cgroup

What This Skill Does

The cgroup skill for OpenClaw is a specialized technical reference and sysops utility designed to assist systems engineers, DevOps professionals, and platform administrators in managing Linux Control Groups (cgroups). This skill encapsulates best practices, configuration patterns, and troubleshooting heuristics, allowing you to interface with complex resource management tasks through an intuitive command-line structure. Whether you are working with cgroup v1 or v2, this tool provides standardized paths for identifying resource constraints, CPU and memory isolation strategies, and deep-dive diagnostic procedures. By acting as an internal documentation engine, it reduces the cognitive load of memorizing syntax and path structures across different kernel versions, ensuring that your system resource orchestration remains consistent and compliant with industry standards.

Installation

To integrate this utility into your OpenClaw environment, execute the following command in your terminal. Ensure that your OpenClaw CLI is updated to the latest version before running the installation to avoid dependency conflicts:

clawhub install openclaw/skills/skills/bytesagain1/cgroup

Once installed, you can verify availability by running the scripts/script.sh help command to view all available modules and command options. No additional dependencies are required, as the skill operates via local shell scripts.

Use Cases

This skill is specifically designed for high-stakes sysops environments. You should utilize it during the following scenarios:

• Resource Bottlenecks: When a container or process is consuming unexpected CPU or memory, use the debugging command to identify cgroup-related throttling issues.
• Deployment Planning: Use the patterns command to apply industry-standard cgroup hierarchy designs before rolling out new microservices.
• Kernel Migrations: Use the migration module to understand the syntactic and behavioral differences when moving from cgroup v1 (legacy) to cgroup v2 (Unified Hierarchy).
• Compliance & Security: Consult the security documentation to implement proper isolation and limit resource-based denial-of-service (DoS) vectors on multi-tenant hosts.

Example Prompts

1. "OpenClaw, please run the cgroup debugging sequence to help me diagnose why my Docker container is being throttled by the CPU quota."
2. "Can you provide the recommended patterns for memory limit configuration to prevent OOM kills on our production nodes?"
3. "Show me the cheatsheet for the most common cgroup v2 commands I need for managing systemd slice constraints."

Tips & Limitations

• Permissions: Note that many cgroup administrative actions require root or sudo privileges. The skill provides the logic, but you must ensure your OpenClaw environment has the necessary escalation rights to modify kernel parameters.
• Version Sensitivity: Always check the version command output against your kernel version. Some features are specific to kernel 4.15+ (cgroup v2 support).
• Non-Destructive Nature: The primary commands provided in this skill are for reference and diagnostic guidance. While it can help you build commands, be cautious when applying high-level restrictions to critical system services.
