Hi Todd!

Thanks for your answer.

For other users looking for this feature:
One can easily extract the bond interface statistics with SNMP. We did so with cacti and SNMP v2. Only standard templates are necessary:

Associated Data Query: SNMP - Interface Statistics
Associated Graph Templates: Interface - Errors/Discards, Interface - Traffic (bytes/sec, Total Bandwidth), etc.

Memory usage and load averages are also accessible. So far, I was not able to extract file space usage values.

Best regards,
