Hi!<br>
<br>
I remember submitting a patch to Tobi that defines a CDEF called AVG,
that does ignore NULL values.<br>
I now did check if this is in the SVN branch and I can confirm this is
included.<br>
Maybe this is what you can use...<br>

P.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 ;)<br>

Is there a maximum number of datasources in 1 graph?
Is there a maximum size of a cdef?
I've found that if I do this with only a few DS's, it works fine. Maybe
somebody has tried this before?

Are you aware that if ANY of the values is unknown them the result is
unknown ? 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.
