snmp 默认监控upd161端口 tcp 也有

[root@bogon ~]# netstat -nlutp|grep snmp

nginx配置状态监控

zabbix IPMI snmp jvm    server-agent模式

yum install zabbix-server zabbix-web zabbix-server-mysql zabbix-web-mysql mariadb-server mariadb zabbix-agent -y

自定义监控项
[root@Zabbix-sever ~]# cat /etc/zabbix/zabbix_agentd.d/nginx.conf
UserParameter=nginx.active,/usr/bin/curl -s http://192.168.86.3:8080/nginx-status|awk 'NR==1{print $NF}'
重启zabbix-agent(注意看报错，这里修改)
在sever端使用zabbix_get测试获取
[root@Zabbix-sever ~]# zabbix_get -s 192.168.86.3 -p 10050 -k "nginx.active"

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

最终原因是由于
 rpm -ihv http://mirrors.aliyun.com/zabbix/zabbix/3.0/rhel/6/x86_64/zabbix-release-3.0-1.el6.noarch.rpm
装了6的rpm应该装7的zabbix repo

zabbix_get 使用，需要在zabbix_agent.conf中写入server的值，然后在server上执行get命令
[root@node1 ~]# zabbix_get -s 192.168.3.3 -p 10050 -k "system.cpu.load[all,avg1]"
0.270000
如果不是server执行的话：就会出现以下错误
[root@node1 ~]# zabbix_get -s 192.168.3.4 -p 10050 -k "system.cpu.load[all,avg1]"
zabbix_get [46203]: Check access restrictions in Zabbix agent configuration
