System Resource Monitor

A Python script that continuously monitors and logs system resources and battery status.

Features

• Monitors CPU, memory, and disk usage
• Tracks processes consuming high CPU and memory
• Logs battery status and estimated remaining time when on battery power
• Creates detailed logs with timestamps

Requirements

• Python 3.6+
• psutil library

Installation

1. Install the required dependency:

pip install psutil

2. Make the script executable (optional):

chmod +x system_monitor.py

Usage

Run the script:

python3 system_monitor.py

The script will:

• Create a logs directory if it doesn't exist
• Log information to both the console and logs/system_monitor.log
• Run continuously until interrupted with Ctrl+C

Configuration

You can modify these variables at the top of the script:

• INTERVAL: Time between checks (default: 60 seconds)
• CPU_THRESHOLD: Minimum CPU percentage to report (default: 10%)
• MEMORY_THRESHOLD: Minimum memory percentage to report (default: 5%)
• TOP_PROCESSES: Number of top processes to log (default: 5)
