[rrd-users] problems with update & cron?

I'm a bit of an rrdtool newbie, but what I'm trying to do is get the cpu
usage of our server.  I seem to be able to create the .rrd file ok:

RRDs::create ($rrd, "-b",$start,"--step",300,

and I'm using snmp to get user, system and idle times.  My update looks like

RRDs::update ("$rrd", "$t:$cpuuser:$cpusystem:$cpuidle");

the problem is when I update I get NaN if it is run from cron (Solaris 2.6),
but if I manually update it gets there ok.

What am I doing wrong?
