How to Use the System Performance Monitor Script (Simulated)

1. What This Script Does

• This script simulates monitoring your computer’s CPU and memory usage.
• It does not use real hardware data unless you install the psutil package; instead, it generates random but realistic values.
• It’s safe to run anywhere, including Google Colab or Jupyter Notebook.

2. Requirements

• No installation needed if you use Google Colab or Jupyter Notebook.
• If you want to monitor real system data, you must install the psutil library in your environment (see “Advanced: Real Monitoring” below).

3. Running the Script

Option A: Run in Google Colab (Recommended for Beginners)

1. Click this link to open the notebook:
   Open in Google Colab
2. In Colab, click the “Run All” button (or run each cell in order using the play buttons on the left).
3. You will see output lines showing simulated CPU and memory usage every 5 seconds.
4. To stop the script, click the stop button (“interrupt execution”/square button) at the top, or press Ctrl+C if running in a local terminal.

Option B: Run in Jupyter Notebook (Locally)

1. Download the notebook file from GitHub.
2. Launch Jupyter Notebook on your computer and open the downloaded file.
3. Run all the code cells.
4. Watch the output update every 5 seconds.
5. To stop, click “Interrupt Kernel” or press Ctrl+C in the terminal.

4. What You Will See

• Messages like:

  2025-05-23 07:01:34 - INFO - CPU Usage: 21.1% | Memory Usage: 23.2% (1901.58 MB Used / 8192.00 MB Total)
  

• Warnings that the data is simulated unless psutil is installed.

5. Advanced: Use Real Hardware Data (Optional)

If you want to see your actual system performance:

1. Install the psutil library:
   • In Colab/Jupyter:
     Run !pip install psutil in a new code cell.
   • Or, in your terminal:
     Run pip install psutil
2. Open the notebook file.
3. Uncomment the line import psutil at the top.
4. In the log_system_performance() function, comment out the simulated data lines:

   # cpu_usage = get_simulated_cpu_percent()
   # memory_info = get_simulated_virtual_memory()

   And uncomment the real data lines:

   cpu_usage = psutil.cpu_percent(interval=None)
   memory_info = psutil.virtual_memory()

5. Run the notebook again. Now it will display real CPU and memory usage.

6. Stopping the Script

• The script runs in a loop, logging data every 5 seconds.
• To stop it:
  • In Colab/Jupyter, press the stop or “interrupt” button.
  • In a terminal, press Ctrl+C.

---

7. Troubleshooting

• If you see warnings about psutil not being available, it’s normal for simulated mode.
• If you want to use real data, be sure to install psutil and follow the “Advanced” steps above.
