[rrd-users] What's wrong on this

Hi all.

I'm newbie in rrdtool, but I almost understand this tool. I'm geting info
thought my 
snmp command based in Linux RedHat 7.2 using:  snmpget public 
. (example) each snmp value is saved in a perl script called
value 2 or value3.

I made my rrd database like:


# rrdtool create dbase1.rrd -s300  \
DS:valuea:GAUGE:600:U:U  \ 
DS:valueb:GAUGE:600:U:U \
DS:valuec:GAUGE:600:U:U  \
RRA:AVERAGE:0.5:1:288  \ 
RRA:AVERAGE:0.5:1:288  \ 
RRA:AVERAGE:0.5:1:288  \ 
RRA:AVERAGE:0.5:1:288   \
RRA:AVERAGE:0.5:1:288   \


I'm running my perl script wich contains the updates for each value. Every 
command called by snmpget is pasted into valuea, valueb and valuec, that's
way I fill this dbase1.rrd.

When I want to see what is contained in this rrd file, I get this values: 


# rrdtool fetch dbase1.rrd AVERAGE --start 1030986900
                   valuea        valueb        valuec

In my graph I can see graphed valuea, valueb, but not value c.

Each value is reciving information by memory usage from  a Cisco 2500 Router
each value is the same and not as different as it doesn't graph.

Can anyone help?

Please apologise my poor english.
