https://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/CHAP_Monitoring.htmlThe two AWS services that can accomplish the requirements of monitoring and sending notifications for databases hosted on Amazon RDS are Amazon CloudWatch and Amazon Simple Notification Service (SNS).
Amazon CloudWatch is a monitoring service that provides a comprehensive view of resources and applications running on AWS. CloudWatch can monitor RDS instances and capture a wide range of performance metrics, such as CPU utilization, memory usage, network traffic, and disk I/O. These metrics can be used to set alarms that trigger notifications to IT admin staff when predefined thresholds are breached.
To set up CloudWatch monitoring for an RDS instance, you can use the CloudWatch console or AWS CLI. You can also use CloudWatch Logs to capture and analyze log data generated by RDS instances.
Amazon Simple Notification Service (SNS) is a notification service that can send messages or alerts to various endpoints, such as email addresses, SMS text messages, and mobile push notifications. You can use SNS to set up alerts and notifications based on CloudWatch alarms that trigger when RDS performance metrics exceed predefined thresholds.
To set up SNS notifications for CloudWatch alarms, you can use the SNS console or AWS CLI. You can specify one or more endpoints that should receive the notifications, such as email addresses or phone numbers. You can also customize the notification messages and formats.
In summary, using Amazon CloudWatch and Amazon Simple Notification Service (SNS) together can provide comprehensive monitoring and notification capabilities for RDS databases hosted on AWS. CloudWatch captures RDS performance metrics, while SNS delivers notifications based on predefined thresholds.
