Creating a Service and adding a Dynamic search Global Collection (GC) as the resource for the service:
However, when this GC is chosen as the Resources for the Service, it doesn't dynamically update as the GC updates, the service continues to contain previous devices that are now online and no longer in maintenance.
DX NetOps Spectrum Release : 20.2 or later
Monitoring of dynamic GC is supported. The issue here is that individual device models have been manually added to the Service's Resources. Remove any manually added models from the Resources.
Then, whenever the new resource is added/deleted from the GC, you should see the correct resources (devices) under the Resource tab of that service/resource monitor automatically.
It should update when the GC members change in the above view.
