How to modify incorrect CDEFs in graph template?

Dear All

I want to monitor file system utilization, the php script has been invoked by "script server" of cacti 0.8.7b version, but the utilization always 100%, I did graph debug, and found there is something wrong with CDEFs. would you please instruct me to correct it in cacti? For details, please refer to following statements & pictures. thanks so much for your help, I am beginner at cacti.

Following is detail template information:

Data Query : SNMP - Get Mounted Partitions
Data Template : Host MIB - Hard Drive Space
Graph Template : ucd 90 Filesystems

This is output of RRD Graph Debug Mode:

I think the correct CDEFs should like this:

CDEF:cdefj=f,b,/,100,* \
CDEF:cdefba=e,a,/,100,* \
CDEF:cdefbb=h,d,/,100,* \

Incorrect utilization 100%

[gordon1023]

Resolution: Modify Graph Item in the graph template "ucd 90 Filesystem"

Focus on fields below:
Consolidation Function,
CDEF Function,
GPRINT Type
