Trigger for text

[sa22]

For example, this check:
web.page.regexp[192.168.0.1,index.php,80,OK,2]
returns string "OK"
How I should define a trigger for this check?

Ok, I'v found that trigger
web.page.regexp[192.168.0.1,index.php,80,OK,2].regexp(OK)
works fine
but how I can graph this data?

It's text data.
For graph use web monitoring http://www.zabbix.com/documentation/1.8/manual/web_monitoring, or web.page.perf[192.168.0.1,index.php,80]
