 ## Enhanced Metrics
 
-Introducing Enhanced Metrics for Azure Database for PostgreSQL Flexible Server to enable more fine grained monitoring and alerting on databases. You can configure alerts on the metrics. In addition, some of these new Metrics also now also include ‘Dimension’ that will allow to split and filter the metrics data by using the allowed dimension such as Database Name, State etc.
