gopsutil is a system information library for Go that retrieves CPU, memory, disk, network, and process details from the operating system.
The tool solves the problem of accessing low-level system metrics and process information in Go applications without requiring direct system calls or external dependencies. It works by providing a cross-platform API that abstracts away differences between operating systems, allowing developers to query the same information whether running on Linux, Windows, macOS, or other supported platforms. The library returns structured data about system resources, running processes, and hardware configuration that applications can use for monitoring, diagnostics, or resource management.
Developers should choose this library when building system monitoring tools, performance dashboards, container orchestration systems, or any application that needs to inspect system state programmatically. It suits projects that require portable code across multiple operating systems without the overhead of spawning external processes or parsing command-line tool output. The library is particularly valuable for applications that need to avoid cgo dependencies while still accessing detailed system information.
The project maintains steady activity with regular updates addressing platform-specific issues and expanding support for additional metrics. Contributions flow in consistently to handle edge cases across different operating system versions and architectures. The maintainers respond to issues and pull requests, indicating active stewardship of the codebase. The project has accumulated substantial usage across the Go ecosystem, suggesting it has proven reliable for production use cases.
