APM 2.0 for URL monitoring?

Anyone succesfully using APM 2.0 for monitoring website availability? I have run into a few problems when monitoring a site that is loadbalanced, if the site is stopped on one of the loadbalanced web servers the monitor is still reporting up. Any guidence on how this is done or examples of monitor configuration would be great.

How are your web servers being load balanced (round robin, MS NLB, Hardware load balancer)? This may be a clue into why this isn't working.

The web servers are load balanced by round robin.

A little more detail on the problem: We have a site running on two webservers that are LB (by round robin). When we configure the template for the given url on port 80 then assign the template to both servers the monitor turns green. The problem is when I stop the site on one of the servers the monitor for the template as well as both web servers stays green rather than going to yellow on the template and red on the failed server.

Have you considered monitoring by IP address instead of hostname or is that something you're looking to avoid? Feel free to straighten me out if I sound a little confused here.

To set up an HTTP component monitor to use the IP address of the current node in the HTTP request, type http://${IP}/ in the Url field.

To use both the IP address of the current node and the Port Number as defined in the HTTP component monitor, type http://${IP}:${PORT}/ in the Url field.
