System Monitoring and Process Management Script

Overview

This Bash script is designed to monitor system resources, manage processes interactively, and provide real-time monitoring capabilities. It includes functions for logging activities, managing processes, displaying system statistics, and performing operations such as process termination and searching/filtering processes. The script utilizes configurations specified in Task_B_Options.conf for thresholds and intervals.

Scripts

Main Script (Task_B.sh)

  • Monitors system resources (CPU and memory usage).
  • Loads configurations from Task_B_Options.conf for thresholds and intervals.
  • Includes functions from Functions_Task_B.sh for logging activities, managing processes, and interacting with the user.
  • Provides an interactive menu for operations including listing processes, displaying process information, terminating processes, viewing system statistics, real-time monitoring, and searching/filtering processes.

Functions

Functions

  • log_activity: Logs activities with timestamps to Task_B.log.
  • list_processes: Lists running processes sorted by CPU and memory usage.
  • process_info: Provides detailed information about a specified process.
  • kill_process: Terminates a specified process by its PID.
  • process_statistics: Displays overall system process statistics including total processes, CPU load, and memory usage.
  • real_time_monitoring: Provides real-time monitoring of running processes.
  • search_processes: Allows searching and filtering of processes based on user-defined criteria.
  • check_alerts: Monitors processes for high CPU and memory usage alerts, printing and logging detected alerts.
  • cleanup: Terminates background processes and exits the script cleanly.
  • interactive_mode: Provides an interactive menu for the user to select and execute various operations related to process management and system monitoring.

Prerequisites

  • Ensure Bash is installed on your system.
  • Create and configure Task_B_Options.conf for custom settings such as thresholds and intervals.
  • Place Functions_Task_B.sh in the same directory as Task_B.sh to ensure all functions are accessible.

Usage

  1. Clone the repository to your local machine:

    git clone <https://github.com/OmarElmelegy/Process_Monitor.git>
cd <repository-directory>

  2. Make the script executable:

    chmod +x Task_B.sh

  3. Run the script:

    ./Task_B.sh

  4. Follow the interactive menu to perform operations related to process management and system monitoring.

Examples

Example 1: Starting the Script

./Task_B.sh

This command starts the interactive menu for the System Monitoring and Process Management script, allowing you to monitor and manage system processes interactively.

Example 2: Custom Configuration

Edit Task_B_Options.conf to customize thresholds and intervals:

# Example Task_B_Options.conf
UPDATE_INTERVAL=15
CPU_THRESHOLD=85
MEMORY_THRESHOLD=90
ALERTS_INTERVAL=2

Trapping Exit Signals and Cleaning Up

The script traps exit signals (SIGINT and SIGTERM) to ensure proper cleanup of background processes:

# Trap [ctrl+c] or general termination of the script to trigger cleanup
trap cleanup SIGINT SIGTERM

# Cleanup function to terminate background processes
cleanup() {
  if [[ $ALERTS_PID -ne 0 ]]; then
    kill $ALERTS_PID
  fi
  exit 0
}

Error Handling

  • If Task_B_Options.conf is missing or incorrectly configured, default settings will be used.
  • Ensure Functions_Task_B.sh is present in the same directory as Task_B.sh to avoid errors related to missing functions.

Notes

  • The script provides comprehensive functionalities for managing processes and monitoring system resources interactively.
  • Properly terminate the script using the interactive menu option to ensure cleanup of background processes (cleanup function).
