rrdtool 监控网络流量配置一例

rrdtool 监控网络流量配置一例，供大家学习参考。

首先，在被监控的机器上。

复制代码代码如下:

yum -y install net-snmp*
vi /etc/snmp/snmpd.conf

com2sec notConfigUser 10.10.10.210(这里写监控机的IP)   cctvcj
group   notConfigGroup v1           notConfigUser
group   notConfigGroup v2c           notConfigUser
view all    included .1                               80
access notConfigGroup ""      any       noauth    exact all none none

接下来，在监控机器上。

复制代码代码如下:

#!/bin/bash
set -x
rrd=/usr/bin/rrdtool
snmpwalk=/usr/bin/snmpwalk
pwd=cctvcj
dir=/usr/local/nginx/html
mkdir -p $dir

for host in 192.168.0.233 192.168.0.4 192.168.0.43
do

if [ "$host" = "10.10.10.125" ]
then
hostn="moshou"
elif [ "$host" = "192.168.0.4" ]
then
hostn="bjfms1"
elif [ "$host" = "192.168.0.3" ]
then
hostn="bjfms2"
elif [ "$host" = "192.168.0.233" ]
then
hostn="北京外网出口流量汇总图"
else
echo "no......................"
fi

$snmpwalk -v 2c -c $pwd $host IF-MIB::ifHCInOctets > ${dir}/${host}.in
$snmpwalk -v 2c -c $pwd $host IF-MIB::ifHCOutOctets > ${dir}/${host}.out

if [ "$host" = "192.168.0.233" ]
then
eth0_in=`snmpwalk -v 2c -c cctvcj 192.168.0.233 IF-MIB::ifHCInOctets.124|awk '{print $NF}'`
eth0_out=`snmpwalk -v 2c -c cctvcj 192.168.0.233 IF-MIB::ifHCOutOctets.124|awk '{print $NF}'`
else
eth0_in=`awk 'NR ==2{print $NF}' ${dir}/${host}.in `
eth0_out=`awk 'NR ==2{print $NF}' ${dir}/${host}.out`
eth1_in=`awk 'NR ==3{print $NF}' ${dir}/${host}.in`
eth1_out=`awk 'NR ==3{print $NF}' ${dir}/${host}.out `
fi

rm -f ${dir}/${host}.in
rm -f ${dir}/${host}.out

starttime=`date -d "1 days ago" +%s`

if [ -e "${dir}/${host}.rrd" ]
then
echo "${dir}/${host}.rrd is old" >> /dev/null 2>&1
else
$rrd create ${dir}/${host}.rrd --start $starttime \
--step 60 \
DS:eth0_in:COUNTER:600:0:1250000000000 \
DS:eth0_out:COUNTER:600:0:1250000000000 \

RRA:AVERAGE:0.5:288:600

$rrd update ${dir}/${host}.rrd N:${eth0_in}:${eth0_out}:${eth1_in}:${eth1_out}

#--width=500
$rrd graph ${dir}/${host}.png \

DEF:a="${dir}/${host}.rrd":eth0_in:AVERAGE:step=60 \
LINE1:a#00FF00:"eth0_in" \
GPRINT:a:AVERAGE:"\t 流进流量\:%8.0lf \n" \
DEF:b="${dir}/${host}.rrd":eth0_out:AVERAGE:step=60 \

done

效果图如下所示：
