zabbix snmp、jmx配置使用

SNMP:

snmp是很古老的监控，我萌几乎可以在所有设备上看到它的身影

 [root@linux-node1 ~]# yum install net-snmp net-snmp-libs net-snmp-utils -y
 [root@linux-node1 snmp]# vim snmpd.conf
 [root@linux-node1 snmp]# grep "^[a-Z]" snmpd.conf
 syslocation Unknown (edit /etc/snmp/snmpd.conf)
 syscontact Root <root@localhost> (configure /etc/snmp/snmp.local.conf)
 dontLogTCPWrappersConnects yes
 com2sec admin  default       admin
 group   admin v2c           admin
 view    admin         included   .
 access  admin ""      any       noauth    exact  admin admin none
 [root@linux-node1 snmp]# systemctl start snmpd
 [root@linux-node1 snmp]# netstat -nulp
 Active Internet connections (only servers)
 Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name

 [root@linux-node1 snmp]# snmpget -v2c -c admin 192.168.56.11 .1.3.6.1.4.1.2021.10.1.3.
 UCD-SNMP-MIB::laLoad. = STRING: 0.07

页面上添加主机及snmp模版跟宏

这样就完成了，宏的名称为{$SNMP_COMMUNITY}，值为你snmpd里的团体名，一定要写对哦，否则是监控不到哒

JMX：
