[rrd-users] Printing a single simple average value

[Ruttenberg, Tanya]

Hi RRD Users,

I have an rrdfile router1.rrd that collects utilization data every 15
minutes.  I want to print a single value which represents an AVERAGE
rate over a 6 week period.

I have read documentation and played around with this for several days
and I haven't been able to figure it out.

The closest I came was this:

rrdtool graph - -s "midnight-6w" -e "midnight" \
DEF:ds0=router1.rrd:ifInOctets:AVERAGE \
VDEF:ds1=ds0,AVERAGE \
PRINT:ds1:%20.2lf%s

At least this doesn't give me any errors, but it doesn't give me any
output whatsoever.

Ideally I want to put this into a perl script like:

$average = RRDs::graph($rrdargs);

What am I doing wrong?
