[mrtg] Trouble graphing CPU & MEM load on a 3COM Netbuilder-II

[Olivier Lemaire]

Greeting all,

    I'm trying to graph the CPU & MEM Load of a 3COM Netbuilder-II
router using MRTG (version 2.8.6 on a Linux box, kernel 2.2.5, GD libs
release 1.3.6).

    Thank's to David C Prall from DCP Technologies, I found th OIDs
related to CPU & MEM :
1.3.6.1.4.1.43.2.13.8.4 : for CPU Load
and
1.3.6.1.4.1.43.2.33.1.2.1 : total MEM on board
1.3.6.1.4.1.43.2.33.1.2.2 : Free MEM (in fragment)
1.3.6.1.4.1.43.2.33.1.2.3 : Used MEM (in fragment)

    Thank's to James Liakos, I tried to configure my mrtg.cfg file like
that :
WorkDir: /my/working/dir/
#Router CPU Load
Target[my-router-IP.cpu]:1.3.6.1.4.1.43.2.13.8.4:public at my-router-IP
RouterUptime[my-router-IP.cpu]:public at my-router-IP
MaxBytes[my-router-IP.cpu]:100

Legend4[my-router-IP.cpu]:
LegendI[my-router-IP.cpu]:
LegendO[my-router-IP.cpu]: &nbsp;Usage

But it don't seems to work very well as I only get that kind of error
message :
(My rooter IP address is 160.128.3.13 as you can see in this message)

I tried multiple times!

I tried some other OIDs (mem for example), and always the same kind of
error message.

Anybody has a suggestion for me to make that graph work ?
