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?


My cpu/memory template for mrtg:

$head_lines .= <<ECHO
#.....................................................................
# Router processor utilization.
#

ECHO
;
