Hi All, I am facing a graphing problem while using CDEF's. I have already tried this question once on the mailing list, but maybe the question was not clear, so let me try again.
I have an rrd(say rrd1) created with a start of t and step 3600 and update it at t+3600. When I graph this one rrd, I get a straight line between t and t+3600. I have another rrd (rrd2) with a start time of t+3000 and step of 30 and have three updates at t+3030,t+3060 and t+3090. When I graph this, I get the expected graph starting from t+3000 and ending at t+3090. Now, I want to draw a combined graph with these two lines. The graph should use data from rrd2 and if the data is unknown at that time, it should use data from rrd1. I used this CDEF : DEF:val1=rrd1:<blah>... DEF:val2=rrd2:<blah>... CDEF:val3=val2,UN,val1,val2,IF LINE2:val3<blah>.... When I graph val3, I expect a line with rrd1 data from t to t+3000, then some lines with rrd2 data till t+3090 and then again rrd1 data till t+3600. But, Instead I see rrd2 data from t+3000 till t+3090 and then rrd1 data starting from t+3600 and ending at t+7200. This seems to be an inconsistency in the rrd graphing. My previous mail with the rrd statements is here : http://www.ee.ethz.ch/~slist/rrd-users/msg04686.html and the graph images are attached. I would appreciate any info on this. If people think there is a bug, I can go through the code to look at it. Else, please let me know if I am doing something wrong in the CDEF. This will save me from wading through the code.
