[mrtg] MRTG and Cable Modems

[Glenn Smith]

There's a directory called home/MRTG/modemstatus and I don't see a MRTG config file. But there was a cfg file in another directory which I believe is monitor only the ports on the CMTS device. So at this point, for the modems, I'll need to set this up from scratch. How to do this is my question, if the modems were not configured for SNMP and the bin files being handed out do not have any SNMP settings configured???? How then did MRTG monitor these modems before?

Thanks,
Glenn

At some point MRTG was also setup to monitor each modem status (Online/Offline) and it provided this information on an Intranet website. Currently the website does not have any information, it just stopped working.  We looked at the modem binary files but SNMP is not configured there to provide this information to MRTG.  Where else would I look and how do I configure MRTG/CMTS router to monitor cable modem status?  We currently running MRTG on CentOS.  Any direction would be greatly appreciated.
