[rrd-users] rrdtool update not updating?

[Kees Hoekzema]

Hello list,

I have a strange problem. I'm updating 3 rrd's every five minutes, with kind
large values.
The rrdtool update syntax is:

./rrdtool update eth0.rrd -t bup:bdown:pup:pdown
N:2097355983:374697312:149708474:360441474
./rrdtool update eth1.rrd -t bup:bdown:pup:pdown
N:106745808:2147483647:970334584:332227452
./rrdtool update cpugebruik.rrd -t user:system:idle
N:42500834:11578134:492644141

The first 2 won't work, while the third updates just fine.

Some more output:
./rrdtool fetch eth0.rrd AVERAGE
                      bup         bdown           pup         pdown
.... < skip > ....

1036246800: nan nan nan nan

./rrdtool fetch eth1.rrd AVERAGE
                      bup         bdown           pup         pdown
.... < skip > ....

1036246200: nan 0.0000000000e+00 9.6660000000e+01 7.8669658120e+00

The rrdtool creates:
./rrdtool create cpugebruik.rrd -s 300 \
    DS:user:COUNTER:600:0:100 \
    DS:system:COUNTER:600:0:100 \
    DS:idle:COUNTER:600:0:100 \
    RRA:AVERAGE:0.5:1:288 \
    RRA:AVERAGE:0.5:6:336 \
    RRA:AVERAGE:0.5:24:360 \
    RRA:AVERAGE:0.5:288:365

./rrdtool create eth1.rrd -s 300 \
    DS:bup:COUNTER:600:0:100 \
    DS:bdown:COUNTER:600:0:100 \
    DS:pup:COUNTER:600:0:100 \
    DS:pdown:COUNTER:600:0:100 \
    RRA:AVERAGE:0.5:1:288 \
    RRA:AVERAGE:0.5:6:336 \
    RRA:AVERAGE:0.5:24:360 \
    RRA:AVERAGE:0.5:288:365

./rrdtool create eth0.rrd -s 300 \
    DS:bup:COUNTER:600:0:100 \
    DS:bdown:COUNTER:600:0:100 \
    DS:pup:COUNTER:600:0:100 \
    DS:pdown:COUNTER:600:0:100 \
    RRA:AVERAGE:0.5:1:288 \
    RRA:AVERAGE:0.5:6:336 \
    RRA:AVERAGE:0.5:24:360 \
    RRA:AVERAGE:0.5:288:365


At this moment I can't think what is going wrong, maybe someone else has a
clue?
