How to monitor the status/existence of a single service?

Question

Zabbix

I deal with the zabbix server, the task was set: to make a template with a trigger (or add to an existing one) that will monitor the status of one specific service.
For example, I need to monitor the status of only the EventSystem service so that the trigger fires if this service is running. If I make a trigger for one machine (for example, its name is test), I can write the following expression:
{test:service.info[EventSystem,state].min(3)}=0, but what expression should I write to monitor the machine to which this template is added without having to specify the machine name manually? This is what I can't understand

Answer 1

Instead of the name of the machine, write the name of the template.
