We recently replaced a cisco router with an ImageSteam router, which runs on linux and I have to update the MRTG graphs to get the numbers for Eth0 and the CPU utilization, that is the only graphs I need off of the router. I easily get the entries in the main config file for the ethernet statistics but the CPU is proving to be more difficult. The version of MRTG we are running is 2.10.15 and it does not have the UCD-SNMP-MIB which is what appears to be required to get the ssRaw* info I need for the processor. Is there an area that I can put that Mib in the current load of MRTG so I can all it with Load Mib: or should I try to upgrade the version to solve the problem? The only problem with the upgrade is that there a lot of devices within this particular config. I have never upgraded or added a mib so I am aprehensive about my next step.
