A Practical Guide to Python Application Performance Monitoring (APM)

When your Python app starts slowing down, maybe queries are taking longer, memory keeps creeping up, or API calls are lagging—basic server metrics won’t tell you why. You need to see what’s happening inside the application itself. That’s the role of Application Performance Monitoring (APM). It gives you a breakdown of database queries, external API calls, memory usage, error rates, and more, so you can connect the dots between code and performance.

What is Database Monitoring

Database monitoring transforms from a reactive troubleshooting exercise into a proactive optimization strategy when you have the right tools and approaches in place. This blog shares practical ways to choose monitoring solutions, set up observability for different database platforms, and design workflows that scale in modern distributed systems.

Incident Response for DevOps, SREs, and IT Teams

That 3 AM alert is never fun. Your heart races as you try to figure out what broke this time, and how fast you can fix it. But with an incident response in place, that panic turns into a calm, step-by-step fix. It helps you handle everything, from a server crash to a security breach, in an organized way. In this guide, I’ll walk you through what exactly an incident response is, why you need it, its key components, and how to build one.

OpenTelemetry API vs SDK: Understanding the Architecture

When you're instrumenting applications with OpenTelemetry, you'll encounter two core components: the API and the SDK. The API defines what telemetry data looks like and how it is created, while the SDK handles how that data is processed and exported. Understanding this split helps you build more maintainable observability and avoid tight coupling between your business logic and telemetry infrastructure.

APM Logs: How to Get Started for Faster Debugging

When application performance monitoring detects a spike in latency or error rates, the immediate challenge is determining the underlying cause. APM logs address this by correlating performance metrics with the specific log events that occurred at the same time. Instead of switching between monitoring dashboards and manually searching through log files, APM log correlation consolidates both views.

A Detailed Guide to Azure Kubernetes Service Monitoring

Azure Kubernetes Service (AKS) continuously generates a high volume of telemetry, ranging from node-level CPU and memory usage to request latencies and error rates within individual pods and services. Without a structured monitoring strategy, this flood of metrics can easily become noise, leaving teams blind to early warning signs. Effective monitoring in AKS is about identifying the right signals, correlating them across layers, and acting before they impact application performance or cluster stability.

Your Apps Are Green. Your Infrastructure Is Dying.

Launch Week Day 3: Introducing Discover Infrastructure Your dashboard looks perfect. APIs responding in 80ms, background jobs processing smoothly, error rates at 0.02%. Everything's green. Then production breaks. "Why is checkout so slow?" "The payment service keeps timing out!" You run kubectl get pods and discover payment-service pods restarting every 3 minutes due to OOM kills. Then you check your database host—CPU at 98% because someone forgot the new ML training job runs there too.

Discover Infrastructure: Kubernetes & Hosts - Launch Week / Day 03

Stop debugging infrastructure issues across multiple dashboards. See how Last9's Discover Infrastructure monitors K8s pods and traditional hosts together—with resource analysis, pod-level debugging, and AI that correlates app problems to infrastructure root causes. One setup (K8s + host monitoring) → Complete infrastructure visibility that connects to your services and jobs. No more blind spots between application performance and underlying resources.

Frontline Reliability: Protecting User Journeys with SLOs with Shery Brauner (Razor, ex-Zalando)

What does it really take to move from firefighting incidents to building reliability at scale? In this episode of Humans of Reliability, Shery Brauner (Razor, ex-Zalando) shares her unique journey from frontend and backend engineering to leading site reliability practices. She explains why protecting the user journey is the key to effective incident management, how SLOs cut through noisy alerts, and why observability must come first.
