How Can I Easily Retrieve System Status (CPU, RAM, etc.) in Python?

Retrieving System Status in Python: CPU, RAM, and Beyond

In Python, there are several ways to obtain real-time system status information, including CPU usage, RAM consumption, and disk space utilization. While platform-specific approaches using tools like os.popen and MEMORYSTATUS can be effective, these methods lack cross-platform compatibility and may require extensive coding efforts.

Fortunately, there is a well-supported and versatile solution for this task: the psutil library.

Introducing psutil

psutil is a comprehensive Python module designed to provide easy access to system utilization information. It supports a wide range of operating systems, including Linux, Windows, macOS, and Solaris, ensuring cross-platform consistency. The library is actively maintained and offers a rich set of functions for monitoring various system metrics.

Getting CPU and RAM Usage with psutil

Using psutil to retrieve CPU and RAM usage is straightforward:

import psutil

# Get CPU usage as a float value (0-100%)
cpu_usage = psutil.cpu_percent()

# Get RAM usage as a VirtualMemory object
ram_usage = psutil.virtual_memory()

# Convert RAM usage to a dictionary for easy access
ram_usage_dict = dict(ram_usage._asdict())

# Get RAM usage as a percentage
ram_usage_percent = ram_usage_dict['percent']

Advantages of psutil

Using psutil for system status monitoring offers several benefits:

• Cross-platform compatibility: It works seamlessly across various operating systems.
• Comprehensive coverage: It provides detailed information not only about CPU and RAM but also virtual memory, disk usage, processes, and sensors.
• Easy to use: The API is clean and straightforward, eliminating the need for complex platform-specific code.
