Remove All Monitored Devices from DPOD

Navigate to [Manage → Topology → Gateways → Delete Gateway] and delete all monitored devices. Make sure to check the option "Delete Syslog logs targets from device" in the confirmation window.

For a complete removal of all changes made by DPOD to the monitored devices, see Gateway Changes Performed by DPOD.

Reset or Delete the Server

Since the appliance includes the operating system, the server needs to be reset (e.g. by formatting the disks) or simply deleted if it is running as a virtual machine.
