System custom fields

The macro unmigrated-inline-wiki-markup from Confluence is no longer available.

provides the following system custom fields, which have customizable data sources, traffic selection, and transformations:

  • Session custom fields collect metrics and statistics specific to sessions.
  • Page custom fields collect attributes and metrics specific to pages.
  • Object custom fields collect attributes and metrics specific to objects.
  • Primitive custom fields extract data from the headers and content of HTTP requests and responses.

For any type of custom field, the system collects data first and then applies transformations or extraction rules. Because various reports and screens within the system use them, these fields must remain available, so you cannot delete or turn them off.

The following tables describe system custom fields.


Session custom fields


Page сustom fields


Object custom fields


Primitive custom fields

Note

Primitive is the only type of custom field that can pull information from the HTTP headers and content. For example, you can use a particular header for object type detection, or collect special content for page building.

You can use the data from primitive custom fields only with the grammar name on the Analyzer component. Use the export name only when you export from the Collector component to another application.
