service.ntp in triggers expression

[sauron]

Hello. I'm trying add new trigger for item service.ntp. I'm create expression:

{server:service.ntp.last()}=0


but when i'm try added this, i'm got:

[ERROR:Invalid trigger expression]

Expression [{alfa.core:service.ntp.last()}] does not match to [server:key.func(param)]


Why i'm got this ? It's wrong expression ?

Greetings,

Right off the bat, I suspect that you do not have an item defined for service.ntp on the server alpha.core. Double check that you have the item defined on the server alpha.core.

Ha! I'm found it! I'm added service.ntp this key service.ntp,ip,123. Where ip is my ntp server. Ofcouse i'm got bug when add trigger ;). I'm rewrite key to service.ntp, now it's working. Thanks for your explain ;)
