What is APM Tracing?

Sep 3, 2025 By Faiz Shaikh In Last9
APM tracing records the complete execution path of a request as it travels through your system, including database queries, external API calls, cache lookups, message queue events, and inter-service requests. Each step is captured with precise start and end timestamps, duration, and context such as service name, operation name, and relevant attributes. This lets you pinpoint where latency or errors originate without piecing together metrics and logs manually.

A Single Hub for Telemetry: OpenTelemetry Gateway

Sep 1, 2025 By Anjali Udasi In Last9
The OpenTelemetry Gateway (OTel Gateway) is a centralized service that collects, processes, and routes telemetry data—metrics, traces, and logs—across your infrastructure. In a typical setup, each service pushes telemetry directly to an observability backend. While this approach works well for small environments, it becomes increasingly difficult to manage as systems grow.

A Practical Guide to Python Application Performance Monitoring (APM)

Aug 29, 2025 By Anjali Udasi In Last9
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.

Incident Response for DevOps, SREs, and IT Teams

Aug 25, 2025 By Sreekar In Spike
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

Aug 25, 2025 By Anjali Udasi In Last9
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

Aug 21, 2025 By Anjali Udasi In Last9
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

Aug 20, 2025 By Faiz Shaikh In Last9
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.

Aug 20, 2025 By Nishant Modak In Last9
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.
