This tool provides the following monitoring capabilities:

• CPU Information: Usage percentage, core count, and detailed CPU info
• Memory Information: Virtual and swap memory usage
• Disk Information: Disk usage, partitions, and I/O statistics
• Network Information: Network interfaces, connections, and traffic statistics
• Host Information: System details, uptime, boot time, and users
• Process Information: Process listing, sorting, and detailed per-process statistics
