You could continue collecting data yourself (perhaps just to a text file). Insert that data after the conversion is complete and you won't have lost any data. > Or is there any way inside the RRD system to do say "do this and that with > values smaler and/or larger then X". You can set up a CDEF from your data at graph time that ignores values smaller than X, then graphs that data rather than the recorded RRA data. -- Darren _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
