Track NAS Clients - Is there a NetApp Tool?

Recently during a conversation with my manager regarding VMware Infrastructure Navigator he asked me if there was a comparable NetApp tool. I said I'd look into it. I'm not aware of a similar tool that would track all the dependencies of CIFS/NFS shares or volumes for all the NAS clients within the enterprise. I'm aware of most of the command line tools that i could use to check the sessions or clients or network connectivity to the vfiler, node or SVM but not sure if there is a tool for this in the NetApp suite of tools.  I'm wondering how everyone else keeps track of what is talking to the filers before a migration to new heads etc. Thank you for your wisdome and assistance.
