x, custom expressions enable you to name transactions using getter chain(s) for HttpRequest properties and methods.

  1. Set the URI identification option.
  2. Click Apply a custom expression on HttpRequest and use the result in Transaction Names.
  3. Enter your custom expression getter chain as follows:
    • Enclose getter chain(s) inside braces: ${} .
    • Use getter chain syntax.
    • Use any HttpRequest request attributes or methods.

    For example, consider this URL: 

    The following custom expression uses two getter chains:

    • The first getter chain fetches the URL, splits it on the dash character ("-"), and uses the second string in the array.
    • The second getter chain fetches the HttpRequest.UserAgent property.
    • The literal dash character "-" separates the two getter chains. 

    No Format

    The result is the following business transaction name:

    Furniture-Mozilla/5.0 (Windows NT 6.3; Trident/7.0; rv:11.0) like Gecko
