VERSION. 0.11.2
DESCRIPTION. 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 to store collected network data into memory tables or SQL (MySQL, SQLite, PostgreSQL) databases and export them 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, both unicast and multicast. Also, a client program makes it easy to export data to tools like RRDtool, GNUPlot, Net-SNMP, MRTG, and Cacti. HOMEPAGE. http://www.pmacct.net/ DOWNLOAD. http://www.pmacct.net/pmacct-0.11.2.tar.gz CHANGELOG. + 'sql_max_writers' configuration directive is being introduced: sets the maximum number of concurrent writer processes the SQL plugin can fire, allowing the daemon to degrade gracefully in case of major database unavailibility. + 'sql_history_since_epoch' is being introduced: enables the use of timestamps (stamp_inserted, stamp_updated) in the standard seconds since the Epoch format as an alternative to the default date-time format. + 'sql_aggressive_classification' behaviour is changed: simpler more effective. It now operates by delaying cache-to-DB purge of unknown traffic streams - which would still have chances to be correctly classified - for a few 'sql_refresh_time' slots. The old mechanism was making use of negative UPDATE queries. + The way SQL writer processes are spawned by the SQL plugin has slightly changed in order to better exploit fork()'s copy-on- write behaviour: the writer now is mostly read-only while the plugin does most write operations before spawning the writer. ! The list of environment variables passed to the SQL triggers, 'sql_trigger_exec', has been updated. ! Fixed a bug related to sequence number checks for NetFlow v5 datagrams. Thanks very much to Peter Nixon for reporting it. NOTES. None Cheers, Paolo _______________________________________________ pmacct-discussion mailing list http://www.pmacct.net/#mailinglists
