The Job Status page shows you the execution status of Device Scripts.
In the Job Status table you will see:
The Script name
Its overall status - one of new, running, done, or failed
Date and time the script was started
Data and time the most recent update was received from any device
Actions - a trash can so you can delete a completed Job, or a square that lets you Cancel a Job which is still running.
The number of Devices in the Job
The number of "Failure" messages received
It is important to understand that on the average it takes 3 minutes for Job Status to update. So your script may actually complete and update the Status cells before the Job Status catches up. It should respond and update within 3 to 4 minutes.
