本篇博客就直接开门见山如何使用Zabbix Server 监控自定义item，其实这个案例我之前在用zabbix3.0时分享过。在zabbix 4.0版本上用法几乎一样。关于 Zabbix Server 和 Zabbix Agent 端的部署我这里就不废话。
一.在Zabbix Agent端编写自定义监控项
1>.查看默认的zabbix agent的item模板
[root@node102 ~]# cd /etc/zabbix/zabbix_agentd.d/ #我们将自定义的zabbix 的item放在该目录下！
[root@node102 zabbix_agentd.d]#
[root@node102 zabbix_agentd.d]# ll
total
-rw-r--r--. root root Feb : userparameter_mysql.conf
[root@node102 zabbix_agentd.d]#
[root@node102 zabbix_agentd.d]# tail - userparameter_mysql.conf
UserParameter=mysql.ping,HOME=/var/lib/zabbix mysqladmin ping | grep -c alive
UserParameter=mysql.version,mysql -V
[root@node102 zabbix_agentd.d]#
[root@node102 zabbix_agentd.d]#
2>.自定义zabbix agent 的item项
[root@node102 zabbix_agentd.d]# pwd
/etc/zabbix/zabbix_agentd.d
[root@node102 zabbix_agentd.d]#
[root@node102 zabbix_agentd.d]# cat monitor_file.conf #自定义监控项目
#Add by yinzhengjie
UserParameter=monitor_filesize,stat -c %s /etc/services
[root@node102 zabbix_agentd.d]#
[root@node102 zabbix_agentd.d]#
[root@node102 zabbix_agentd.d]# systemctl restart zabbix-agent #修改了上述的配置文件切记要重启服务！
[root@node102 zabbix_agentd.d]#
[root@node102 zabbix_agentd.d]#
[root@node102 zabbix_agentd.d]# ss -ntl | grep
LISTEN *: *:*
LISTEN ::: :::*
[root@node102 zabbix_agentd.d]#
[root@node102 zabbix_agentd.d]#
3>.检查监控项（item）是否生效
[root@node101 ~]# yum -y install zabbix-get.x86_64

[root@node101 ~]#
[root@node101 ~]# yum -y install zabbix-get.x86_64 #安装zabbix_get服务
[root@node101 ~]# hostname
node101.yinzhengjie.org.cn
[root@node101 ~]#
[root@node101 ~]# zabbix_get -s node102.yinzhengjie.org.cn -k monitor_filesize #发现我们可以获取到相应的数据啦！说明配置生效了！ [root@node101 ~]#
二.在zabbix添加自定义item的监控
1>.如下图所示，找到已经监控的我们上面配置的zabbix agent自定义监控项的主机中的item（如果主机未被监控，我们自己监控一下即可！）
2>.点击创建item
3>.添加自定义item
4>.item添加完成
5>.添加item完成后，需要确认是否获取到数据
三.监控httpd服务的80端口
1>.在zabbix agent 安装http并启动
[root@node102 ~]# yum -y install httpd
Loaded plugins: fastestmirror

* base: mirrors.aliyun.com
* extras: mirrors.aliyun.com
