remote-system-maintenance

What problem does it solve?

This skill provides structured guidance for diagnosing and maintaining remote Linux systems via SSH, enabling proactive health checks and reliable cleanup operations.

Core Features & Use Cases

• Three-phase workflow: Initial diagnostics, log review, and package assessment to systematically identify issues and opportunities on remote servers.
• Ubuntu/Debian focus: Tailored steps for common distributions, including apt-based upgrades, autoremove, cache cleanup, and journal pruning.
• Use Case: You manage several Ubuntu servers and need a repeatable protocol to baseline performance, identify upgrades, and reclaim disk space with documented results.

Quick Start

• Connect to the remote Linux server: ssh user@host
• Open a maintenance tmux session: tmux new -s remote-maintenance
• Phase 1 (Diagnostics): hostname; uname -a; df -h; free -m; top -b -n1 | head -n 20; ps aux --sort=-%mem | head -n 5
• Phase 2 (Logs & Services): journalctl -p err -n 100; systemctl list-units --type=service --state=running
• Phase 3 (Cleanup & Maintenance): sudo apt list --upgradable; sudo apt autoremove -y; sudo apt clean; sudo journalctl --vacuum-time=7d; snap list --all | awk '/disabled/{print $1, $3}'; sudo snap remove <package> --revision=<rev>; ls -ld /tmp /var/tmp
