Before using Zabbix, first understand the process of Zabbix monitoring:
When the collection value of the host monitor item (items) set by the Zabbix server satisfies the value set by the trigger (triggers), the corresponding alarm action (actions) is generated, and the police-style is set up by the specified user (Media Types) to notify the relevant personnel to handle.
1 Create a group of monitoring devices, the same device can be added to the same group for easy management, in Configuration->hosts->host group->create Host Group can add device groups, group name is web_groups.
2) Add host, in the Configuration->hosts->hosts->create host to add the monitored hosts, add the hostname as Zabbix, device group for web_groups.
3 Create template templates in Configuration->hosts->templates->create.
Fill in the name of the custom template Nginx_tem, and link the system custom Template_linux to the template.
