I've prepared a guide to understand when my containers slow down. In this post, I'll explain step-by-step how I monitor the performance of Docker containers on my own VPS. Sometimes a simple configuration change, and other times insufficient underlying system resources, can significantly impact performance. Systematically managing this process is critical for early detection and resolution of potential issues. Monitoring the performance of applications running on my own servers is particularly important to me. While Docker's isolation and portability are excellent, it's crucial to properly manage and monitor the underlying system resources these containers rely on. In this guide, I'll share how I manage this process and resolve typical issues I encounter. Fundamentals of Container Performance Monitoring There can be many reasons why a Docker container slows down. These include factors such as CPU usage, memory consumption, I/O bottlenecks, or network latencies.…
