zabbix使用snmp自定义key

xingyu655

1、配置/etc/snmp/snmpd.conf文件增加如下配置，配置在重启snmpd服务后生效

extend .1.3.6.1.4.1.2021.52 regnum39 /etc/snmp/scripts/regnum.sh regnum39
extend .1.3.6.1.4.1.2021.52 regnum40 /etc/snmp/scripts/regnum.sh regnum40
extend .1.3.6.1.4.1.2021.52 totalregnum /etc/snmp/scripts/regnum.sh totalregnum

其中  .1.3.6.1.4.1.2021.52为自定义的oid，regnum39是key名称，/etc/snmp/scripts/regnum.sh是自定义脚本来获取数值，后面的regnum39是regnum.sh的参数

　　

2、zabbix-server上使用下面的命令获取相应的具体的值

[root@zabbix etc]# snmpwalk -v 2c -c public 10.84.10.166 .1.3.6.1.4.1.2021.52 #10.84.10.166为上面修改了snmpd.conf文件的主机ip

3、在zabbix的web界面增加item

注意snmp oid为snmpd.conf配置文件中的oid+snmpwalk获取到的后半部分

比如说，

regnum39这个key的snmp oid为 .1.3.6.1.4.1.2021.52.4.1.2.8.114.101.103.110.117.109.51.57.1

regnum40这个key的snmp oid为.1.3.6.1.4.1.2021.52.4.1.2.8.114.101.103.110.117.109.52.48.1

totalregnum这个key的snmp oid为.1.3.6.1.4.1.2021.52.4.1.2.11.116.111.116.97.108.114.101.103.110.117.109.1
