CentOS7.9下snmp v3 inform搭建监控端

1.基础环境配置

为了防止防火墙及selinux等的影响，需关闭防火墙及selinux等，具体参考：

Linux常规基础配置_linux基础配置-CSDN博客

2.安装snmp

yum源配置，具体参考：

Linux常规基础配置_linux基础配置-CSDN博客

snmp安装命令：

yum install -y net-snmp net-snmp-utils

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

3.监控端配置snmp v3 inform

1.编辑/etc/snmp/snmptrapd.conf文件，添加如下信息并保存

createUser watcher SHA "abcd1234" AES "abcd1234"
authuser log,execute,net watcher

[root@logstash snmp]# cat snmptrapd.conf 
# Example configuration file for snmptrapd
#
# No traps are handled by default, you must edit this file!
#
# authCommunity   log,execute,net public
# traphandle SNMPv2-MIB::coldStart    /usr/bin/bin/my_great_script coldcreateUser watcher SHA &#
