What happens if a device lacks an appropriate credential during discovery?

In the context of ServiceNow Discovery, when a device lacks the appropriate credential, the discovery process does not necessarily fail entirely; instead, the system attempts to connect using alternative service credentials. This flexibility is essential because it allows the discovery process to continue without being completely derailed by a lack of credentials for one specific device.

The system's ability to utilize alternative credentials means that it can still gather relevant information from other sources or services that the device may support. For example, if the primary SSH or Windows Management Instrumentation (WMI) credentials fail, the system can try other credentials that might be applicable, increasing the chances of successful discovery.

This approach enhances the overall effectiveness and robustness of the discovery process, allowing it to encompass a wider range of devices within the network even when some do not have the expected credentials. It promotes a more comprehensive inventory and visibility into the IT environment, which is critical for effective management and support.

In summary, ServiceNow Discovery is designed to be resilient, ensuring that the discovery process can adapt to credential limitations and maximize its chances of successfully uncovering and cataloging devices within the infrastructure.
