On the X4 what you are looking for is the event log. You can access this through the Web GUI or through Device Cloud
To access the event log on Device Cloud go to the Command Line Interface and type in >display log:
Also, below the Command Line Interface is the Connection History. For other useful commands available through the Command Line Interface, see the Command Reference: Digi Connect Family at this link http://www.digi.com/support/productdetail?pid=3604&type=documentation.
Note: Not all CLI commands are available through the Device Cloud as they take too long to implement and will time out before completion. The “display log” command works as verified above.
