Hi all,
I'm having a really annoying problem with xnmgraph.
I'm trying to watch the CPU & Bandwidth of a router,
so i created the following scripts:

#!/usr/bin/ksh
#
/usr/OV/bin/xnmgraph -title "Router CPU" \
-geometry 600x400 -hidename True -poll 5s \
-mib
".1.3.6.1.4.1.9.9.109.1.1.1.1.3:CPU5sec:1::::::xxx.xxx.xxx.xxx"

#!/usr/bin/ksh
#
/usr/OV/bin/xnmgraph -title "Router Bandwidth" \
-geometry 600x400 -hidename True -poll 5s \
-mib
".1.3.6.1.2.1.2.2.1.10:ifInOctets_s1:7::::::xxx.xxx.xxx.xxx,
\

.1.3.6.1.2.1.2.2.1.16:ifOutOctets_s1:7::::::xxx.xxx.xxx.xxx,
\

.1.3.6.1.2.1.2.2.1.10:ifInOctets_s0:2::::::xxx.xxx.xxx.xxx,
\

.1.3.6.1.2.1.2.2.1.16:ifOutOctets_s0:2::::::xxx.xxx.xxx.xxx"

where xxx.xxx.xxx.xxx the loopback address of the
router.

When i run the scripts everything is fine for the
first 4-5 minutes, 
but then i get some irrelevant values (such as
22000000000 or -34000000000) 
with no reason and the graphs go crazy!

And here is the funniest part.
When i saved the graphs, i didn't find any "strange"
values inside.
So i recreated the graph.
When i zoomed in the "strange" values were there!!

When i tried to see the statistics the values seemed
to be ok.

Am I missing something here?
Is it something known that i overlooked?
Any ideas?

Thanx in advance
Costas
