Subject: PREDICT


Hello again dear experts,

I would like to use the functionality of CDEF and PREDICT, like this:

rrdtool.exe graph test.png DEF:value=mydb.rrd:count:AVERAGE CDEF:predict=600,-2,300,value,PREDICT LINE1:var#FF0000


but I get this error here:

ERROR: invalid rpn expression in: 600,-2,300,value,PREDICT


Why would this be? I am using RRDTool 1.3.30 on Windows. Do I need to use RRDTool version 1.4? If so, is there a Windows Binary I can download?


With kind regards, and thank you for your attention,


Michel
