Still working out all the details, but have had luck using logstash behind
lb to accept netflow inpup, then filter/output as desired...even back into
rsyslog. ;-)
input {
# Syslog inputs
udp {
host => "a.b.c.d"
port => 514
type => "syslog"
}
tcp {
host => "a.b.c.d"
port => 514
type => "syslog"
}
# Netflow input
udp {
host => "a.b.c.d"
codec => netflow {}
port => 2055
type => "netflow"
}
# Dummy TCP ports for load balancer probes
tcp {
host => "a.b.c.d"
port => 514
type => "dummy"
}
tcp {
host => "a.b.c.d"
port => 2055
type => "dummy"
}
}
Last tcp bits being a hack to keep random garbage showing up from lb
probes (my filters drop type dummy).
