Q

What are the 3 action types?

A

Load Actions: Is defined as an actual page loading in your browser. If you type a URL in your browser and hit enter, a load action occurs. By default, load action names are based on the underlying HTML page name. (Ex. Loading of page index.html)

XHR Actions: Used in most modern applications, including single page applications. Page is changed via JavaScript and all communication with the web server is done via API calls - XmlHttpRequest(XHR) or via fetch(). By default, XHR action names are based on the XHR URL. (Ex. http://example.com/api/login)

Custom User Actions: Can be defined through JavaScript API for Real User Monitoring. For example, you could measure how long it takes to open a JavaScript-only drop-down menu or measure the duration of some JavaScript code.
