Hi,
You can get the graphs on daily,weekly,monthly,3months,1year from the Ops-Man Web UI.
Graphs Beyond 1yr can be got from the dfm graph cli and the cli with help will give you all options.
There is no graph for NFS latency or Iops, but there is a report aggregated at d,w,m,y etc.
Below are the report names for the same.
dfm report | grep -i performance
storage-system-performance-summary performance summary of storage system
storage-system-NAS-performance-summary NAS performance summary of storage system
storage-system-SAN-performance-summary SAN performance summary of storage systems
aggregates-performance-summary performance summary of aggregate
volumes-performance-summary performance summary of volume
volumes-NAS-performance-summary NAS performance summary of volume
volumes-SAN-performance-summary SAN performance summary of volume
qtrees-performance-summary performance summary of Qtree
luns-performance-summary performance summary of LUN
disks-performance-summary performance summary of Disks
array-luns-performance-summary performance summary of array LUNs

For latency and other counters in graphical way,you will have to Performance Advisor.
Download the same from the web-ui, Control-Center-Setup-Download Management Console.
