• System Information: OS details, hostname, kernel version, CPU count, memory, and uptime
• CPU Monitoring: Per-core CPU usage, frequency, and brand information
• Memory Analysis: Total, used, and available memory with visual usage bars
• Disk Information: Mount points, filesystem types, and space usage (limited in current sysinfo version)
• Network Statistics: Interface statistics and data transfer metrics (limited in current sysinfo version)
• Multiple Output Formats: Human-readable text and machine-readable JSON
• Colored Output: Beautiful terminal output with color coding
• Structured Logging: Built-in logging with configurable verbosity

cargo build
cargo build --release

Testing

cargo test

Running

cargo run
cargo run -- --help

Dependencies

• clap: Modern command-line argument parsing (v4 with derive features)
• sysinfo: Cross-platform system information gathering (v0.30)
• anyhow: Error handling
• serde: Serialization for JSON output
• colored: Terminal color support
• tracing: Structured logging

Current Limitations

Due to API changes in the sysinfo crate v0.30, some features are currently limited:

• Disk information display is not fully implemented
• Network statistics are not fully implemented

These features will be restored in future updates as the sysinfo API stabilizes.
