Connect to any Linux VPS with your root credentials and get an instant, full-colour report on what's going wrong. vitals-vps acts as an automated system administrator, identifying CPU spikes, active brute-force attacks, memory pressure, disk exhaustion, and zombie processes—and gives you the exact commands to fix them.

✅ 100% Safe & Read-Only: Every command is strictly filtered through a safety blocklist. No files are created, modified, or deleted. No services are restarted.

🚀 Installation

Install globally via pip:

pip install vitals-vps

(Requires Python 3.8+, paramiko, and rich)

💻 Usage

You can use vitals-vps straight from your terminal or programmatically via Python.

Terminal CLI

# Prompt for password (recommended)
vitals 192.168.1.10 --ask-pass

# Use an SSH key instead of a password
vitals 192.168.1.10 --key ~/.ssh/id_rsa

# Non-standard port or user
vitals 192.168.1.10 --port 2222 --user ubuntu --ask-pass

# Verbose mode: Also show raw process lists, log excerpts, and port tables
vitals 192.168.1.10 --ask-pass --verbose

# JSON output: pipe structured findings into CI/alerting pipelines
vitals 192.168.1.10 --ask-pass --output json

Python API (Jupyter / Scripts / Google Colab)

Perfect for integrating into automated monitoring dashboards or running from Jupyter Notebooks.

import vitals

# Print the full styled report to your screen
vitals.info("192.168.1.10", password="mypassword")

# Use key-based authentication
vitals.info("192.168.1.10", user="ubuntu", key="~/.ssh/id_rsa")

# Silent execution: Returns a list of Finding objects for automation
findings = vitals.scan("192.168.1.10", password="mypassword")

critical_issues = [f for f in findings if f.severity.value == "critical"]
for issue in critical_issues:
    print(f"Alert: {issue.title}")

── CPU ──────────────────────────────────────────
🔴 Extreme load average: 8.4 on 4 core(s)
  📋 1-min load=8.4, 5-min=6.2, 15-min=4.1. With 4 cores,
     the system has ~2x more runnable work than it can handle.
  💡 What to do: Identify the runaway process(es)…
  📌 Commands:
     ps aux --sort=-%cpu | head -15
     top -b -n1 | head -20

── Security ─────────────────────────────────────
🔴 Active brute-force attack: 47,312 SSH login failures
  📋 47,312 failed SSH login attempts found in auth log.
  💡 What to do:
     1. Install fail2ban immediately to auto-ban attackers.
     2. Change SSH to a non-standard port (e.g. 2222).
     3. Disable password login — use SSH keys only.
  📌 Commands:
     apt install fail2ban -y
     systemctl enable --now fail2ban

🔒 Safety Guarantees

• Hardware Level Guard: Every SSH command runs through a rigorous blocklist filter. If a command string contains anything resembling a write, delete, kill, or install operation, it immediately raises a ValueError before sending it to your server.
• No Artifacts Left Behind: No temporary data is written to disk. The tool runs entirely in memory, prints the results, and cleanly closes the SSH connection.
• Secure Key Management: The SSH client leverages AutoAddPolicy for seamless connections, but strictly logs host keys to prevent man-in-the-middle attacks.

🗺️ Roadmap

• --output json flag for piping directly into CI/CD or alerting pipelines
• --watch mode: re-scan every N seconds for live monitoring
• HTML report export for client delivery
• Docker container support (scan via docker exec)
• Baseline comparison mode: diff current findings against a historical baseline
