The Live Stream view, formerly known as Execution Center, provides information on the test executions currently running on devices in the Perfecto Lab. It allows you to view live videos and interact with these executions.

You can access current executions as follows:

  • Live Stream view: Displays information on your current executions. Administrator users see all executions. Two modes are available:
    • Device dashboard: Opens by default. Displays a video view of all executions currently running, provided you have permission to view them. Includes options to apply a filter, get more information on a specific execution, and view the video in full-screen view. 
    • Grid: Displays a table view of all executions currently running, provided you have permission to view them. Includes options to view the live video for an execution and to stop one or more executions.
  • HTTP API: Lets you retrieve test execution information of currently running executions in JSON format or stop a specific test execution. For details, see Execution Manager API.

In both modes, the Live Stream view displays the list of running test executions with the following information for each test run:


On this page:

Table of Contents

  • Identification: Execution name and owner, where the name is determined by the value of the scriptName capability defined in the test script.
  • Timing: The time the execution started (in the browser's local timezone) and the length of time the execution has been running (in minutes, seconds, and milliseconds)
  • Device: Characteristics of the device used for the test execution, as follows:
    • Device type: An icon that indicates whether the device is a mobile or desktop web device
    • Device model: For mobile, the device model; for desktop web, the VM operating system (Windows | Mac)
    • OS: The version of the operating system
    • Browser: If the test is running on a browser, an icon that indicates the type of browser and a number that indicates the browser version
    • Resolution: The display resolution of the device
    • More: Any additional information regarding the device, if applicable

The header, with the total number of executions running and the Search field on the right, is the same for both modes.


Note: By default, an automatic timeout occurs after 15 minutes of inactivity. If you intend to monitor the Live Stream view continuously on a board or wall, in either mode, you can turn off the automatic timeout feature by adding the following parameter to the URL: ?session-idle-limitation-disabled
For example: https://<your-cloud>

To switch between modes:

  • Click the grid icon for grid mode or the tile icon for the device dashboard , respectively.

To search for specific executions:

  • In the Search field at the top right, enter any string included in the execution listing. For example, you can search by owner, platform, or device model.
    Live Stream updates dynamically as you type, showing only executions that match the entered string.


    In device dashboard mode, you can also use the filter panel to focus on executions of interest.
