"Improving" {HOSTNAME} is unreachable

[frater]

In the Windows template there's this trigger ({Template_Windows:status.last(0)}=2) which will show you if the Host is unavailable.
In this same template I also do a ping check to its Internet connection (icmp with an interval of 15 seconds).

When the Internet is down you will see 2 alerts.
1 for the Internet connection and one for the host. Of course I know I can disregard the status.last, but I would like to bring this logic into Zabbix itself.

I Surpress this trigger when I can't ping the site by "anding" it with "icmp.max(30)=0"

{Template_Windows:status.last(0)}=2 & {Template_Windows:icmp.max(30)}=0

This is AFAIK a good method, but because this is inside a template I have the risk of not getting an alert at all because I (or someone else) disabled the "icmp" item for that host for some reason (for instance the firewall can't be changed to respond to pings). The trigger will get disabled then.....

So I want to have a(nother) trigger that will go off in case the simple check is disabled. I hoped/expected a function like "item.disabled" which of course doesn't disable the trigger when the item is disabled but creates a value...

{Template_Windows:status.last(0)}=2 & {Template_Windows:icmp.disabled(0)}=1

Does such a function exist or anyone knows a workaround for this scenario?

For the time being I solved it like this.
In the template I create the normal trigger

{Template_Windows:status.last(0)}=2

which is disabled by default. If someone disables the simple check "icmp" in the host he should enable that trigger.
