  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

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!
