Self-Hosted Linux cgroup v2 Administration: systemd-cgtop vs cgroup-tools vs libcgroup (2026)

Linux control groups (cgroups) are the kernel feature that makes modern containerization possible. They partition system resources — CPU, memory, disk I/O, and network bandwidth — into isolated groups, ensuring that one process cannot monopolize the entire system. With cgroup v2, the Linux kernel introduced a unified hierarchy, improved resource accounting, and better support for modern workloads like containers and virtual machines.

Self-Hosted cgroup Monitoring Tools: systemd-cgtop vs cgroup-tools vs libcgroup Guide

Control groups (cgroups) are the Linux kernel mechanism that enables resource isolation and accounting for containers, system services, and user sessions. Monitoring cgroup resource usage — CPU, memory, I/O, and network — is essential for container orchestration, capacity planning, and performance debugging. This guide compares three open-source tools for monitoring cgroup resource consumption: systemd-cgtop, cgroup-tools, and libcgroup utilities.
