使用监控宝监控CentOS主机

一 配置SNMP
1.安装net-snmp
sudo yum -y install net-snmp
2.备份snmpd.conf文件
sudo cp /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf20150625

3.清空并重新编辑snmpd.conf

rocommunity  public   127.0.0.1
rocommunity  public   10.10.47.65
rocommunity  public   10.10.47.66
rocommunity  public   60.195.252.107
rocommunity  public   60.195.252.110

10.10.47.65是安装监控宝插件的那台主机的内网IP

4.重新启动snmpd

sudo service snmpd restart

5.验证snmpd是否已经启动
sudo netstat -tulnp|grep 161

在任意一台机器上执行以下操作
执行snmpwalk的机器需要在snmpd.conf中有记录
sudo snmpwalk -v2c -c public 10.10.47.65

NMPv2-MIB::sysORUpTime.8 = Timeticks: (2) 0:00:00.02
IF-MIB::ifNumber.0 = INTEGER: 2
IF-MIB::ifIndex.1 = INTEGER: 1
IF-MIB::ifIndex.2 = INTEGER: 2
IF-MIB::ifDescr.1 = STRING: lo
IF-MIB::ifDescr.2 = STRING: eth0
IF-MIB::ifType.1 = INTEGER: softwareLoopback(24)
IF-MIB::ifType.2 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifMtu.1 = INTEGER: 16436
IF-MIB::ifMtu.2 = INTEGER: 1500
IF-MIB::ifSpeed.1 = Gauge32: 10000000
IF-MIB::ifSpeed.2 = Gauge32: 0
IF-MIB::ifPhysAddress.1 = STRING:
IF-MIB::ifPhysAddress.2 = STRING: 52:54:0:8b:f2:fc
IF-MIB::ifAdminStatus.1 = INTEGER: up(1)
IF-MIB::ifAdminStatus.2 = INTEGER: up(1)
IF-MIB::ifOperStatus.1 = INTEGER: up(1)
IF-MIB::ifOperStatus.2 = INTEGER: up(1)
IF-MIB::ifLastChange.1 = Timeticks: (0) 0:00:00.00
IF-MIB::ifLastChange.2 = Timeticks: (0) 0:00:00.00
IF-MIB::ifInOctets.1 = Counter32: 628285088
IF-MIB::ifInOctets.2 = Counter32: 3060855740
IF-MIB::ifInUcastPkts.1 = Counter32: 137622023
IF-MIB::ifInUcastPkts.2 = Counter32: 1929135244
IF-MIB::ifInNUcastPkts.1 = Counter32: 0

6.设置防火墙

如果被监控主机设置了防火墙需要开通UDP的161端口
iptables -I INPUT -p udp --dport 161 -j ACCEPT
