I removed the gauge and I got now the graph. I understand that the router
has 2 CPU and of different OID, is it possible to have their Utilizations in
one graph like CPU1 & CPU2 Utilization. Thanks a lot

config file looks okay, as long as the returned values are below
100.
First, check what the router returns. You can do this with a tool
such
as "snmpget" on unix or "snmputil.exe" on windows. If the value
returned
is 0, there's nothing MRTG can do about it.
If the router does return values other than 0, check the mrtg log
file.
Look at the first few lines and do this again after five minutes.
The
values must change if everything works.
If there is something wrong with the values that are put in the log
file
and you are sure that the router does return values, chances are
that there
are errors during processing. Make sure that you don't trow away
your
error channel: calling "mrtg mrtg.cfg 2>/dev/null" is *wrong*
unless you
know what you are doing and why you are doing it.
Example (not a router cpu, doesn't matter in this case):
first:
[alex at home alex]$ head -4 home.cpu.log <http://home.cpu.log>
952166406 114891692 128752121
952166406 15 17 15 17
952166346 15 18 18 21
952166100 15 17 18 21
then:
[alex at home alex]$ head -4 home.cpu.log <http://home.cpu.log>
952166525 114893820 128754500
952166525 18 20 18 20
952166466 16 18 17 19
952166400 15 17 18 21
The values on each first line are the values that MRTG received.
They've
changed. In my example the values are not GAUGEs so the second line
will
show the resulting rate. In your case they should show the same (i
think).
If the values in the log file look OK, there is something wrong in
your
MRTG installation or with the web server. Make sure you are not
looking
at old, cached, images. Delete the x.x.x.x.cpu-day.png file, click
refresh in your browser and see if the image is missing.
