Or maybe it is just a typo? Ok, i used a 300 multiple as startdate, now i solved an error in graph.
Thank to you i got a good graph with Kbytes/s using this: # rrdtool create test.rrd --start 920804400 DS:bytes:ABSOLUTE:600:U:U RRA:AVERAGE:0.5:1:3600 # rrdtool update test.rrd 920804700:10 920805000:20 920805300:15 # rrdtool update test.rrd 920805600:10 920805900:40 920806200:20 # rrdtool graph speed2.png --start 920804400 --end 920806800 \ --vertical-label Kbyte/s \ DEF:speed=test.rrd:bytes:AVERAGE \ CDEF:rbytes=speed,300,*,1024,* \ VDEF:total=speed,TOTAL \ LINE2:rbytes#FF0000 \ GPRINT:total:"Total transfer\: %0.2lf MB" With VDEF i have the total for the delta between start and end. Now i would like to calculate 'partial series' for each step.. using the example i reported before, the series i would like to have is like this: 920804700:10 920805000:20 + 10 920805300:15 + 20 + 10 = 45 bytes between 920804700 and 920805300 and represent this as a function with a relative LINEX in graph. How can obtain this sums? Sorry but im not used to English mathematical language (or english at all)! :/ _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
