Connection Timeout on an http monitor application

it takes upwards of 3 minutes to load

The 300 seconds is applied to the overall transaction. However, there's some implementation behavior to ensure we don't get wait for something that's hung.

The server needs to send its headers within 100 seconds, or this exception occurs. This is the default behavior of the component used to handle http traffic. We don't have a setting that will allow modifying this behavior.

Perhaps there's another angle on getting what you're after. What does the page do that you want to monitor it? ( based on your description, I was thinking an SQL monitor that does the same query, and a http transaction on a fast responding page next to it ).
