HTTP tables
The two attribute groups created by the HTTP data source are:
- Managed URLs
- The Managed URLs table provides availability and response time data about each URL being monitored.
- URL Objects
- The URL Objects table contains a separate URL entry for each embedded object, such as the .gif and .jpg files that might be used in the website listed in the Managed URL report.
For information about the syntax used in the Managed URLs and URL Objects tables, see Specific fields for HTTP attributes.
When you need to monitor the response time and availability of specific objects within a website, review the contents of the URL Objects table. The URL Objects table monitors a specific list of objects detected in downloaded HTML files. The following table lists the HTML elements that are searched for objects to monitor and the attributes within these elements that reference the objects:
| HTML element | Attribute containing object to be monitored |
|---|---|
| img | src |
| script | src |
| embed | src |
| object | codebase or data |
| body | background |
| input | src |
In the following example HTML extract, the object monitored is the image referenced by the src attribute of the img element.
<img src="/v8/images/id-w3-sitemark-simple.gif" alt="" width="54" height="33" />
A full URL to the image is calculated based on the URL to the source document.
