Test overview

To go to the Test overview page, click a test name or Steps value in the Operational summary page.

When Dynatrace Synthetic is integrated with Dynatrace SaaS/Managed, you can drill down from synthetic tests in SaaS/Managed dashboards to the Test overview page in the Dynatrace Portal.

The Test overview page gives you comprehensive information at a glance for a selected test:

  • Performance and availability data for the test overall and for the test steps, measurement locations, and downloaded resources (objects).

  • Summary data for active alerts.

  • Identification of performance anomalies.

From this page, you can drill down through the Analysis workflow to investigate and resolve problems.

Test data

Click a tile at the top of the left pane to view data in that category. Data is displayed for the time frame selected at the top of the Portal window. You can change the time frame, selecting either a quick time frame or a custom time frame.

For each data tile, you can filter the chart and sort the table. Click an item in the legend to remove that item from the chart and filter the related list. Click a column head to sort the list in ascending or descending order.
