Extract detailed Redshift utilization metrics #417

Closed geoffxy closed 9 months ago

Right now we use an aggregated CPU utilization metric to compute system load (on Redshift). This aggregated value is not enough to scale Redshift because of the different compute node roles in the cluster. We should leverage the NodeID dimension to get more detailed metrics.
