Hi Martin, thanks for your prompt response! the syntax I used here for aggregation is just the way I found it on mrtg-reference.
the suggestion you gave would really help me if you can give a clearer idea about in which part of mrtg .cfg file or in rrdtool I have to make change. or it may be an issue of mrtg itself. then I will post the problem to mrtg site. I am a newbee in the mrtg-rrdtool arena. your help would be higly appreciated.

When using rrdtool CDEFS directly: use ADDNAN instead of + in your CDEF - this will ignore the NAN As for how this works with MRTG - no idea...
