I would recommend using Cacti for
interface speed monitoring.
It is available at www.cacti.net
We need some fairly complex SNMP accounting software (data center) style stuff
that can monitor cisco equipment for bandwidth utilization and generate reports
based on 95th percentile and also perhaps even their actual
bandwidth usage (how many gigs of transfer they use per month, day, week.. etc)
Does anyone know of anything good that does anything like this? It needs to be
reliable? Can be open source, we’re using MRTG to track utilization but
we need something that really handles “accounting” for us.
