From Netmon
Netmon can monitor websites and web applications by analyzing the results of an HTTP request. You can use this service to monitor your corporate website, company intranet, or any other web-based system.

Introducing the URL Tracking Service
Netmon requests a user-specified URL at user-configurable intervals. It receives the resulting HTML web page (or XML, or any other HTTP payload) and inspects the contents for a user-specified text pattern.
If Netmon finds a matching copy of the text pattern or phrase in the response, it assumes the website (or web application) is functioning normally. If Netmon does not find a matching string in the response content, it can be configured to queue an alert message.
Creating a New URL Tracker
To create a new URL Tracker, take the following steps.
1. Click the Trackers button in the top toolbar, followed by the URL Trackers button.
2. Click the Add New URL Tracker button.
3. Specify the desired URL in the URL text box. If you wish to include additional GET parameters, append them to the end of the URL in the usual querystring format (i.e. http://www.someweb.com/somescript.php?var1=true&var2=text)
4. Specify a text Pattern to use when matching the incoming HTTP response. You can specify a simple text string, or use a Regular Expression (PCRE) for more sophisticated matching capabilities.
5. Choose a monitoring interval, in seconds. In most cases, the 5 minute (300 second) interval is suitable.
6. Click the Create Tracker button.
Attaching Alerts to a URL Tracker
