How can use hostname macro for create a trigger on template

[bab]

I want add new item to my current template . So I need create a trigger for it : last(/server1/Time)=2
But as I have different hosts with different names how can create a macro on my template that can auto set hostname instead of server1?

There is no need to use any macro, in the template-level trigger configuration just use the template name (last(/mytemplate/Time)=2), it will automatically be replaced with the current host name when used in hosts.
