How do I view CPU and memory usage for my Aurora DB cluster?
I want to view the CPU and memory usage for my Amazon Aurora DB cluster.
Resolution
Amazon Aurora automatically sends metric data for your DB instance to Amazon CloudWatch. View the metric data in the Amazon Relational Database Service (Amazon RDS) console. To view Aurora metrics in the CloudWatch console, see Overview of monitoring metrics in Amazon Aurora.
To view Enhanced Monitoring metrics, you must first turn on Enhanced Monitoring.
To view the available metrics for your DB cluster in the Amazon RDS console, complete the following steps:
- Open the Amazon RDS console.
- In the navigation pane, choose Databases.
- Select your DB instance.
- Choose the Monitoring tab.
- From the Monitoring menu, choose CloudWatch, Enhanced Monitoring, or OS process list.
In the operating system (OS) process list section of Enhanced Monitoring, review the OS processes and RDS processes. Use these metrics to determine whether an OS or RDS process caused an increase in CPU utilization. You can also use these metrics to monitor any CPU utilization increases that mysqld or Aurora cause. To see the division of CPU usage, review the metrics for cpuUtilization.

Title is misleading. this does NOT cover how to monitor memory. The metric does not seem to be available
Thank you for your comment. We'll review and update the Knowledge Center article as needed.
I am logged in as an admin but cannot turn on the enhanced monitoring without any feedback on why. Enhanced monitoring, OS process list and Performance Insight is just grayed out in the monitoring dropdown for my cluster.
Maybe add information for when this is the case.
