Check results

If you have API or Browser checks running, you can select them on the main Checkly dashboard and get an overview of the results they have produced so far. To learn about heartbeat check results, visit the Heartbeat checks section

Check results overview

Select a check and you will see a breakdown of its recent runs, together with key availability and performance metrics.

Summary section

The summary at the top of the page allows for filtering based on the page’s data points and the selected timeframe and locations. Retried check runs do not influence this section; only the final results are considered.

Based on the user’s selection, the metrics in the summary will also be updated to show the most important numbers at a glance. Single tabs in the summary can be clicked to skip to the related section of the page showing a more detailed breakdown of the relevant information.

Time ribbon

Single check runs can be accessed by selecting them on the time ribbon or by hovering dots and clicking View Details. View Details will open the selected check run in a new browser tab; a simple click on a time ribbon dot will show a preview of the selected check run below it.

Selecting a check execution will take you to the dedicated check result page for it, which will look different based on whether you had been running a Browser or an API check.

When retries are enabled, an additional icon highlights that the check result contains multiple check runs. All attempts as well as the final result are available to view.

The check retries ratio indicates how many of the total checks run were retried due to an initial failed attempt.

For self-service plans check results will only be available in aggregate format after 30 days.


Depending on the type of check, different performance metrics will be shown in the Performance section.

For Browser checks, several performance metrics are shown in separate charts:

  1. The total duration of the browser session check overview browser session duration graph

  2. Load timings for the first page navigation check overview load timings graph

  3. A breakdown of different error types check overview errors graph

  4. An interactivity summary check overview interactivity graph

  5. A visual stability breakdown check overview visual stability graph

For API checks, a detailed response time breakdown is shown: check overview api performance graph

A performance comparison by location will also be included for both types of check: check overview location performance graph
