HTTP Content

The HTTP Content monitor requests a URL and checks the HTTP response against the expected content. If the response does not return the expected content, the monitor fails. You can use this monitor to ensure web page/web server availability, to check if a page renders properly on specific browsers, or even to check for the presence/absence of specific content. If the monitor does not find the specified content, the monitor is considered Down.

Provide a unique name and description for the monitor, then configure the following:

Note: This monitor only supports basic authentication.

Click Advanced to configure the user agent and custom headers if desired:

Important: Errors can result when using invalid custom headers or when modifying headers which do not allow modification, such as the HTTP Host header. Click Request URL contents in the monitor configuration interface to test custom headers. If a problem with the header exists, WhatsUp Gold displays an error message. For example, the message "An error occurred with the requested website. Error: The 'Host' header cannot be modified directly. Parameter name: name." indicates the user entered Host:myhost.com as a custom header when the Host header cannot be modified.

Example Content URLs

To check content for the default page of a newly installed IIS server:

http://my-device/iisstart.htm

—where my-device is the hostname or IP address where a fresh instance of IIS is running.

To see how the HTTP Content monitor works, you can test it against one of the example documentation pages hosted by the Internet Assigned Numbers Authority (IANA):

http://www.example.com
