Is it possible to enable specific trigger on specific server only, by automatically?

[EvilEugene]

Hello all,
I want to monitoring swap usages, but only DB servers.
I tried to add 'system.swap' item to mysql template, but It was already registered in another template(linux template), thus I can't add it.
so I create trigger for swap usages in linux template, and make it disable by default.

now, all of my servers has this trigger, but disabled.
how can I enable it ONLY on DB servers?
Is there any solution for this?

thanks for help

Remove those item and trigger from linux template and add it to mysql template.

Thanks for response, Semiadmin.
but the other servers also need to check swap usages.
so I think moving it to mysql template isn't good solution...

I'll find another way. thanks
