🖥️ server-health

Check server health — CPU, RAM, disk, uptime, top processes — via SSH. No agent software needed on the server.

🦞 Pixeyo CuratedRequires: ssh✓ Read source below

Monitor any remote server's health over SSH. No agent or daemon needed on the server side — uses standard Linux commands.

When to Use

Use this skill when the user asks about server health, server status, CPU usage, memory usage, disk space, uptime, or running processes on a remote machine.

How to Check

Run the following commands via SSH. Replace TARGET with the user's server (e.g. user@hostname or an SSH config alias).

Quick health snapshot (one command)

ssh TARGET 'echo "=== UPTIME ===" && uptime && echo "=== CPU ===" && top -bn1 | head -5 && echo "=== MEMORY ===" && free -h && echo "=== DISK ===" && df -h --total 2>/dev/null || df -h && echo "=== TOP 5 PROCESSES ===" && ps aux --sort=-%mem | head -6'

Individual checks

Uptime: ssh TARGET uptime
CPU load: ssh TARGET "top -bn1 | head -5"
Memory: ssh TARGET "free -h"
Disk: ssh TARGET "df -h"
Top processes by memory: ssh TARGET "ps aux --sort=-%mem | head -10"
Top processes by CPU: ssh TARGET "ps aux --sort=-%cpu | head -10"
Docker containers (if applicable): ssh TARGET "docker ps --format 'table {{.Names}}\\t{{.Status}}\\t{{.Ports}}' 2>/dev/null || echo 'Docker not running'"
System logs (last errors): ssh TARGET "journalctl -p err --no-pager -n 20 2>/dev/null || tail -20 /var/log/syslog"

Response Format

Present results in a clean summary:

🟢 if values are healthy (CPU < 80%, RAM < 85%, disk < 90%)
🟡 if approaching limits (CPU 80-95%, RAM 85-95%, disk 90-95%)
🔴 if critical (CPU > 95%, RAM > 95%, disk > 95%)

Example:

Server: myserver (192.168.1.10)
⏱ Uptime: 43 days
🟢 CPU: 12% (load avg: 0.45, 0.32, 0.28)
🟢 RAM: 6.2G / 16G (39%)
🟡 Disk: 85% used (42G / 50G)
🟢 Top process: node (420MB)

Rules

Always confirm the server hostname/alias with the user before connecting.
Never store or log SSH credentials.
If SSH fails, suggest the user check their SSH config or key setup.
Do not run any write/modify commands — this skill is read-only monitoring.
