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