An extraction domain is a subset of traffic to be examined. For example, you can apply a filter to limit the search to a specific range of IP addresses. Extraction domains enable you to focus resource-intensive content searches to limited subsets of the total traffic, which in turn enables you to create more content-based custom fields while maintaining a high level of throughput.

To define the subset of traffic to examine for data to collect in custom fields, create a custom field extraction domain. To perform this procedure, you must have Operator-level access, or higher.

To create a custom field extraction domain

  1. In the Real User Collector component, point to Administration > Data flow settings, and then click Custom field extraction domains.

  2. On the Action menu, click Create a new domain.
  3. Fill in the following fields:

Field

Description

Name

Identifier for your domain.

Traffic to my order processing app

Server IP address/mask 1

Specify the server IP address in the following way:
The server IP address and mask can be specified in the following ways:

  • As an IP address
  • As an IP/mask pair (no wildcards are allowed)
  • As an IP/CIDR pair (no wildcards are allowed)
  • As an IP address with wildcards (*). For example, 10.*.*.* matches any address that starts with 10.

    Note: All four quads must be specified, that is, 10.* is not a valid equivalent of the previous example.

    Separate multiple definitions by commas.
  • 10.1.2.3
  • 44.203.1.50
  • FE80::AC15:208
  • 10.1.2.3/255.255.0.0
  • 44.203.1.50/255.255.64.0
  • 10.1.2.3/25
  • 44.203.1.50/88
  • 1.*.3,44.*.*.50

Server ports

The server port can be a specific port or a range. Valid ports fall within the range of 0 to 65535. You cannot use wildcards (*).

  • 80
  • 443
  • 6000-6500

URL Host 1

The name of the host. You can use commas to separate multiple host definitions. You can also use wildcards (*).

  • www.bmc.com
  • mysite.*

URI 1

The URI is the part of the URL after the host name and before the question mark that indicates the beginning of query parameters (if any). You can specify more than one URI separated by a comma. You can also use wildcards (*). If commas or asterisks are required as part of the URI, they must be properly URL encoded.

  • *.html
  • /index*
  • /apps/servlet.jsp

MIME type 1

You can specify more than one MIME type, separated by a comma. You can also use wildcards (*).

  • text/html
  • application/*

1 At least one of these fields must be specified.

Note

If any of these fields contains a single wildcard (*) with no other text or is left blank, that field is treated as a wildcard.

To select values for server IP address/mask, URL host, URI, and MIME type, use the Reference list tool.

4. Click OK.

You can delete or edit a domain by selecting the corresponding option from the Action menu above the configuration panel.
