zabbix启用snmptrap

安装应用

yum install -y net-snmp net-snmp-perl net-snmp-utils snmptt perl-Sys-Syslog perl-DBD-MySQL

下载MIB&&转换格式

cp inspur.mib /usr/share/snmp/mibs/INSPUR.txt
snmpttconvertmib --in=/usr/share/snmp/mibs/INSPUR.txt --out=/etc/snmp/snmptt.conf.inspur --net_snmp_perl

sed -i 's/FORMAT/FORMAT ZBXTRAP $aA/g' /etc/snmp/snmptt.conf.inspur

编辑 /etc/snmp/snmptrapd.conf

# snmp v2
authCommunity execute public
# snmp v3
createUser -e 0x0102030405 sipo SHA sipo@2021 AES sipo@2021
traphandle default /usr/sbin/snmptt

编辑 /etc/snmp/snmptt.ini

mode = daemon
net_snmp_perl_enable = 1
translate_log_trap_oid = 1
date_time_format = %Y/%m/%d %H:%M:%S
log_enable = 1
log_file = /var/log/snmptt/snmptt.log

snmptt_conf_files = <<END
/etc/snmp/snmptt.conf
/etc/snmp/snmptt.conf.inspur
END

编辑 /etc/sysconfig/snmptrapd

OPTIONS="-m +ALL -On"

编辑 /etc/zabbix/zabbix_server.conf

StartSNMPTrapper=1
SNMPTrapperFile=/var/log/snmptt/snmptt.log

启动服务

systemctl enable snmptrapd && systemctl start snmptrapd
systemctl restart zabbix-server

ps axu|grep snmp

测试snmptrap服务

snmptrap -v 2c -c public 192.168.8.155 'host-01' 1.3.6.1.4.1.2345 SNMPv2-MIB::sysLocation.0 s 'China'
主机名称, 可以为空: "host-01"	
Enterprise-OID: 1.3.6.1.4.1.2345	
数据OID: SNMPv2-MIB::sysLocation.0	
数据类型: s	
数据值: "China"	

snmptrap -u admin -l authPriv -a sha -A mypasswd -x aes -X mypasswd 192.168.8.155 'host-01' 1.3.6.1.4.1.2345 SNMPv2-MIB::sysLocation.0 s 'China'
