Monitoring a matrix of load-balanced VirtualHosts?

[Chris Wilson]

Hi JB,

define service {
        use                     vhost-service
        service_description     www.bar.com
        check_command           my_check_http!www.bar.com
        hostgroup_name          bar_com_servers
}

define command {
        command_name    my_check_http
        command_line    $USER1$/check_http -I $HOSTADDRESS$ -H $ARG1$
}

This will call check_http with the host address (hostname) of each
server in the group "bar_com_servers". I've used a template,
vhost-service, to inherit the check interval and notification options
(not shown here).

> But if I'm trying to check the website "www.bar.com" on the host

As long as www.bar.com actually has a "/" page (it doens't return an
error or a redirect code).

Hope this helps,

Cheers, Chris.
