# 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 is "0.0.0.0"
# flow_fanout_remoteip (str): IP address to accept flows from
# Default is "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
# variables will be used.
