🚀 Service Load Monitor

An enterprise-grade, “self-healing” system monitoring agent for Linux. This script goes beyond simple alerts by intelligently identifying high-load processes and automatically recovering services to ensure maximum uptime.

🌟 Features

  • Intelligent targeted recovery: Detects which specific service is causing a load spike and restarts only that service.
  • PC & Server awareness: Smart enough to protect desktop applications (browsers, editors) while managing backend services.
  • I/O Wait (D-State) detection: Identifies processes stuck in “Uninterruptible Sleep” (disk bottlenecks) which standard load monitors often miss.
  • Dynamic thresholds: Automatically calculates optimal load thresholds based on your CPU core count.
  • Web Dashboard: Real-time HTML status dashboard with auto-refresh.
  • Automatic firewall management: Detects and configures UFW or Firewalld automatically.
  • Backup & Restore: Safety-first approach with automated configuration backups.
  • Cloud Ready: Built-in awareness for AWS, Oracle Cloud, and Azure security environments.

🛠 Installation

You can install the Service Load Monitor with a single command:

Bash

wget -O service-load-monitor.sh https://github.com/waelisa/service-load-monitor/raw/refs/heads/main/service-load-monitor.sh && chmod +x service-load-monitor.sh && sudo ./service-load-monitor.sh

📋 Requirements

The script is designed to be universal and handles its own dependency installation. It supports:

  • Distros: Ubuntu, Debian, CentOS, RHEL, Fedora, Arch Linux.
  • System Manager: Systemd.
  • Dependencies: curl, awk, procps, net-tools (all auto-installed if missing).

🚀 Usage

Simply run the script with root privileges to access the management menu:

Bash

sudo ./service-load-monitor.sh

Menu Options:

  1. Install/Update Monitor: Set up the background service.
  2. Remove Monitor: Cleanly uninstall all files and services.
  3. Show Status: View real-time service health and logs.
  4. View Logs: Tail the monitor’s activity log.
  5. Backup/Restore: Manage your configuration safety nets.

🌐 Web Dashboard

Once installed, you can monitor your server health from any browser at: http://your-server-ip:8080

Note: If you are using a Cloud Provider (AWS/Oracle), ensure you open port 8080 in your Cloud Console Security Group.

✅ Enterprise Features

  • Auto-healing – Restarts only guilty services, not everything
  • I/O Wait detection – Catches disk bottlenecks (the silent killer)
  • Grand Unified Service Mapping – Maps ANY process to its systemd service
  • Multi-server support – Central dashboard for multiple servers

✅ Operations-Ready

  • Auto-starts on reboot – No manual intervention needed
  • Comprehensive logging – Everything logged for troubleshooting
  • Backup & restore – Full configuration backup before updates
  • Clean upgrades – Automatic cleanup of old versioned files

✅ Security Hardened

  • Sudo capability check – Verifies privileges before installation
  • Protected critical services – Never restarts sshd, dbus, etc.
  • Cloud-aware – Provides specific firewall instructions for AWS/Azure/GCP
  • No version numbers in files – Clean, simple paths

✅ Universal Compatibility

  • Works on Debian, Ubuntu, CentOS, RHEL, Fedora, Arch, Alpine
  • Uses awk for math (no bc dependency)
  • Multiple fallback methods for all commands
  • HTML-free cloud detection – No more messy output

📊 The Final Product:

bash

# One command to rule them all
sudo ./service-monitor.sh

# Simple service names
sudo systemctl status service-monitor.service
sudo systemctl status service-monitor-http.service
sudo systemctl status service-monitor-updater.service

# Clean logs
tail -f /var/log/service-monitor.log

# Web dashboard
http://your-server:8080/
