Why Use this Watch Type?
The HTTP watch type is often used to determine if a web site’s content is being completely served at an acceptable response time by downloading a web page and analyzing its contents. The two measurements are Response Time - the amount of time that it takes for the packet to make a round-trip - and Content Verification – whether search text can be found in the content. An increase in Response Time may indicated network congestion or an overall increase in customer use of the web server.
What to monitor
Use the HTTP watch type to test web pages on a web site. It can be used to ensure that a web page not only loads, but loads completely – by checking for HTML tags. It can be used to ensure that dynamic pages are serving the correct content: If a database driven page encounters an error, the web site may still respond, but the web page will not have the intended content. Specify a search string to ensure the intended content is being served.
