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.
