If the DUT is rebooted during testing, it looks like the dut_monitor.py script on DUT would not start running again. Is there a way to restart it after rebooting?

"DUTMonitorClient" class takes care of it. It will automatically restart monitoring script when device become accessible.

A general question on this DUT monitor, can we also plan to have CRM monitoring here. For eg, if any alarms/warnings are raised for CRM resources. May be as a phase 2 commit?
