System Monitor Script

This script provides real-time monitoring of CPU, memory, and disk usage on a Unix-like system. It is designed to be easy to use and highly configurable.

Features

• Real-Time Monitoring: Displays CPU, memory, and disk usage every few seconds.
• Customizable Interval: Users can set the refresh interval.
• Multiple Disk Monitoring: Supports monitoring multiple disk mount points.
• Configuration File: Allows loading configuration from an external file.
• Graceful Exit: Handles SIGINT (Ctrl+C) and SIGTERM signals to exit gracefully.

Installation

1. Clone the Repository

   git clone https://github.com/elliotsecops/System-Monitor.git
   cd System-Monitor

2. Make the Script Executable

   chmod u+x system_monitor.sh

3. Install the Script

   ./install.sh

Usage

Basic Usage

To run the script with default settings:

system_monitor

Command-Line Options

• Set Interval: Use the -i or --interval option to set the refresh interval in seconds.

  system_monitor -i 10

• Add Disk Mount Points: Use the -d or --disk option to add disk mount points to monitor.

  system_monitor -d /mnt/data -d /mnt/backup

• Load Configuration File: Use the -c or --config option to load configuration from a file.

  system_monitor -c config.sh

• Display Help: Use the -h or --help option to display the help message.

  system_monitor -h

Configuration File

You can create a configuration file to set default values for interval and disk mount points. Here is an example config.sh:

INTERVAL=5
DISKS="/ /mnt/data /mnt/backup"  # Space-separated

Place this file in the same directory as the script or specify its path when running the script with the -c option.

Example

To monitor CPU, memory, and disk usage every 10 seconds, including /mnt/data and /mnt/backup mount points, using a configuration file:

1. Create a configuration file config.sh:

   INTERVAL=10
   DISKS="/mnt/data /mnt/backup"

2. Run the script with the configuration file:

   system_monitor -c config.sh

Troubleshooting

• Script Not Found: Ensure the script is executable and located in your current directory or specify the full path.
• Invalid Interval: The interval must be a positive integer. If you encounter an error, check the interval value.
• Disk Mount Points: Ensure the specified disk mount points exist and are accessible.
