netsnmp-pcap - SNMP extension which captures network traffic and reports the number of packets captured, and the throughput
This program is a port of bsnmpd-pcap, the pcap plugin for FreeBSD's bsnmpd, as an AgentX for Net-SNMP, written in C using libpcap and libevent. It allows you to measure arbitrary network traffic, in packets or octets, using the pcap(3) library. Multiple flows of traffic can be measured by setting as many network monitors, with different filters.
To install this software, you need:
- a C compiler
- libevent2 (http://libevent.org/)
- libpcap (http://www.tcpdump.org/)
- Net-SNMP (http://www.net-snmp.org/)
Because the SNMP/AgentX component does not currently works, a program (bin/netsnmp-pcap-stats-reader) is provided to allow an easy integration of the results within Net-SNMP. This program needs Perl 5.8 or later with the additional modules: JSON::XS, SNMP::Extension::PassPersist
