[rrd-users] rrdgraph issue

Hi everybody, i'm new to the list and also pretty new to the "deep" use 
of RRD; i mean that i always use rrd as a part of Network Monitoring 
tools like CRicket and, above all, OpenNMS.
Now i'm dealing with the graphing of some GAUGE values obtained from a 
perl script that give's back some ldap stats. My problem is how can i 
graph these values like, for example, "number of connection" per second ??
I mean: i make an snmpget of these OIDs every 5min ( 300 sec ), but if i 
don't use some CDEF on the variables, i only graph lines with values as 
they're obtained from the snmpget, and not related to seconds.
I read the docs on RRD webpage ( in particular those ones on CDEF and 
RPN ) , but i cannot understand the CDEF i have to implement.
Thanks in advance to everyone who can help me in solving this beginner 
problem !!!
