With the growing business needs, the continuous expansion of your network is very prevalent. Be it a switch or a workstation, OpManager will automatically discover and monitor the devices added to your network in following ways, hence avoiding manual intervention.

OpManager will now run the discovery schedule in the specified time and the newly discovered devices will be automatically added to OpManager.
