Hi!I remember submitting a patch to Tobi that defines a CDEF called AVG, that does ignore NULL values. I now did check if this is in the SVN branch and I can confirm this is included.
Maybe this is what you can use...
MartinP.s: I remember having used a very complex CDEF to work around this for just 4 values and the patch to rrdtool was much shorter ;)

So for example, if you were not collecting samples for one system for a while, then you would have a gap in the graph.You have to do a test for unknown values and replace them with zeros before adding them all together. Have a look back through the archives, it's come up before._______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
