1.在監控寶上監控一臺ubuntu主機。用傳統的方法有點不適合，搗鼓了很久，纔算監控到了數據
2.在ubuntu上安裝snmpd插件
sudo apt-get install snmp snmpd -y
sudo apt-get install snmp-mibs-downloader -y
ip=$(ifconfig eth1|egrep '(inet addr:)'|awk 'BEGIN{FS=":"}{print $2}'|awk '{print $1}')
sed -i s/127.0.0.1/${ip}/g /etc/snmp/snmpd.conf
sed -i s/mibs/#mibs/g /etc/snmp/snmp.conf
/etc/init.d/snmpd restart
3.編輯文件/etc/snmp/snmpd.conf
4.加入一行
access MyROSystem "" any noauth exact all none none
5.將原有“rocommunity public default -V systemonly” 的"-V systemonly" 參數去掉，變成：
rocommunity public default
rocommunity public x.x.x.x（授權ip）
6.將“#trap2sink localhost public”和“#informsink localhost public”前面的“#”去掉，改爲：
trap2sink localhost public
informsink localhost public
7.重啓snmp服務
service snmpd restart
8.在其他服務器上測試
snmpwalk -v 2c -c public 目標ip
