gopsutil is a Go library that provides a cross-platform interface to system information. It's a port of the popular psutil library for Python, aiming to provide similar functionality in Go. The project addresses the challenge of gathering system statistics consistently across different operating systems by leveraging platform-specific APIs and providing a unified Go interface. It aims to minimize differences between platforms while offering platform-specific data where necessary.
gopsutil distinguishes itself through its comprehensive platform support, offering a consistent API for accessing system information with platform-specific extensions. It addresses shortcomings in existing Go system information libraries by providing detailed hardware, process, and network statistics. The design leverages platform-specific structs and functions to maximize information availability and ease of use. It is porting information from cgo to native go structs.
- CPU Information: Provides details about CPU cores, models, frequency, and cache sizes across supported operating systems.
- Memory Information: Offers insights into total, used, free, and swap memory utilizing underlying system calls.
- Process Information: Enables access to process counts, CPU and memory usage, and other relevant process metrics on Linux, FreeBSD, and macOS.
- Network Information: Collects network statistics, interface details, and connection counts (Linux).
- Disk Information: Provides information about disk partitions, usage, and I/O counters (Linux, FreeBSD, OpenBSD, macOS).
- System Information: Gathers platform details like OS version, hostname, uptime, device information, and virtualization status.
- Docker Integration: offers detailed docker stats for Linux systems.
gopsutil is an active project with ongoing development and community support. Recent commits indicate continued maintenance and feature additions. The project has a solid release history with versioning following Semantic Versioning principles with calendar-based updates. Active issue tracking and a comprehensive documentation set suggest a healthy and responsive development process. Most facets of system information are implemented.
gopsutil is beneficial for system administrators, developers, and anyone needing cross-platform system monitoring capabilities from Go applications. It allows for gathering crucial system metrics for performance analysis, resource management, and automated system tasks. It offers a convenient alternative to manually querying system information or relying on platform-specific tools.
