requests. As part of the transaction, Dash0 will adopt Polar Signals' storage engine Great Lakes as the basis of its SignalStore, replacing ClickHouse. Dash0 was founded in 2023 by Mirko Novakovic, who previously built Instana and sold it to IBM in 2020. The company recently raised $110 million in Series B funding at a $1 billion valuation, achieving unicorn status. It counts more than 750 customers, including Zalando, Taco Bell, and The Telegraph.

• Dash0 acquired Berlin-based startup Polar Signals, announced around August 20, 2026.
• Polar Signals specializes in continuous profiling, which helps developers trace CPU and memory usage to specific code lines.
• Dash0 will use Polar Signals' Great Lakes storage engine as the basis for SignalStore, replacing ClickHouse.

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.
