Monitor Aurora with CloudWatch metrics, alarms, and SNS

Andreas Wittig – 23 Jul 2018

Besides traditional database engines like PostgreSQL, MySQL, MariaDB, Oracle, and Microsoft SQL Server, AWS offers a cloud-optimized database engine as well: Amazon Aurora. The main benefits of Aurora are performance, reliability, and scalability. Because Aurora is a fully managed service, there are only a few things you have to monitor.

CloudWatch metrics

Each cluster sends metrics to CloudWatch that we can monitor with CloudWatch alarms. We recommend creating alarms for the following metrics:

  • CPUUtilization: The percentage of CPU used by an Aurora DB instance.
  • CPUCreditBalance: The number of CPU credits left (only applies to db.t* instance types).
  • FreeableMemory: The amount of available random access memory in MB.

Events via SNS

Besides metrics, RDS sends out events if the state of the database instance has changed. E.g., because of a failover.

We recommend subscribing to events of the following categories:

  • failover
  • failure
  • low storage
  • maintenance
  • notification
  • recovery
