2. zabbix 配置 debug level

在 /etc/zabbix/zabbix_agentd.conf 中设置 DebugLevel=3

[root@mariadb-node-0 ~]# cat /etc/zabbix/zabbix_agentd.conf | grep Debug
### Option: DebugLevel
DebugLevel=3
[root@mariadb-node-0 ~]#

DebugLevel=5 则输出下面这样的日志：

[root@mariadb-node-0 ~]# tail -f /var/log/zabbix/zabbix_agentd.log
