In the Actions column, click the 
icon to open the
Execution History page which is filtered on the selected
task.
For example here, you can see that the second execution ended with an error while
the other executions succeeded, and that two executions are not started yet.
From the Actions column of the Execution
History page, you can either execute the task in its current status,
open the Error Recovery Management page where you can recover
a Job which execution failed, or show the statistic view of the corresponding
execution.
Alternatively, to open a graphical view of this Job history, click
Timeline in the
Talend Administration Center menu to open the corresponding page.
