🚀 Bashboard: Enterprise VPS Management System

Bashboard is not just another monitoring script; it is a Central Command Center engineered with strict SRE (Site Reliability Engineering) principles. Designed for SysAdmins and DevOps engineers, it provides zero-lag real-time monitoring, deep hardware-aware scanning, and a modular framework to manage LEMP/LAMP stacks without consuming your server's CPU.

✨ Enterprise-Grade Features

Under the hood, Bashboard replaces brittle traditional bash scripting with highly resilient, kernel-level mechanisms:

• 🛡️ Zero-Crash Policy (set -euo pipefail): Fully sanitized math operations and POSIX-compliant parsing prevent unexpected crashes even during kernel edge-cases.
• ⚡ Zero-Lag Polling: Heavy daemon discovery (like multiple PHP-FPM pools) is cached at startup. The live dashboard loop runs in < 5ms directly from /proc/ and /sys/.
• 🔐 Zero-Trust Security: Built-in defenses against Symlink attacks, strict umask 077 lock-file generation, and real-time SSH Hardening audits (PermitRootLogin analyzer).
• 🧠 Hardware-Aware Detection: Direct sysfs disk type reading (bypassing lsblk D-State hangs) to accurately detect NVMe/SSD vs HDD, even on complex cloud block devices.
• 🎨 Grafana-Style Thresholds: Dynamic, visually aligned UI that strictly shifts colors (White → Yellow → Red) based on DevOps critical limits (e.g., Swap triggers red at 60%).
• 🌍 Cross-Distro Mastery: Runs flawlessly on Ubuntu, Debian, CentOS, RHEL, AlmaLinux, Rocky, Arch, and SUSE via intelligent Package Manager routing and daemon aliasing.

📸 The Interface (Central Command Mode)

The UI is built with 100% Absolute Cursor Alignment, ensuring the terminal never distorts or flickers, even when variables change lengths.

⚙️ Directory Structure & Architecture

Bashboard uses a modular execution structure. The core loop handles the UI and safety, while heavy operations are outsourced to the scripts/ directory.

bashboard/
├── bashboard.sh            # The Core Engine & UI (Run this)
├── README.md               # Documentation
└── scripts/                # Action Modules (Modular Architecture)
    ├── install_lemp.sh     # Option 1
    ├── manage_wp.sh        # Option 2
    ├── site_summary.sh     # Option 3
    ├── backup_restore.sh   # Option 12
    └── ...                 # Extendable up to 99 modules

(Note: As of v0.8, the core foundation is 100% stable. Action scripts inside the scripts/ folder are actively being developed to reach version 1.0).

🛠️ Installation & Usage

1. Clone the repository:

git clone https://github.com/yourusername/bashboard.git
cd bashboard

2. Make the core script executable:

chmod +x bashboard.sh

3. Run as Root (Required for Kernel/Systemd interactions):

sudo ./bashboard.sh

---

🕹️ Integrated Live Tools (Non-Blocking)

Bashboard natively handles SIGINT (Ctrl+C) hooks to allow live tools to run securely without terminating the parent dashboard:

• [94] HTOP / TOP: Drops you into native process monitoring.
• [93] LIVE LOGS: Directly tails journalctl or /var/log/syslog securely.
• [92] NET-STAT: Live network port and TCP/UDP socket tracking via ss.

🛡️ Security Audit & Hardening Notes (For DevSecOps)

If you are auditing this code, note the following protections built-in:

• DBus Hang Prevention: Systemctl queries are safely encapsulated in a custom timeout wrapper (safe_cmd) to prevent dashboard freezes during systemd/dbus failures.
• Set-e Trap Survival: Sub-shell mathematical evaluations ($((...))) strictly strip non-numeric strings to prevent arithmetic expansions from triggering terminal exits.
• Interactive Prompts Blocked: Unattended upgrades (apt-get upgrade) use strict DEBIAN_FRONTEND=noninteractive and forced config overrides to prevent dpkg prompt hangs.

🤝 Contributing

Bashboard is an expanding framework. To create a new module:

1. Write a standard bash script.
2. Place it in the scripts/ directory.
3. Link it in the case "$opt" in block at the bottom of bashboard.sh.
