You can customize the discovery process by using the discovery hook script files in the BASEDIR/smarts/rules/discovery/custom directory of the IP Manager installation area. Each discovery hook script is configured in such a way that it is invoked during a specific phase of the discovery:
This script is run by the IP Manager before a full discovery.
This script is run by the IP Manager before a system is discovered.
This script is run by the IP Manager after a system is discovered and before postprocessing.
This script is run by the IP Manager at the beginning of postprocessing.
This script is run by the IP Manager at the end of postprocessing.
You can customize discovery postprocessing by editing the ASL rule set in the custom-start-post.asl or custom-end-post.asl file. Here are two applications:
Edit the custom-start-post.asl file to rename devices after the devices are discovered and named by the IP Manager.
Edit the custom-end-post.asl file to unmanage devices in IP address ranges or with specific name patterns.
If there are groups of IP addresses that are not normally reachable by using ICMP polling, specify the IP ranges or matching criteria in the custom-end-post.asl file to ensure that the IP Manager will set the management state of these IP addresses to be unmanaged. The IP Manager will not ping IP addresses that are unmanaged.
IPs, devices, interfaces, ports, and other objects can also be unmanaged or managed through the Global Console by attaching the Global Console to the IP Manager and selecting the Unmanage or Manage menu option.
All methods for controlling the management state of objects are described in the VMware Smart Assurance IP Manager User Guide.
