Most of the times this is due to different PATH settings.
Always use full paths for your commands when run from cron will help.

Not that I know of but you could write your own:
MRTG will have about 300 lines worth of 5-minute samples.  You could
get these lines every midnight and merge them with your own logfile.

Something like:
(mylog is the log you want to keep; not an mrtg log)

   mv mylog mylog.old
   head -300 mrtg.log | tail +4 > mylog.new
   cat mylog.new mylog.old | sort -u > mylog
   rm mylog.old mylog.new

Add some checking, redundancy, whatever.
