# Subnets to collect statistics on.  Traffic that
# matches none of these subnets will be ignored.
# Syntax is either IP Subnet Mask or CIDR
subnet 10.0.0.0 255.0.0.0
subnet 192.168.0.0/16
subnet 172.16.0.0/12

# Device to listen on
# Bandwidthd listens on the first device it detects
# by default.  Run "bandwidthd -l" for a list of
# devices.

# Options that don't usually get changed

# An interval is 2.5 minutes, this is how many
# intervals to skip before doing a graphing run
#skip_intervals 0

# Graph cutoff is how many k must be transfered by an
# ip before we bother to graph it
#graph_cutoff 1024

#Put interface in promiscuous mode to score to traffic
#that may not be routing through the host machine.
#promiscuous true

#Log data to cdf file htdocs/log.cdf
#output_cdf false

#Read back the cdf file on startup
#recover_cdf false

#Libpcap format filter string used to control what bandwidthd see's
#Please always include "ip" in the string to avoid strange problems
#filter "ip"

#Draw Graphs - This default to true to graph the traffic bandwidthd is recording
#Usually set this to false if you only want cdf output or
#you are using the database output option.  Bandwidthd will use very little
#ram and cpu if this is set to false.
#graph true

#Set META REFRESH seconds (default 150, use 0 to disable).
