You can get the cluster devices with all devices inside these cluster by using a Device42 Object Query Language (DOQL).
The query is:
m.name as Cluster_Device,
string_agg(d.name, '; ') as "Devices in Cluster"
from view_device_v1 m join view_devices_in_cluster_v1 c on c.parent_device_fk = m.device_pk
join view_device_v1 d on d.device_pk = c.child_device_fk
m.type like '%cluster%'
To run the query please use the following URL:
Replacing the D42_IP with your appliance IP or DNS
And use "," as column separator
The output will be a CSV file which will be downloaded on your computer.
