This would be nice, but we need to make sure the input is suitable for rrdtool graph. If the DEF command works on other datasources than RRDs, one side of this is done. The other side would be writing out processed data not to a graph but as text, like PRINT but now the complete series. > Also my favorite features would be: > > 1.

This is *very* similar to the stuff I'm currently working on. It will use variables which you can use in CDEF instructions something like: DEF:bytes=... CDEF:bits=bytes,8,* VDEF:perc=95,bits,PERCENT CDEF:high=bits,perc,-,100,LE,INF,UNKN,IF AREA:high#FF0000 AREA:bits#0000FF:bits LINE1:perc#FF0000:"95th percentile" cheers, -- __________________________________________________________________ / [EMAIL PROTECTED] [EMAIL PROTECTED] \ | work private | | My employer is capable of speaking therefore I speak only for myself | +----------------------------------------------------------------------+ | Technical questions sent directly to me will be nuked.
