snmp安装[freebsd+redhat]+采集脚本

===============freebsd服务器====================================================

安装snmp服务

#cd /usr/ports/net-mgmt/net-snmp
#make
#make install

安装成功后

#vi /etc/rc.conf
添加

snmpd_enable="YES"
snmpd_flags="-a -p /var/run/snmpd.pid"
snmptrapd_enable="YES"
snmptrapd_flags="-a -p /var/run/snmptrapd.pid"

#/etc/netstart
修改snmpd.conf
#vi /usr/local/share/snmp/snmpd.conf  需要添加如下语句

rocommunity [ID] [ip]  采集服务器地址
exec .1.3.5.1.4.1.2021.52 game /bin/sh /home/zcy/game.sh

启动服务
#/usr/local/etc/rc.d/snmpd.sh start

#snmpdwalk -v 1  -c [ID] localhost 看是否有返回值

安装bsdsar

安装bsdsar这个程序来显示cpu的使用状态
cd /usr/ports/sysutils/bsdsar/
make install

修改/etc/crontab

# bsdsar execution
*/5 * * * * root /usr/local/bin/bsdsar_gather
0 0 * * * /bin/rm /var/log/bsdsar.dat
%~!*@#&#&注意存档/var/log/bsdsar.dat 不断增加我这里删除了每天凌晨

 

 

添加脚本

#cd /home
#mkdir zcy
#vi game.sh

安装snmp服务

ftp://rpmfind.net/linux/sourceforge/n/ne/net-snmp/net-snmp-5.2.2-1.EL4.i386.rpm
安装net-snmp的rpm包 net-snmp-5.2.2-1.EL4.i386.rpm

#rpm -ivh  net-snmp-5.2.2-1.EL4.i386.rpm

安装后启动/usr/sbin/snmpd -c /etc/snmp/snmpd.conf

这里snmpd.conf如下[snmpd.conf]redhat附

 

#snmpdwalk -v 1  -c [ID] localhost 看是否有返回值

添加脚本

#cd /home
#mkdir zcy
#vi game.sh
===========================================cpumemgesdiskinout.shell===================================

 

topsys=/home/zcy/tmp/top.tmp

top -n 1 b > $topsys
cpu=`cat $topsys | awk  '/^(Cpu)/{print $8}'`
memf=`free | awk  '/^(Mem)/{print $4}'`
#memt=`free | awk '/^(Mem)/{print $2}'`
gsecpu=`cat $topsys | awk  'NR==10 {print $9}'`
gsemem=`cat $topsys | awk  'NR==10  {print $10}'`

 

disk1=/
disk2=/data
disk1use=`df -k | awk 'NR==2 {print $5}'`
disk2use=`df -k | awk 'NR==3 {print $5}'`

 

infirst=$(awk '/'eth0'/{print $1 }' /proc/net/dev |sed 's/'eth0'://')
outfirst=$(awk '/'eth0'/{print $9 }' /proc/net/dev |sed 's/'eth0'://')
sumfirst=$(($infirst+$outfirst))
sleep 1
inend=$(awk '/'eth0'/{print $1 }' /proc/net/dev |sed 's/'eth0'://')
outend=$(awk '/'eth0'/{print $9 }' /proc/net/dev |sed 's/'eth0'://')

in=$(($inend-$infirst))
out=$(($outend-$outfirst))
