Database administrators, application teams, and architects are concerned about addressing performance issues before they affect end-user experience or cause outages. Amazon Relational Database Service (Amazon RDS) offers various monitoring tools to help achieve this goal, such as Enhanced Monitoring and Performance Insights. Enhanced Monitoring provides detailed operating system metrics that can be used to create alarms and perform calculations.
In a recent post, the process of importing multiple Enhanced Monitoring metrics into Amazon CloudWatch was detailed. This enables users to view metrics for more than an hour, host multiple metrics on the same chart, adjust the granularity of data points, compare metrics, and perform mathematical calculations. Performance Insights offers a custom dashboard for correlating Enhanced Monitoring metrics with other metrics, although additional costs may apply for using this feature.
By using an AWS CloudFormation template, users can automate the import of multiple Enhanced Monitoring metrics from an RDS instance to CloudWatch. This process creates a CloudWatch dashboard with metrics grouped by category for easy viewing and comparative analysis. The CloudWatch dashboard displays all the enhanced monitoring metrics specified in the CloudFormation stack parameters.
To implement this solution, users need to set up an RDS instance for MySQL, enable enhanced monitoring, and deploy the CloudFormation stack. It is important to note that there are limitations to the number of metrics that can be created per engine, and that custom CloudWatch dashboards and metric filters incur additional costs. There are also strict limits on the number of metric filters that can be created per AWS Region.
Once the metrics are available in CloudWatch, users can create alarms to monitor them and take advantage of the full power of CloudWatch for tracking performance. The authors of the post are experts in database management and cloud support at Amazon Web Services, providing technical assistance and best practices for database operations and optimization.
In summary, the process outlined in the post allows users to efficiently monitor and analyze performance metrics for RDS instances using CloudWatch, helping to proactively address any issues that may arise. Cleaning up resources after use is recommended to avoid unnecessary costs. If users have any questions or comments, they are encouraged to leave them in the comments section.
