Hi there.
I was attempting to export the data in one of my rrd file... And I'm
puzzled with what I can retrieve..
rrd file was created with:
rrdtool create solarprodX.rrd --start 1252116540 -s 60 \
DS:power:GAUGE:300:0:U \
DS:total:DERIVE:300:0:2.3 \

Hi there.
Those are changes I've had for a long time on my local rrd copy. I
remember submitted them a long time ago on the RRD's trac, but it
seems to have got lost in the noise...
For 1.4 branch:
https://github.com/oetiker/rrdtool-1.x/pull/375
For master:
