Managing Report-Running Tasks
This topic describes how you can view and manage report-running tasks on Logi Report Server.
You can perform the following fundamental report-running tasks on Server: quickly view a report result (Run), view a report result using selected options and parameters (Advanced Run), and schedule a report to run unattended at a specific time or periodically (Schedule).
You can view the status of these report-running tasks, such as scheduled tasks that are waiting to be performed by Logi Report Server, the tasks that are currently being performed, and the tasks that have already been performed.
This topic contains the following sections:
- Accessing the Task Information Tables
- Managing Report-Running Tasks in the Task Tables
- Task-Level Timeout for Advanced Run and Schedule Tasks
Accessing the Task Information Tables
Server collects task information and manages it in a set of tables.
- Server displays the tasks that you scheduled in the following tables:
- Scheduled table
Status information of scheduled tasks that are waiting to perform, such as task ID, whether the task is enabled, previous running time, and next running time. - Running table
Status information of tasks that are currently being performed, such as task ID, time when the task was started, and engine status. - Completed table
Status information of tasks that have already been performed, such as task ID, time when the task was completed, whether the task performed successfully, result files, and error messages.
- Scheduled table
- Server displays the tasks that you performed using Run, Advanced Run, or Background Run in the Background Tasks table.
- Background Tasks table
Status information of the tasks that you Run, Advanced Run, or Background Run reports, such as report path and name, catalog path and name, running format, time when the task was started/completed, time elapsed since the task was performed, and the status of the task.
- Background Tasks table
To access a specific table, in the Server Console select My Tasks on the system toolbar, then select the corresponding tab. You can also use URL commands to directly open a task table.
The following introduces the task tables.
The Scheduled table consists of the following columns:
| Column | Description |

Server provides a background running system, which shows the status information of tasks that you submitted using the Run, Advanced Run, or Background Run mode.
Server clears the records that it saved in the background running system under the following conditions:
- Logi Report Server restarts.
- The maximum time limit specified for the report result life is reached. By default, it is 86400 seconds (24 hours).
- The maximum time limit specified for the interval between a user logout and login is reached. By default, it is 300 seconds.
- If the number of records exceeds the number specified for the background task list (by default it is 100 records), Server only retains the latest 100 records.
The Background Tasks table consists of the following columns:
| Column | Description |
|---|---|
| Report Tabs | The names of the report tabs in the report that this task included. |
| Result | The result in the format in which the report ran. You can select the format link to open the report result. For a Page Report result, Server removes the task automatically once you opened the result. |
| Report | The path and name of the report that the report tabs belong to. |

Tips:
- You can customize the columns shown in the tables as follows: switch to the table, select Preferences on the task bar of the My Tasks page (for the Scheduled table, select Tools > Preferences on the task bar), select the corresponding items in the Preferences dialog box, then select OK to apply the settings.
- You can sort the records in each table in the ascending or descending order by any column title. To do this, select on the underlined column title on which you want to sort the records. Server displays a sort icon right after the title, showing the sort direction.
- You can use the Search box above each of the tables to search for the desired tasks in this table. Type the text of the schedule names or report tabs in the box and Server lists the tasks that contain the matched text.

Task-Level Timeout for Advanced Run and Schedule Tasks
Server introduces the task-level timeout mechanism to avoid the never-finished running tasks consuming server resources and thus decreasing the server performance. With the mechanism, you can specify a time duration for a task, and ask Server to cancel the task or to notify you or someone else of the task status via e-mail if the task has not yet finished running when the task duration is up. To do this:
- Do either of the following to enable the task-level timeout mechanism.
- In the server.properties file in
<install_root>\bin, set the task.duration.enable property to true. - In the Server Console, point to Administration on the system toolbar, and then select Configuration > Advanced from the drop-down menu. Server displays the Advanced page. Select the Enable Task Duration option.
- In the server.properties file in
- By default, Server checks task duration every 30 seconds. You can reset the period value by either of the following:
- In the server.properties file, set the task.duration.check_cycle property.
- In the Administration > Configuration > Advanced page, set the Status Refresh Interval option.
The period value must be an integer greater than 0. Since task duration check frequency affects server performance, you should set the value according to your system environment.
- Use the Duration tab in the Advanced Run or Schedule dialog box to specify task duration.
- In the Timeout text box, specify the time limit for when the task can run before notifying of the timeout or canceling the task.
- If you want to notify someone of the task status if the task has not yet finished running when the task duration is up, select Notify by e-mail after the specified time and specify the email address in the Mail To text box.
- If you want Server to cancel the task when the task duration is up but the task has not finished yet, select Cancel the task after the specified time.
- Submit the task.
Then, when the specified task duration is up but the task has not finished running,
- For an Advanced Run task
- If you have specified to have server cancel the task when the task duration is up, the task will be cancelled automatically, however, a record for the task will be still remained in the Background Tasks table of the My Tasks page, shown with a sign of cancellation.
- In the Duration tab, if you have not selected the option Cancel the task after the specified time, the task will be switched to run in background mode when the task duration is up, in which case, you can choose to cancel the task manually. To do this, in the Background Tasks table,
- Select the task row and click Edit > Delete on the task bar of the My Tasks page.
- Select the task row, right-click in the row and select Delete from the shortcut menu.
- Put the mouse pointer over the task row and select the Delete button
on the floating toolbar.
- For a Schedule task
- If you have specified to have server cancel the task when the task duration is up, Server cancels the task automatically, and adds a task completed record in the Completed table of the My Tasks page, with the Is Successful status being No.
- In the Duration tab, if you have not selected the option Cancel the task after the specified time, Server still lists the task in the Running table of the My Tasks page when the task duration is up. Then, if you want to cancel the task manually, do one of the following in the Running table,
- Select the task row and select Stop on the task bar of the My Tasks page.
- Select the task row, right-click in the task row, and select Stop from the shortcut menu.
- Put the mouse pointer over the task row and select the Stop button
on the floating toolbar.
- Server may not cancel a task right after the specified task duration is up due to check frequency.
- You should set the task duration to about five times of the required time for finishing running the task.
