![SNMP 监控](https://linux22.com/image/694431/SNMP%20%E7%9B%91%E6%8E%A7.png)
我尝试在 CentOS 中配置 SNMP 陷阱,但没有得到积极的结果。
目的:在 SNMP 代理上配置 SNMP 陷阱,以检查文件是否存在并将消息发送至 SNMP 服务器。
为了测试目的,我把“出口 1“ 进入/tmp/script1.sh而是检查某个文件是否存在。
下面是我的配置文件:
rocommunity public
trapcommunity public
group MyROGroup v2c readonly
view all included .1 80
access MyROGroup "" any noauth exact all none none
createUser testMonitor SHA testMonitor AES
rouser testMonitor
rwuser testMonitor
iquerySecName testMonitor
extend MyScript1 /tmp/script1.sh
monitor -r 60 "RunScript" .1.3.6.1.4.1.8072.1.3.2.3.1.4.9.77.121.83.99.114.105.112.116.49 !=0
monitor -r 60 "RunMyScript" nsExtendNumEntries.0 !=
snmpwalk -v2c -c 公共本地主机 NET-SNMP-EXTEND-MIB::nsExtendObjects
回到:
NET-SNMP-EXTEND-MIB::nsExtendResult。“MyScript1”= INTEGER:1
snmpwalk -v2c -c 公共本地主机 NET-SNMP-EXTEND-MIB::nsExtendObjects -On
回到:

我的问题:
如何正确配置 snmpd.conf 以自动检查 /tmp/script1.sh 退出代码以及如何将信息发送到 SNMP 服务器(snmptrapd)
此致!
