Namespace
Filters requested data that is specific to the nodes of a cluster.
NodeID will be either "Leader", "Shared", or "Compute-N"
where N is 0, 1, ... for the number of nodes in the cluster.
"Shared" means that the cluster has only one node, i.e. the
leader node and compute node are combined.
NodeIDAWS/Redshift
Filters requested data that is specific to the cluster. Metrics
that are specific to clusters include HealthStatus,
MaintenanceMode, and DatabaseConnections. In general
metrics in for this dimension (e.g. ReadIOPS) that are also
metrics of nodes represent an aggregate of the node metric
data.You should take care in interpreting these metrics
because they aggregate behavior of leader and compute
nodes.
ClusterIdentifier
