Re: [rrd-users] can not update rrd

Well, OK, thanks Alex...

At first sorry that I posted a Script which was plainly wrong.
Here's the working one:

RRD_BIN="/usr/bin/rrdtool"
RRD="/home/nkalle/rrds/test.rrd"
datum=`date +%s`
echo $datum

for i in `seq 1 10`; do

datum=`date +%s` #start-date
faselbla=`ifconfig eth0 | grep RX\ bytes | cut -d ":" -f2 | cut -d "
" -f1`
echo $faselbla
$RRD_BIN update $RRD $datum:$faselbla
sleep 60;
done
datum=`date +%s` #stop-date
echo $datum
exit 0;

Here's the command with which I created the Database:
rrdtool create test.rrd --step 60 --start 1171226200
DS:speed:COUNTER:90:0:U RRA:AVERAGE:0.5:1:12 RRA:AVERAGE:0.5:6:48

Here's the command I use to fetch the Data... and guess what... it works:

suse rrds # rrdtool fetch -s 1171226200 -e 1171228000
/home/nkalle/rrds/test.rrd AVERAGE
speed

Thanks for pointing this out by your "have a look at the Times in the
db" sort of answer... ;)
I have been brooding about this the whole Day...

Best Regards and Thanks
