This used to be a frequent discussion topic. There are three solutions.
1. Dump MRTG and use flow-tools/flow-stat for this information.
2. set up QOS and use the CAR MIB or the CISCO-QOS mib
3. write firewall rules on the server in netfilter and pull the
information from there.
IP accounting is almost never the appropriate solution. IP accounting
is a deprecated facility that was replaced by Netflow Switching in ios
11.0 (actually, there was undocumented support for it in 10.3.5 and
later in the core train). That was 7-8 years ago...
