I don't think there is a way to search device ID in the Web Console.
Try this:
Log on to putty with root & run this command, copy this command & paste in putty:
psql -q -A -F ";" -U ovidrw -d oviddb -c "select cd.device_id AS \"DEVICE ID\", cm.hostname AS \"MACHINE HOSTNAME\" from client_device as cd left join client_machine_client_device as cmcd on (cd.uuid=cmcd.client_device_uuid) left join client_machine as cm on (cmcd.client_machine_uuid=cm.uuid)" >Export_ManagedClients.csv
Log on WinSCP & move the file named Export_ManagedClients.csv to your PC.
Sort this file in excel & remove duplicates.
You'll have 2 columns, one with device IDs & the other with Computer hostnmes.
Does this help?
