Activate Central Monitoring for a region
To view a cluster's metrics, you must activate Central Monitoring for the region where the cluster is located. To do so, complete the steps in Turn on Central Monitoring for a region.
Important: Metric collection begins as soon as a new instance is provisioned, but initial metrics take 10 minutes to 1 hour to appear in the DCD or through the API. After that, you can poll for metrics at any time.
