[rrd-users] Cdef error in Tutorial example (newbie questions)

[Tom Sanders]

Sorry for such a newbie question.
General info:
Fedora Core 2 
RRDtool 1.0.41  
perl-5.8.3-18


Trying to get through the tutorial! 
I created the RRD with this. Straight from tutorial. Changed database
name.


>    rrdtool create testrouter.rrd         \
>             DS:input:COUNTER:600:U:U   \
>             DS:output:COUNTER:600:U:U  \

>             RRA:MAX:0.5:24:775         \

Have been snmp polling my router for a couple of day and the graph as octets works
great!  YEA!

This following works, straight from the tutorial.

>  rrdtool graph testrouter-day.gif --start -86400 \
>             DEF:inoctets=testrouter.rrd:input:AVERAGE \
>             DEF:outoctets=testrouter.rrd:output:AVERAGE \
>             AREA:inoctets#00FF00:"In traffic" \
>             LINE1:outoctets#0000FF:"Out traffic"

But when I try to convert to bits as below with a CDEF I get this error.
"rrdtool: No match."  What does this mean?  

This appears straight forward. What am I missing?

> rrdtool graph testrouter-day.gif --start -86400 -t "Test Router" -v Octets \
>             DEF:inoctets=testrouter.rrd:input:AVERAGE \
>             DEF:outoctets=testrouter.rrd:output:AVERAGE \
> 		CDEF:inbits=inoctets,8,* \
> 		CDEF:outbits=outoctets,8,* \
> 		GPRINT:inbits:MAX:"MAX bits IN=%lf%s" \
> 		AREA:inbits#00FF00:"In traffic" \
>                 LINE1:outbits#0000FF:"Out traffic"

Misc info: I also could not get the graph in the beginners guide, using 
"RRDs::graph" to work inline. I think CDEFs did not work there either.
 I got the following error at the point of generating the graph: 
> problem generating the graph: unknown function 'SCALAR'


Any Help would be much appreciated.
