Question 1

How to use sysinfo in a Docker container without installing Go?

Accepted Answer

You can build the demo utility in a Docker container using the provided link in the README, which compiles sysinfo without needing Go on the host system. This is useful for minimal or isolated environments where dependencies are limited.

Question 2

Sysinfo vs gopsutil: which is better for Linux hardware inventory?

Accepted Answer

Sysinfo is standalone with no external dependencies and focuses on static inventory, while gopsutil is cross-platform and includes dynamic metrics. Choose sysinfo for dependency-free, Linux-only static data; gopsutil if you need broader OS support or real-time monitoring.

Question 3

Does sysinfo work on Raspberry Pi or ARM-based Linux systems?

Accepted Answer

Yes, as long as the system runs a modern Linux kernel (4.2+), sysinfo should function on ARM architectures. However, specific ARM hardware details might not be fully covered, and you should test for compatibility in your target environment.

Question 4

How can I extract only storage information with sysinfo?

Accepted Answer

After calling si.GetSysInfo(), access the Storage field from the SysInfo struct, which returns an array of storage devices with details like name, driver, vendor, model, serial, and size, as illustrated in the sample JSON output.

Question 5

Is sysinfo suitable for cloud instance detection or virtualization?

Accepted Answer

The README doesn't explicitly mention cloud or virtualization detection. While it collects product and board info from SMBIOS, which might hint at virtualization, dedicated features for cloud environments are not included, so it may not reliably identify all cloud instances.

Question 6

Can sysinfo run without root privileges for basic info?

Accepted Answer

No, the README states that superuser privileges are required to access SMBIOS/DMI and RAM details. Without root, key inventory data will be missing, limiting its usefulness for comprehensive system information.
