about report DataDomain Filesystem Utilization

when I run this report I get 3 lines

/ddvar FS

Index FS

Data FS

My DD is used by Avamar and has Mtree for CIFS/NFS usage

just what is this telling me about the avamar data and Mtree data for the CIFS/NFS

I really want to be able to see what avamar is useing and what the CIFS/NFS using so I can see/predict the growth for both.
