I would like to monitor the availability of a data driven page that has been known not to load due to being unable to create the temporary files required by the image resize function. It's happened a handful of times since launch in April/May and my host restarts the server to solve the problem - not sure that's the best way but that appears to be what they do. I'm uncertain as to whether uptime monitoring would inform me of failure to load the page in question as I'm not sure what exactly these types of services are checking. The availability of the site as a whole doesn't seem to be a problem, but the site's main purpose is to promote the business and advertise properties on its properties page and the availability of this page is, therefore, absolutely crucial to the likely longterm success of the site.

I know this is probably a very basic question, but if someone can point me in the right direction, I would be most grateful.
