Hello, At the moment I am trying to combine several RRD data files into one graph. I'm storing network traffic into the RRD files per IP address and I want to add all the data into one CDEF. I have the following command:
rrdtool graph test.png -s -1d -e now -t 'test graph' \ -l 0 -r -c GRID#666666 -c MGRID#888888 -w 495 -h 200 -a PNG \ -v 'bits per second' \ 'DEF:kbin1:/home/data/1.rrd:ds0:AVERAGE' \ 'DEF:kbout1:/home/data/1.rrd:ds1:AVERAGE' \ 'DEF:kbin2:/home/data/2.rrd:ds0:AVERAGE' \ 'DEF:kbout2:/home/data/2.rrd:ds1:AVERAGE' \ 'DEF:kbin3:/home/data/3.rrd:ds0:AVERAGE' \ 'DEF:kbout3:/home/data/3.rrd:ds1:AVERAGE' \ 'CDEF:totalkbin=0,kbin1,+,kbin2,+,kbin3,+' \ 'CDEF:totalkbout=0,kbout1,+,kbout2,+,kbout3,+' \ 'AREA:totalkbin#CBCCCF:' \ 'LINE1:totalkbout#B43F2E:' This works like a charm. However, when I want to add another DEF where the data in the RRD file starts later the whole graph starts at that time. Any data before the latest start time is not shown in the graph. Is there a way to avoid this? Thanks in advance. -- Hans _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
