This page describes browser snapshots. 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.
