 * service).
 *
 * Implementations, such as SDKs, are recommended to generate a random Version 1 or Version 4 [RFC
 * 4122](https://www.ietf.org/rfc/rfc4122.txt) UUID, but are free to use an inherent unique ID as the source of

 * **SHOULD** use the following UUID as the namespace: `4d63009a-8d0f-11ee-aad7-4c796ed8e320`.
 *
 * UUIDs are typically recommended, as only an opaque value for the purposes of identifying a service instance is
 * needed. Similar to what can be seen in the man page for the
 * [`/etc/machine-id`](https://www.freedesktop.org/software/systemd/man/latest/machine-id.html) file, the underlying
 * data, such as pod name and namespace should be treated as confidential, being the user's choice to expose it
 * or not via another resource attribute.
 *
 * For applications running behind an application server (like unicorn), we do not recommend using one identifier
 * for all processes participating in the application. Instead, it's recommended each division (e.g. a worker
 * thread in unicorn) to have its own instance.id.
 *
 * It's not recommended for a Collector to set `service.instance.id` if it can't unambiguously determine the
 * service instance that is generating that telemetry. For instance, creating an UUID based on `pod.name` will
 * likely be wrong, as the Collector might not know from which container within that pod the telemetry originated.
 * However, Collectors can set the `service.instance.id` if they can unambiguously determine the service instance
 * for that telemetry. This is typically the case for scraping receivers, as they know the target address and
