How to Use Linux Server cgroups v2 for Resource Control

In this episode of Linux Server Admin with Fexingo, Lucas and Luna dive into the practical side of cgroups v2 on Linux servers. They start with a real-world scenario: a runaway process eating CPU and memory, and show how cgroups v2 can tame it. Topics include the unified hierarchy, the difference between cgroups v1 and v2, and how to create and manage cgroups with systemd and the cgroupfs interface. They also cover how to read key files like cpu.max and memory.max, and how to monitor usage with tools like systemd-cgtop and cgroup events. With a mix of theory and hands-on examples, this episode helps you understand why cgroups v2 matters for modern server workloads and how to use it to prevent resource hogging. Perfect for sysadmins who want to move beyond the basics of resource management.
