You can use the following automated monitoring tools to watch Amazon RDS and report when something is wrong:
Amazon RDS Events – Subscribe to Amazon RDS events to be notified when changes occur with a DB instance, DB snapshot, DB parameter group, or DB security group. Database log files – View, download, or watch database log files using the Amazon RDS console or Amazon RDS API operations. You can also query some database log files that are loaded into database tables. Amazon RDS Enhanced Monitoring — Look at metrics in real time for the operating system. Amazon RDS Performance Insights — Assess the load on your database and determine when and where to act. Amazon RDS Recommendations — Look at automated recommendations for database resources, such as DB instances, read replicas, and DB parameter groups. In addition, Amazon RDS integrates with Amazon CloudWatch, Amazon EventBridge, and AWS CloudTrail for additional monitoring capabilities:
Amazon CloudWatch Metrics – Amazon RDS automatically sends metrics to CloudWatch every minute for each active database. You don’t get additional charges for Amazon RDS metrics in CloudWatch. Amazon CloudWatch Alarms – You can watch a single Amazon RDS metric over a specific time period. You can then perform one or more actions based on the value of the metric relative to a threshold that you set. Amazon CloudWatch Logs – Most DB engines enable you to monitor, store, and access your database log files in CloudWatch Logs. Amazon CloudWatch Events and Amazon EventBridge – You can automate AWS services and respond to system events such as application availability issues or resource changes. Events from AWS services are delivered to CloudWatch Events and EventBridge nearly in real time. You can write simple rules to indicate which events interest you and what automated actions to take when an event matches a rule AWS CloudTrail – You can view a record of actions taken by a user, role, or an AWS service in Amazon RDS. CloudTrail captures all API calls for Amazon RDS as events. These captures include calls from the Amazon RDS console and from code calls to the Amazon RDS API operations. If you create a trail, you can enable continuous delivery of CloudTrail events to an Amazon S3 bucket, including events for Amazon RDS. If you don’t configure a trail, you can still view the most recent events in the CloudTrail console in Event history.
