Hi,
In the client you can select a task, right click on it and select: 
Task log.
You can see the log here of the task.
There is an option to show the StandardOutput, but when I double clickon it I see the output of a different task. 
It looks like it gives the output of the 1st task in the job.Regards,
Erik
