Call a URL from an action

[Monkey]

I have a few informational triggers that I want to perform an action on. I want these actions to call a simple web page - and pass in some information as URL parameters if I need to.

Right now I have:
{HOSTNAME}:wget http://example.org/script.php?IP={IPADDRESS}

This doesn't seem to be working. My thought is because of the {HOSTNAME} - since I am not running an agent on the machines triggering this alert. I really want the Zabbix server to call the URL listed. Can someone point me in the right direction?

if you want zabbix server to run the command, just use custom alert script (administration -> media types)
