How to check to which hub a robot currently is reporting?

If we have multiple secondary hubs and one of hubs is down, robot(s) under the problematic hub seeks and reports to next available hub.

How we know to which hub the robot(s) currently is reporting?

Run the following query against UIM database to get the hub that the robot(s) is currently reporting to.

select check_time, hub, robot from CM_NIMBUS_ROBOT where robot like '%<robot_name>%';
