Hi Uli! Assuming a DEF with the name of "val" here an example of a CDEF that will set all values above 1000 to NAN, which gets excluded in any calculations: "CDEF:fixedval=val,1000,GT,UNKN,val,IF" and graph "fixedval" instead of "val".
"man rrdgraph_rpn" gives you the documentation what else you can do with CDEFs. Or look at: http://oss.oetiker.ch/rrdtool/doc/rrdgraph_rpn.en.html Ciao, Martin Ulrich Stärk wrote: > Hi, > > I'm new to rrdtool so please be patient with me :-) > > I used ntop to populate some rrds and now want to generate custom graphs > from those.
