Someone have tried scripts to monitor cpu, memory and temperature for cisco
routers, that work correctly in hobbit (also the rrd graphs)?

I'm tryng bb-xsnmp script, but i have some problems.

I do that using mrtg, and then run bbmrtg.pl to pull the stats into
hobbit.

Temperature monitoring has been flaky on Cisco for a long time - are you
using devices with good temperature reporting?

I have been using bb-xsnmp with BB in the past and really like it. Since
I rolled out HOBBIT the script isn't working. I really like bb-xsnmp
because it displays port status and description so I know what speed and
duplex and whats attached to each port. I haven't had time to figure out
why its not working (it creates the log file but doesn't write anything
in it) but will let you know when I do. 

Does anyone have any other suggestions of scripts they use to check
among other things speed/duplex and port descriptions?

The bb-xsnmp script, use the bb-combo.sh program, to send the results. I try
to copy it
from the bb installation, but it not work. Someone have tried it in a hobbit
installation?
Perhaps there is a environment variable problem?

I monitor many cisco devices (especially 7000 series), and generally i not
have temperature problems.

Thanks for your mrtg files, but i'm tryng to find a good script that are
compatible with  hobbit graphs generation
