VERSION. 0.12.0
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, sampling, filtering and tagging and triggers. Libpcap, Netlink/ULOG, 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-0.12.0.tar.gz CHANGELOG. + 'is_symmetric' aggregation primitive has been implemented: aimed at easing detection of asymmetric traffic. It's based on rule definitions supplied in a 'bgp_is_symmetric_map' map, reloadable at runtime. + A new 'bgp_daemon_allow_file' configuration directive allows to specify IP addresses that can establish a BGP session with the collector's BGP thread. Many thanks to Erik van der Burg for contributing the idea. + 'nfacctd_ext_sampling_rate' and 'sfacctd_ext_sampling_rate' are introduced: they flag the daemon that captured traffic is being sampled. Useful to tackle corner cases, ie. the sampling rate reported by the NetFlow/sFlow agent is missing or incorrect. + The 'bgp_follow_nexthop' feature has been extended so that extra IPv4/IPv6 prefixes can be supplied. Up to 32 IP prefixes are now supported and a warning message is generated whenever a supplied string fails parsing. + Pre-Tagging: implemented 'src_local_pref' and 'src_comms' keys. These allow tagging based on source IP prefix local_pref (sourced from either a map or BGP, ie. 'bgp_src_local_pref_type: map', 'bgp_src_local_pref_type: bgp') and standard BGP communities. + Pre-Tagging: 'src_peer_as' key was extended in order to match on BGP-sourced data (bgp_peer_src_as_type: bgp). + Pre-Tagging: introduced 'comms' key to tag basing on up to 16 standard BGP communities attached to the destination IP prefix. The lookup is done against the BGP RIB of the exporting router. Comparisons can be done in either match-any or match-all fashion; xidDocumentation and examples updated. ! fix, util.c: load_allow_file(), empty allow file was granting a connection to everybody being confused with a 'no map' condition. Now this case is properly recognized and correctly translates in a reject all clause. ! fix, sql_common.c: log of NetFlow micro-flows to a SQL database (nfacctd_sql_log directive) was not correctly getting committed to the backend, when sql_history was disabled. ! fix, mysql|pgsql|sqlite_plugin.c: 'flows' aggregation primitive was not suitable to mix-and-match with BGP related primitives (ie. peer_dst_as, etc.) due to an incorrect check. Many thanks to Zenon Mousmoulas for the bug report. ! fix, pretag_handlers.c: tagging against NetFlow v9 4-bytes in/out interfaces was not working properly. Thanks to Zenon Mousmoulas for reporting the issue. NOTES. Cheers, Paolo _______________________________________________ pmacct-discussion mailing list http://www.pmacct.net/#mailinglists
