# PROVIDE: flow_fanout
# REQUIRE: DAEMON
# KEYWORD: shutdown

#
# Add the following line to /etc/rc.conf to enable flow-fanout:
# flow_fanout_enable (bool):	Set it to "YES" to enable flow-fanout daemon.
#				Set to "NO" by default.
# flow_fanout_ip (str):		IP address to bind to
#				Default to "0.0.0.0"
# flow_fanout_remoteip (str):	IP address to accept flows from
#				Default to "0.0.0.0" or all IPs
# flow_fanout_port (int):	Port to accept flow data on
#				Default is "8787"
# flow_fanout_export (str):	Where to send flows to. Default is "0/0/8788"
# flow_fanout_flags (str):	Custom additional arguments to be passed
#				to flow-collector (default "").
# flow_fanout_profiles (str):	A list of configuration	profiles to enable.
#				This allows you	to run several instances of
#				flow-fanout with different parameters.
#				Consider the following example:
#				flow_fanout_enable="YES"
#				flow_fanout_ip="85.172.168.9"
#				flow_fanout_profiles="r1 r2"
#				flow_fanout_r1_port="4444"
#				flow_fanout_r1_export="0/0/9500 0/10.5.5.5/9200"
#				flow_fanout_r2_port="4445"
#				flow_fanout_r2_export="0/0/9551 0/0/9101"
#
#				This will run two instances of the flow-fanout
#				with parameters taken from appropriate
#				flow_fanout_PROFILENAME_xxx variables. For
#				unspecified parameters flow_fanout_xxx
#				varialbes will be used.
