This is a relatively unknown plugin for DFM/Operations Manager, now called OnCommand Unified Manager. The Plugin helps to answer a number of questions related to storage utilization and storage efficiency savings.  It also helps in identifying ways to improve the storage utilization.  It is implemented as a script that can be installed on the Operations Manager server.   The script can be scheduled for execution in Operations Manager and generates a set of web pages that provide an Efficiency Dashboard for the NetApp storage systems managed by Operations Manager.  Two primary charts are produced with additional charts to provide detailed breakdowns of how the storage space is being consumed.  These charts can be produced to represent all storage systems being monitored by Operations Manager, ‘groups’ of storage systems as grouped in Operations Manager or a single storage system. I wonder why they don’t include this as a tab inside OnCommand Unified Manager by default.
