RedShift Filter Name
By default, this test reports metrics only for each cluster in each AWS region on the cloud. This is why, this flag is set to ClusterIdentifier, by default. If needed, you can configure the test to additionally report metrics for every node in every cluster. For node-level metrics, select the NodeIdentifer option from this drop-down. Upon selection, you will be able to view metrics both at the cluster-level and the node-level.
