[rrd-users] Can't create graphic

[Adrian Gheorghe]

Hello everyone,

I'm sorry for posting such a simple question, but I've been trying to
make this work for some time now and it's very frustrating. I've tried
a couple of examples and everthing works ok, so my rrdtool
installation is ok and I'm pretty sure there's something I'm missing
but I simply can't see what - my script is very similar to the
examples.
So here it goes:

rrdtool create test.rrd --start 1165176000 --step 300
DS:download:GAUGE:600:0:U RRA:AVERAGE:0:1:1440

rrdtool update test.rrd 1165177800:95 1165178100:63 1165178400:79
1165178700:47 1165179000:83 1165179300:18 1165179600:87 1165179900:59
1165180200:65 1165180500:36 1165180800:43 1165181100:23 1165181400:19
1165181700:52 1165182000:11 1165182300:35 1165182600:46 1165182900:21
1165183200:59 1165183500:42 1165183800:74 1165184100:78 1165184400:38
1165184700:27 1165185000:62 1165185300:95 1165185600:75 1165185900:36
1165186200:31 1165186500:80 1165186800:14 1165187100:25 1165187400:43
1165187700:83 1165188000:62 1165188300:25 1165188600:92 1165188900:49
1165189200:74 1165189500:56 1165189800:75 1165190100:16 1165190400:70
1165190700:85 1165191000:59 1165191300:71 1165191600:19 1165191900:96
1165192200:83 1165192500:69

rrdtool graph asdf.png --start 1165179600 --end 1165183200
DEF:dw=test.rrd:download:AVERAGE

The output of the last command is: 0x0

The script should be very similar to this one:

work.

Thanks in advance,
Adrian.
