CentOS6.3环境下实战Linux开源流量监控软件Bandwidthd

####################################################

# Bandwidthd.conf

#

# Commented out options are here to provide

# documentation and represent defaults

# Subnets to collect statistics on.  Traffic that

# matches none of these subnets will be ignored.

# Syntax is either IP Subnet Mask or CIDR

subnet 10.1.3.0 255.255.255.0       #设置监控的网段

#subnet 192.168.0.0/24

subnet 172.16.1.0/24

# Device to listen on

# Bandwidthd listens on the first device it detects

# by default.  Run "bandwidthd -l" for a list of

# devices.

dev "any"  #(这是你要检测的网卡ethx或any(所有),可以调整为对应的网络连接设备)

# 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 1  #默认2.5 minutes 刷新

# Graph cutoff is how many k must be transfered by an

# ip before we bother to graph it

graph_cutoff 1024   #默认1M 以上的流量才有图形

#Put interface in promiscuous mode to score to traffic

#that may not be routing through the host machine.

#promiscuous true   #设置网卡在混杂模式中记录

#Log data to cdf file htdocs/log.cdf

output_cdf true   #在bandwidthd目录中生成log2.cdf  以log.cdf格式数据记录

#Read back the cdf file on startup

recover_cdf true   #在启动bandwidth时重新读取cdf的数据

#Libpcap format filter string used to control what bandwidthd see's

#Please always include "ip" in the string to avoid strange problems

filter "ip"   #以ip为过滤对象

#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    #图形生成

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

meta_refresh 150   #网页刷新时间
