Manually creating resources to represent the deployment targets has always been challenging, especially when there is a large number of middleware instances such as CICS regions and DB2 databases. You will have to create tens, if not hundreds of resources, set properties on each resource to identify unique attributes of the target subsystem, come up with a structure to group them and eventually you may have to review from time to time to make sure the resource model is up-to-date. The new zOS Management Facility plug-in allows you to automatically discover software instances provisioned by z/OS Management Facility or by z/OS Provisioning Toolkit. A collection of resources will be created in the resource tree to represent the software instances. Following picture shows an example of the discovery result.
