Hi, On one PC I run rrdtool v1.2.9. I can graph my data the way I like it. I want to migrate to a newer OS which has rrdtool v1.3.8. I dumped the rrd on the old installation and I restored on the new installation on a different PC. Then I ran the same command as the old installation to get a graph, but I get an empty image, i.e. there is no data. Rulers, text, etc. are OK. On the old installation I get a nice image. What am I doing wrong ?
I hope anyone can help. Regards, Koenraad Lelong. P.S. This is the command I used to graph a test-image : rrdtool graph test.png --start -13h24m50s --end +10h59m59s --width 550 --height 150 DEF:Power=pv_monitor.rrd:PAC:MAX LINE1:Power#FF0000: -u 3000 -v Watt -t hallo This should give a graph from past midnight to approx. next midnight (the real app. is more exact with the numbers). I tried to include a compressed dump of the rrd, and a good and a bad image, but then the mail is too big. Can I post those in separate mails ? P.P.S. The working installation is running on 64bit linux, the (temporary) new installation is running on 32bit Linux. I imagine this should not make a difference, since I use the dump. Right ?
