pmacct is a small set of passive network monitoring tools to measure, account, classify, aggregate, and export IPv4 and IPv6 traffic. A pluggable and flexible architecture allows collected network data to be stored into memory tables or SQL (MySQL, SQLite, PostgreSQL) databases and exported through NetFlow or sFlow protocols to remote collectors. pmacct supports fully customizable historical data breakdown, flow sampling, filtering and tagging, recovery actions, and triggers. Libpcap, sFlow v2/v4/v5 and NetFlow v1/v5/v7/v8/v9 are supported. License: GNU General Public License (GPL) Changes:
The SQL UPDATE query code has been rewritten for increased flexibility. A new sql_locking_style directive, row or table granularity, is now supported in the MySQL plugin. Support for Endace DAG cards was introduced. The Linux cooked device (DLT_LINUX_SLL) handler has been enhanced by supporting 'src_mac' and 'vlan' aggregation primitives. A number of bugs have been fixed.
