Template:FAQ:Agent 39

Not really.

There is an "Rmon" code module included within the agent source code tree, but this is best thought of as a template for the RMON-MIB statistics groups, rather than a full implementation.

With most MIBs, the hardest part of implementing the MIB is often getting hold of the data to report. This is definitely true of the RMON-MIB, which relies on gathering (and analysing) a potentially large quantity of network traffic. The Rmon code distributed with the Net-SNMP agent code avoids this problem, by using random data.

Some of the functionality of the RMON-MIB, such as the alarm and event groups, has since been superseded by the work of the DisMan IETF working group. The Net-SNMP agent does implement these (more general) MIB modules. But the statistics gathering aspects of the RMON-MIB are not readily available.

Note too that none of the core developers have any significant experience with this code, and the person who originally wrote it is no longer active on the mailing lists. So there's no point in asking on the lists whether these modules work or not. You've got the source - how badly do you need this functionality?
