Managing URL transformation rules

Using the pages accessed by navigating to the Configure > URLs menu you can define a data collection policy that determines how the appliance processes monitored URLs, and transforms them into URLs that appear in the database.

The development of your data collection policy can include the addition of site rules, path rules, query and variable rules, hints, page definitions, and advanced options. The following sections describe how to manage the information found in each page.

 
* 
IMPORTANT: Typically, URL transformation rules are established shortly after your appliance is initially installed and configured. If you make dramatic changes to the rules after the appliance has been monitoring and collecting data for some time, this can obsolete historical data in the database that may still show up in your reports. In this case, you may want to purge the page and hit resource list after modifying URL transformations.

For detailed information about URL transformation rules, see the following sections.

Defining site rules

Some web sites use aliases, as a means to redirect requests to another web site. For example, if you are monitoring the web site acorp.com, you may also be using aliases that include: acmecorp.com, acme.com, and acc.com.

Without configuring the aliases, the appliance stores the primary web site URL and its aliases in its database, and captured metrics are divided among the primary web site and each alias. In order to report metrics accurately, the data for aliases and the primary web site should be aggregated into a single entry in the database.

The Configuration > URLs > Site Rule page allows you to transform the site portion of the alias (information that appears before the .com) to the primary web site URL, creating a single site entry.

The transformation rule also helps to configure lengthy URL names that display in the Metric Analysis Page and Hit categories. Using the Site Rule, you can shorten the length of the URL by transforming the site name. For example, if you see acme.sectors.application.corp.com you can transform this site URL to acme.com.

Declaring site rules

This procedure explains how to configure site rules.

To declare site rules:
1
On the Site Rules page, click Add a Site Rule to display the Edit Site Rule page:
2
In the Find box, type the site name that you would like to execute from the URLs for Sites, Pages and Hits.
Alternatively, use Select Site and select the site from the Resource List.
3
Click Test to test the Find sting against the current list of URLs.
The Site Rule Test page displays a list of items from the resource list that match the Site Rule that you have entered in the Find box.
4
In the Display box, type the site name that you would like to see appear in the URLs for Sites, Pages, and Hits.
Alternatively, use Select Site and select the site from the Resource List.
5
Click OK to accept the new site rule.
The Site Rules section lists all define site rules.

Automatically discovering site rules

Automatically discovering site rules
1
On the Site Rules page, click the Auto-Discover Site Rules link if you would like the appliance to monitor the URLs in your traffic and suggest possible site rules to assist in transforming the URLs into a concise list.
The auto-discovery process examines network traffic and looks in URLs for the most common used site name. This is considered the primary site name. Next the process finds sitenames that are common in structure and compares them to the primary sitename.The system constructs possible site rules that will help to transform the site portion of the alias that are similar to the primary sitename. A list of site rules displays. You can select the site rules that you want to apply to the URLs.
During auto-discovery the following site names are not processed:
•
IP addresses
•
sites that do not contain a dot (.). For example site.com.
The page updates every few seconds expanding the list of site rules as they are discovered.
2
Click Stop at any time to stop the auto-discover process and use the site rules list that has been compiled up to that point. All site rules that have been detected appear in a checklist (see the following illustration).
