Capture Server stats during the load test using python

          plt.figure(figsize=(10, 5))
          plt.plot(timestamps, cpu_percentages, label='CPU Usage (%)', color='blue')
          plt.plot(timestamps, memory_percentages, label='Memory Usage (%)', color='green')
          plt.xlabel('Time (seconds)')
          plt.ylabel('Usage (%)')
          plt.title('Server Stats During Load Test')
          plt.legend()
          plt.grid(True)
          plt.show()
      
      # Example usage: Capture server stats for 60 seconds with an interval of 1 second
      capture_server_stats(duration=60, interval=1)
    
  

psutil library is used to capture CPU and memory usage statistics.

capture_server_stats function captures CPU and memory usage at regular intervals for the specified duration.

The captured data is stored in lists (timestamps, cpu_percentages, memory_percentages).

The data is then plotted using matplotlib.
