I'd love to be able to create an alert and tie it to a specific page or directory on my site. So a "# of visitors" alert tied to a particular story that we've been doing a slow campaign on would be a nice way to get some confirmation. Another use case would be for pages which require significant amount of server work prior to serving. I'd like to set a pretty high server load time threshold for those pages.

Along the same lines, the "user/server page load" and "page goes down" alerts could be made a lot more useful by including the URL of the page that triggered the alert. It would allow me to make a more informed decision about whether or not to get out of bed at 3am (since I *know* some pages involve heavier lifting by the server or have a large payload for the user). Actually, it'd be great to know what the highest-density page is when a "total visitors" alert triggers as well, since it's more typical that one or two pages is responsible for crossing an alert threshold, not the site as a whole.
