When Browser RUM is enabled, the JavaScript Agent collects browser snapshots for:

  • Every base page (including virtual pages), iframe, and Ajax request; these serve as a heartbeat snapshot
  • The slowest page for every region, every device, and every browser
  • Unique JavaScript errors; identified by script name and line number
  • Unique Ajax errors; identified by the HTTP error code in the Ajax response

For more information about browser snapshot collection, see Configure Browser Snapshot Collection.
