You're right, the check should only happen every 2 mins
(normal_check_interval).
But what looks strange to me is the check_command.
Do you actually have command definition called "check_http - vhost - url -
string" ? I'm not sure if spaces are allowed in the definition.
Can you post the command definition?


What happens if you change the check_command to the following:

check_command    check_website!www.website.com!-u /

where the command definition of check_website looks like that:

define command{
        command_name    check_website
        command_line    $USER1$/check_http -H $ARG1$ $ARG2$
        }
