Discovery maps hierarchical dependencies and assigns the appropriate relationship type between CIs that it finds.
Application dependency mapping (ADM) creates upstream and downstream relationships between interdependent applications by identifying which devices are communicating with one another, which TCP ports they are communicating on, and which processes are running on these devices.
All this information is used to automatically keep the ServiceNow CMDB up to date.
Discovery uses identifiers to search the CMDB for CIs that match devices discovered in the network. These identifiers can be configured to instruct Discovery to take certain actions when device matches are made, or not made, to maintain data integrity.
When IT uses VMware, AWS, or Microsoft Azure to make changes to their virtual or cloud environments, events from these environments trigger Discovery to detect those changes and then update the CIs and corresponding relationships.
This ensures up‑to‑date accuracy of the CMDB and real‑time visibility into virtual and cloud environments.
