Being that no one has answered, I can only conclude that either no-one has managed to get HW working, or that it is broken.
which is it? -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Darryl Lewis Sent: Monday, 18 December 2006 5:13 PM To: [email protected] Subject: [rrd-users] Holt winters I'm trying to figure out how H-W forecasting works in rrdt. I changed a little simulation program that makes an rrd and graphs it in realtime, which I'm using to play with the variables and to experiment. I've got the following: DAY=1 GENERATIONS=60 PERIOD=$(($DAY * $GENERATIONS)) rrdtool create sim.rrd --start 'N' --step $DAY \ DS:sim:ABSOLUTE:$DAY:0:U \ DS:unk:ABSOLUTE:$DAY:0:U \ RRA:AVERAGE:0.1:1:$GENERATIONS \ RRA:HWPREDICT:$GENERATIONS:0.5:0.5:$GENERATIONS I get the following: ERROR: can't parse argument 'RRA:HWPREDICT:60:0.5:0.5:60' Any ideas? Also, the rrd help pages don't show how to graph it... rrdtool graph tmpgraph.gif --start -$PERIOD \ DEF:vsim=sim.rrd:sim:AVERAGE \ DEF:vunk=sim.rrd:unk:AVERAGE \ CDEF:real=vsim,$DAY,* \ CDEF:unrl=vunk,$DAY,* \ AREA:real#FF0000:"Number of spam messages" \ STACK:unrl#0000FF:"Number of false negatives" Any ideas what I need to add to get it to graph?
