How CloudWatch Collects Linux Metrics | Interview question

In this video, I break down the AWS CloudWatch architecture for collecting Linux system metrics. Using /proc files (like /proc/meminfo) as an example, I explain how the CloudWatch Agent reads kernel‑level data, converts it into structured metrics, and uploads them to CloudWatch under a defined namespace. You’ll learn: How Linux exposes system stats through /proc (memory, CPU, disk, network). The role of the CloudWatch Agent in gathering and formatting metrics. How CloudWatch organizes metrics into namespaces and dimensions. Ways to use dashboards, alarms, and monitoring for better visibility. This guide is perfect for DevOps engineers, cloud architects, and sysadmins who want to understand how CloudWatch bridges low‑level Linux data with high‑level cloud monitoring. 🔑 Keywords: AWS CloudWatch, Linux monitoring, CloudWatch Agent, /proc/meminfo, system metrics, DevOps, cloud architecture, AWS monitoring, observability, infrastructure monitoring
