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?
My cpu/memory template for mrtg:
$head_lines .= <<ECHO #.....................................................................
Router processor utilization.
ECHO ; snmpMIB_to_OID("/usr/share/snmp/mibs/CISCO-SMI-V1SMI.my"); snmpMIB_to_OID("/usr/share/snmp/mibs/CISCO-TC-V1SMI.my"); snmpMIB_to_OID("/usr/share/snmp/mibs/CISCO-PROCESS-MIB-V1SMI.my");
