Module machine_id 

Host machine identifier, mirroring pkg/util/uuid.GetUUID() in the Go agent.

Platform	Source
Linux	/sys/class/dmi/id/product_uuid then /etc/machine-id → /proc/sys/kernel/random/boot_id
macOS	gethostuuid(3)
Windows	HKLM\SOFTWARE\Microsoft\Cryptography\MachineGuid
Other	""

All values are normalised to lowercase xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx. Returns "" on failure rather than a random UUID — the backend can detect a missing value but not a wrong one.

Functions

get_machine_id

Returns the host machine ID as a lowercase hyphenated UUID, cached for the process lifetime. Returns "" on failure or unsupported platforms.
