IPA allows to make IP accounting (network accounting) based on IPv4/v6
Firewall and/or IP Filter accounting rules.

It supports limits for accounting rules and limits events as "limit is
reached", "reached limit is expired", etc. It understands time intervals
like "end of day", "end of week", "end of month", etc.

There is special viewer for accounting database and access control lists,
which allow or disallow one to view accounting information for rules.
