[rrd-users] Re: Loading extracted data

I guess you have missed a part of the tutorial.

>        DS:disk1:GAUGE:600:U:U \

Try something like:

        DS:disk1:GAUGE:3600:U:U \

Importance: Low


Hi folks, 

I try to load data extracted from a database to rrdtool for graphing.
The values are get every 30 minutes, So I have try : 

I have generate this rrd :  

$RRDTOOL_PATH create $RRD_PATH/disk.rrd\
         --start 1054420000 \
         --step 1800 \
        DS:disk1:GAUGE:600:U:U \
        DS:disk2:GAUGE:600:U:U \
        RRA:AVERAGE:0.5:1:600      \
        RRA:AVERAGE:0.5:6:700      \
        RRA:AVERAGE:0.5:24:775     \
        RRA:AVERAGE:0.5:288:797    \
        RRA:MAX:0.5:1:600          \
        RRA:MAX:0.5:6:700          \
        RRA:MAX:0.5:24:775         \
        RRA:MAX:0.5:288:797

Then : 

rrdtool update disk.rrd "1054422000:25.17:25.17"
rrdtool update disk.rrd "1054423800:25.15:25.15"
[...]
rrdtool update disk.rrd "1055455200:33.83:33.83"
rrdtool update disk.rrd "1055457000:33.83:33.83"

When I fetch the values, I get nothing : 
rrdtool dump disk.rrd |grep -v NaN

                <database>
                </database>
        </rra>
</rrd>


This seems to lock me only when loading old values in batch, when I
monitor in real time, everything is ok.
I don't understand what's wrong with this method !
