Datadog integrates with AWS CloudWatch to gather RDS metrics and provides a comprehensive view of database health and performance by correlating native MySQL metrics with RDS metrics, allowing for the identification of recent and long-term trends and performance problems. To connect MySQL RDS to Datadog, users need to configure the AWS CloudWatch integration and set up role delegation in AWS IAM, create a new role for Datadog, and attach a policy that grants read-only access to AWS services. The Agent integrates seamlessly with MySQL to gather key performance metrics, which are reported at a higher resolution than basic CloudWatch metrics. Users can enable enhanced monitoring for RDS instances running MySQL, which includes more than 50 new CPU, memory, file system, and disk I/O metrics that can be collected on a per-instance basis as frequently as once per second. Once integrated with Datadog, users can access a comprehensive dashboard called “Amazon - RDS (MySQL)” that gathers key metrics around query throughput and performance, resource utilization, database connections, and replication status.
