You can configure the thresholds that define slow, very slow, and stalled end-user requests. These thresholds are used to trigger browser snapshots. See Transaction Thresholds for a detailed discussion about static, dynamic, percentage, and standard deviation thresholds.

You can define Browser Monitoring thresholds as one of the following:

  • a multiple of the standard deviation. The default standard deviation threshold duration is two hours. For example: "Experience is slow if end-user response time is slower than 3 X the standard deviation." 
  • a static value; For example: "Experience is stalled if end-user response time is slower than 30000 ms."

The default thresholds are:

  • Slow = 3 x standard deviation
  • Very Slow = 4 x standard deviation
  • Stalled = 45000 ms
