Scheduling an Nmap Scan

After Nmap replaces a host’s operating system, applications, or servers detected by the system with the results from an Nmap scan, the system no longer updates the information replaced by Nmap for the host. Nmap-supplied service and operating system data remains static until you run another Nmap scan. If you plan to scan a host using Nmap, you may want to set up regularly scheduled scans to keep Nmap-supplied operating systems, applications, or servers up to date. If the host is deleted from the network map and re-added, any Nmap scan results are discarded and the system resumes monitoring of all operating system and service data for the host.

In a multidomain deployment:

You can schedule scans only for your current domain
The remediation and Nmap targets you select must exist at your current domain or an ancestor domain.
Choosing to perform an Nmap scan on a non-leaf domain scans the same targets in each descendant of that domain.
