Ubuntu安装snmp

root@ubuntu:/etc/snmp# sudo apt-get install snmp snmpd

root@ubuntu:/etc/snmp# vim snmpd.conf

root@ubuntu:/etc/snmp# /etc/init.d/snmpd restart

root@ubuntu:/etc/snmp# snmpwalk -v 2c -c public localhost system

system: Unknown Object Identifier (Sub-id not found: (top) -> system)

root@ubuntu:/etc/snmp#

查看swap

root@ubuntu:/etc/snmp# snmpwalk -v 2c -c public localhost 1.3.6.1.4.1.2021.4.3.0

iso.3.6.1.4.1.2021.4.3.0 = INTEGER: 1107964

root@ubuntu:/etc/snmp#

centos安装snmp

[root@mail ~]# yum install -y net-snmp net-snmp-utils

其他可能需要的包有：

yum install -y net-snmp
yum install -y net-snmp-devel
yum install -y net-snmp-libs
yum install -y net-snmp-perl
yum install -y net-snmp-utils
yum install -y mrtg

可以将public修改为自己才知道的字符串，为了简便这里不修改

去掉view这行前面的#

将红方框上面的行，转换成红框内容

启用全部功能

[root@mail snmp]# /etc/init.d/snmpd restart

测试：

[root@mail snmp]# snmpwalk -v 2c -c public localhost 1.3.6.1.4.1.2021.4.3.0

UCD-SNMP-MIB::memTotalSwap.0 = INTEGER: 1015800 kB

[root@mail snmp]#

[root@mail snmp]# snmptranslate -To|head

输入OID查看系统信息的方法比较麻烦，所以可以使用mlib

Ubuntu安装mlib

安装mibs

root@ubuntu:/etc/snmp# sudo apt-get install snmp-mibs-downloader

root@ubuntu:/etc/snmp# sudo download-mibs

配置：

root@ubuntu:/etc/snmp# vim snmp.conf

将mibs注释掉，如下图

root@ubuntu:/etc/snmp# /etc/init.d/snmpd restart

检查是否安装成功：

l root@ubuntu:/etc/snmp# ls /usr/share/mibs/

iana  ietf  netsnmp

root@ubuntu:/etc/snmp#

 

root@ubuntu:/etc/snmp# snmpwalk -v 2c -c public localhost ifInOctets

IF-MIB::ifInOctets.1 = Counter32: 622063

IF-MIB::ifInOctets.2 = Counter32: 13430504

 

root@ubuntu:/etc/snmp# snmpwalk -v 2c -c public localhost ifInOctets|awk -F '::' '{print $2}'

ifInOctets.1 = Counter32: 622509

ifInOctets.2 = Counter32: 13463521
