CloudWatch Insights isn’t just another AWS feature — it’s like having X-ray vision into your cloud. And Arjun, our curious cloud explorer, was about to find out why.
He could already build apps, spin up servers, and even use EventBridge like a pro. But something still bugged him…
“I can deploy things, but how do I see what’s going on inside them?”
That’s when CloudWatch whispered in his ear:
“Use my Insights.”
🧱 1. CloudWatch Container Insights – Monitor Kubernetes & ECS
Arjun’s team was using containers. Some were on ECS, others on EKS, and a few on plain old EC2 with Kubernetes. And each time something slowed down, they had to jump into logs manually.
“There has to be a better way!” Arjun muttered.
Boom 💥 — enter CloudWatch Container Insights.
It’s like giving CloudWatch X-ray vision into your containers.
- It collects logs and metrics from ECS, EKS, and Kubernetes.
- It automatically creates dashboards so you see CPU, memory, disk I/O, and network metrics.
- Behind the scenes, it runs a CloudWatch Agent inside a container to discover what’s running.
Use case: Want to monitor hundreds of microservices without building dashboards yourself? This is your answer.
⚡ 2. CloudWatch Lambda Insights – Debug Serverless Like a Pro
Next, Arjun moved his monolith into serverless Lambda functions. But now, things like cold starts and memory limitsstarted haunting him.
That’s where Lambda Insights came to the rescue.
It’s like a real-time health monitor for your serverless functions.
- It tracks CPU, memory, duration, cold starts, and more.
- It runs as a Lambda Layer next to your function.
- And best of all — it creates a dedicated dashboard just for Lambdas.
Use case: If your Lambdas are slow, failing, or inconsistent — this will show you why.
🧠 3. CloudWatch Contributor Insights – Find Top Traffic Sources
One day, during a network check, Arjun noticed something strange.
“Why is the internet so slow? Who’s using all the bandwidth?” he wondered.
To find out, he used CloudWatch Contributor Insights — a tool that helps you spot the “top users” inside your system.
- It looks at your logs (like VPC Flow Logs or DNS Logs).
- It tells you who’s doing the most activity — like top IP addresses, top users, or top URLs.
- Example: It can show the top 10 IPs using the most network traffic in your VPC.
This helped Arjun quickly find a misbehaving script sending too much traffic — and fix it right away.
In short: Contributor Insights helps you see who’s causing the most load so you can fix issues fast.
🚨 4. CloudWatch Application Insights – End-to-End Monitoring
Finally, Arjun needed a bird’s eye view of his full application stack — EC2, RDS, ELB, Lambda, and more.
But building custom dashboards was time-consuming.
Solution?
Application Insights – the brainy assistant that:
- Automatically detects issues using Machine Learning (via SageMaker).
- Builds dashboards showing root cause of failures.
- Connects with EventBridge and SSM OpsCenter to send alerts and start automated fixes.
Use case: Want to reduce MTTR (mean time to repair) and catch hidden problems across your app stack? Application Insights does it for you.
🧠 TL;DR on CloudWatch Insights – Arjun’s Handy Guide

| Application Insights | Auto-detect app issues and show dashboards | End-to-end app troubleshooting |
FAQ
Q1. What are CloudWatch Insights in AWS?
CloudWatch Insights are advanced features (Container, Lambda, Contributor, Application) that help monitor, troubleshoot, and optimize AWS workloads.
Q2. How does CloudWatch Container Insights work?
It collects logs and metrics from ECS, EKS, and Kubernetes, giving visibility into CPU, memory, and network usage with ready-made dashboards.
Q3. What’s the difference between CloudWatch Lambda Insights and Application Insights?
Lambda Insights focuses on individual serverless functions, while Application Insights monitors your entire application stack across multiple services.
Q4. Why should I use CloudWatch Contributor Insights?
Contributor Insights shows the “top contributors” to traffic or errors, helping you pinpoint the sources of performance issues quickly.
Q5. Is CloudWatch Insights beginner-friendly?
Yes. CloudWatch Insights automatically builds dashboards, making it easier for beginners to visualize performance without manual setup.
