Триггер работает не верно

[hatifnatt]

Здравствуйте.
Данные окружения такие
Zabbix 2.2.9
Debian 7.8 Wheezy

Есть такой триггер:

({TRIGGER.VALUE}=0 & {Template OS Linux:vfs.fs.size[{#FSNAME},pfree].max(300)} < 10) |
({TRIGGER.VALUE}=1 & {Template OS Linux:vfs.fs.size[{#FSNAME},pfree].min(600)}

...

Hi,

I would like some help on a issue.
I want to check vm.memory.size[pfree], but i dont want it to contain cached memory. Is there a way to do this smoothly? I am using 1.8.2 afaik, on a linux system.

Thanks in advance.
