      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 4
    -rw-r--r--. 1 root root 1531 Feb  4 02:03 userparameter_mysql.conf
    [root@node102 zabbix_agentd.d]# 
    [root@node102 zabbix_agentd.d]# tail -2 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 10050
    LISTEN     0      128          *:10050                    *:*                  
    LISTEN     0      128         :::10050                   :::*                  
    [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

    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
