Trigger update problem

[kayd]

Hello, Everyone

I'm trying to update trigger "Apache is not running on {HOSTNAME}" for default Template_Linux to match Ubuntu apache2 process.

Original
{Template_Linux:proc.num[httpd].last(0)}<1[/I]
My value
{Template_Linux:proc.num[apache2].last(0)}<1

It's exactly the same except process name, but I'm receiving "ERROR: Cannot update trigger".
How I can update this trigger in template?

Figured that out.
I had to edit corresponding item first, then trigger updated to apache2 automatically.
