For AWS Aurora disk related (operations, latency, throughput) graphs are populated directly from CloudWatch. However, all data points are missing, because metrics are stored within RDSOSMetrics when enhanced monitoring is enabled.
This can be fetched directly from Prometheus, as rds_exporter fetches this (from /enhanced route).
