[Zabbix] SNMP TRAP 监控

时间 2021-01-10 标签 Zabbix 监控 snmp trap

1、安装关联包

# yum install -y net-snmp-utils net-snmp-perl net-snmp

2、下载zabbix-3.2.4 tar包

# cd /usr/local/src/

# wget https://nchc.dl.sourceforge.net/project/zabbix/ZABBIX%20Latest%20Stable/3.2.4/zabbix-3.2.4.tar.gz

# tar -zxvfzabbix-3.2.4.tar.gz

3、配置

# cp -a/usr/local/src/zabbix-3.2.4/misc/snmptrap/zabbix_trap_receiver.pl /usr/bin/

#chmod +x /usr/bin/zabbix_trap_receiver.pl

# vi /etc/snmp/snmptrapd.conf

disableAuthorization yes #不需要团体名

perl do "/usr/bin/zabbix_trap_receiver.pl";

# vi /etc/zabbix/zabbix_server.conf #或者编辑zabbix_proxy.conf

StartSNMPTrapper=1
SNMPTrapperFile=/tmp/zabbix_traps.tmp #该目录必须与zabbix_trap_receiver.pl脚本中定义一致

# systemctl restart zabbix-server

4、导入mib库

将mib库文件复制至 /usr/share/snmp/mibs 目录中并新建与配置 /etc/snmp/snmp.conf 文件。

mibs +JUNIPER-MIB:JUNIPER-FABRIC-CHASSIS:BGP4-MIB

5、重启 snmptrapd 生效

#systemctl enable snmptrapd

#systemctl restart snmptrapd

# netstat -tunlp |grep 162

udp 0 0 0.0.0.0:162 0.0.0.0:* 4620/snmptrapd

6、配置snmptrap 存档

# mkdir -p /var/log/zabbix_traps_archive

# vi /etc/logrotate.d/zabbix_traps

/tmp/zabbix_traps.tmp {
    weekly
    size 10M
    compress
    compresscmd /usr/bin/bzip2
    compressoptions -9
    notifempty
    dateext
    dateformat -%Y%m%d
    missingok
    maxage 365
    rotate 10

olddir /var/log/zabbix_traps_archive

}

7、测试

# snmptrap -v 1 -c public 127.0.0.1 '.1.3.6.1.6.3.1.1.5.4' '0.0.0.0' 633 '55' .1.3.6.1.6.3.1.1.5.4 s "eno16780032"

# more /tmp/zabbix_traps.tmp

8、配置zabbix web端

①新建模板 "TemplateSNMP trap fallback"

新建监控项：

Name: SNMP trap fallback

Type: SNMP trap

Key: snmptrap.fallback

Type of information: Log

②新建模板“Template SNMP traps” 并链接至模板“Template SNMP trap fallback”

新建监控项： snmptrap test

新建触发器
