Trigger that fires for every new occurence

[gellert.varga]

Hi everyone,

I want to set up a new trigger that fires (send e-mail) every time when a new occurrence added to an item.

I have an item like this:
log[C:\program\error.log,ERROR-]

I tried this trigger but it didn't work very well, because if two or more ERROR appeared in 30 sec the trigger fires only once:
{server:log[C:\program\error.log,ERROR-].nodata(30)}=0

Hope somebody can help to solve this problem.

Best Regards,
Gellert
