Another possibility is to use the probe: sql_response to execute each hour (or any other freq):
---
SELECT nm.robot,cs.create_time,nm.check_time, nm.hub from CM_COMPUTER_SYSTEM cs INNER JOIN CM_NIMBUS_ROBOT nm on nm.robot=cs.name where create_time >= DATEADD(hh, -1, GETDATE())
---
This could generate someting like:
new_robot_discovered/bgbulab53/CA_UIM: name: bgbulab54
