Running tasks

This topic describes the Running tasks section and the information it provides.

 

Board is capable of executing various multiple tasks simultaneously. In this page, you can monitor and stop tasks that are currently being executed in real-time by the Board engine of a Platform. Tasks displayed in this page include the following:

• Execution of a Dataflow Procedure step
• Execution of a Layout
• Application of a Selection
• Execution of a Data reader
• Retrieval of items of a Data model, such as the list of Entities, Cubes, Relationships etc.
• Data dictionary
• Nexel calculation
• All other Procedure steps that are executed by the Board engine (i.e. Extract steps, Backup database, Save pending changes to disk etc.)

All the tasks mentioned above are single tasks that are typically contained in a Procedure or a Screen etc. Therefore, this page displays the name of the individual task being executed rather than the name of the location from which the task originates, such as the name of a Procedure, Capsule, or Screen.

 

To access the Running tasks section, access the System Administration area of the desired Platform and click on the Running tasks tile. You will be taken to the Running tasks page.

In the Running tasks page, you can see all currently running tasks on the Board engine of your Platform and their information: the table contains the following information:

• Name. This column displays the name of each running task
• Status. This column displays information about the status of each running task. In some cases, the column may display the exact task it is processing, such as the type of action of a Dataflow Procedure step and the name of the Cube on which the action is being performed
• Username. This column displays the username of the user that has started the execution of each task
• Elapsed time. This column displays the time that has passed since the start of the execution of each running task, displayed in the following format: HH:MM:SS
• Progress. This column displays a progress bar that shows the progression percentage of each running task
• Break. This column displays a "STOP" button for each running task that you can click to stop the execution of that task

  In the case of a Procedure with multiple steps, the "STOP" button stops only the execution of the current single step.

  In the case of a task that is a write action, the "STOP" button will only stop it if it has not yet written any data in the target structure, or if the writing of data has reached a coherent checkpoint (i.e. a Dataflow action may be stopped during the Tuple pre-calculations, but not during the actual writing of the calculation result in the target Cube).

 

The page is automatically refreshed once every second. This is also why sometimes you may not see tasks that are executed and terminated in less than a second.

The page displays no data if there are no running tasks.
