Hello, Im web-scraping a stock-market page which is only open daytime, thus my rrd-database will have huge gaps in the data. I've been trying to make a CDEF that uses old values and tries to inter/extrapolate the gaps, but to no avail.
Can anyone shed some light regarding converting U to a straight line between the previous and last successful rrd data? I create the rrd with the following; rrdtool create stocklol.rrd --start $starttime -s 300\ DS:latest:GAUGE:600:0:U \ DS:volume:COUNTER:600:0:U \ RRA:AVERAGE:0.5:1:8640 \ RRA:AVERAGE:0.5:4:52560 The data is being updated 0800 -> 1800 CET, all other values are NAN / U Google and other sources doesnt hint on this, as far as i could tell. Alot of refrences to making unknown into 0, but that's absolutely not what i want. I checked the CDEF and RPN docs refrenced in rrdgraph pages. Sincerely, Joachim
