python
import psutil

# Get CPU utilization percentage
cpu_percent = psutil.cpu_percent(interval=1)

# Get memory usage
memory_usage = psutil.virtual_memory().percent

# Get disk usage
disk_usage = psutil.disk_usage('/').percent

# Get network statistics
network_stats = psutil.net_io_counters()

print(f"CPU Percent: {cpu_percent}%")
print(f"Memory Usage: {memory_usage}%")
print(f"Disk Usage: {disk_usage}%")
print(f"Network Stats: {network_stats}")

This code imports the `psutil` library, which provides an interface for retrieving system information. It retrieves the CPU utilization percentage, memory usage percentage, disk usage percentage, and network statistics. You can customize and extend this code as per your requirements.

Please note that this code is just a basic example to get you started. Depending on your specific needs, you may need to explore additional functionalities provided by the `psutil` library or consider using other tools or libraries to gather more specific performance metrics.
