# CPU and RAM Usage Monitor

This utility monitors system resource usage in real-time. It uses `psutil` to fetch CPU percentage and memory statistics, displaying them in a continuously updating log format.

**Modules Used:**
*   `psutil`: To retrieve system utilization statistics.
*   `time`: To handle timestamps and intervals.

## Installation

```bash
pip install psutil
```

## The Code

Save this as `monitor.py`.

```python
import psutil
import time

def monitor_resources(interval=1):
    print(f"Monitoring System Resources (Interval: {interval}s)")
    print("Press Ctrl+C to stop.")
    print("-" * 55)
    # Header
    print(f"{'Time':<10} {'CPU (%)':<10} {'Memory (%)':<12} {'Memory (GB)':<10}")
    print("-" * 55)

    try:
        while True:
            # cpu_percent with interval blocks for that duration
            # This calculates the average CPU usage over the interval
            cpu = psutil.cpu_percent(interval=interval)
            
            memory = psutil.virtual_memory()
            mem_percent = memory.percent
            mem_used = memory.used / (1024 ** 3) # Convert Bytes to GB
            
            timestamp = time.strftime("%H:%M:%S")
            
            print(f"{timestamp:<10} {cpu:<10.1f} {mem_percent:<12.1f} {mem_used:<10.2f}")
            
    except KeyboardInterrupt:
        print("\nMonitoring stopped.")

if __name__ == "__main__":
    # You can adjust the interval (in seconds) here
    monitor_resources(interval=1)
```

## Usage

```bash
python monitor.py
```

The script will run indefinitely, printing a new line of stats every second, until you interrupt it with `Ctrl+C`.
