Step Duration

The Step Duration Chart, located on the Transaction Details page, lets you see the time individual steps of a transaction takes to complete.

AJAX calls are not included in step duration calculations.

This chart is interactive. Hovering the mouse over the chart will show each step duration for the selected time.

Beneath the chart the individual steps of the transaction are listed, showing the optimal threshold and 95% percentile for each step.

  • The optimal threshold (or typical value) can be edited on the Edit Transaction Monitor page.
  • The 95% percentile is a statistical concept indicating that for 95% of the time the step duration was below this figure.


Use the Zoom buttons to display data for 1 hour, 12 week, or 24 hours, or use the slider handles below the chart to create your own period. You can move the selected period to any point in the available data range using the slider bar.
