Monitoring Tools AWS provides various tools that you can use to monitor Amazon RDS. You can configure some of these tools to do the monitoring for you, while some of the tools require manual intervention. We recommend that you automate monitoring tasks as much as possible. Automated Monit ing Tools 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. For more information, see Using Amazon RDS Event Notification. * Database log files - View, download, or watch database log files using the Amazon RDS console or Amazon RDS AP! actions. You can also query some database log files that are loaded into database tables. For more information, see Amazon RDS Database Log Files. * Amazon RDS Enhanced Monitoring — Look at metrics in real time for the operating system. For more information, see Enhanced Monitoring. In addition, Amazon RDS integrates with Amazon CloudWatch for additional monitoring capabilities: * Amazon CloudWatch Metrics - Amazon RDS automatically sends metrics to CloudWatch every minute for each active database. You are not charged additionally for Amazon RDS metrics in CloudWatch. For more information, see Viewing DB Instance Metrics. * Amazon CloudWatch Alarms - You can watch a single Amazon RDS metric over a specific time period, and perform one or more actions based on the value of the metric relative to a threshold you set. For more information, see Monitoring with Amazon CloudWatch * Amazon CloudWatch Logs - Most DB engines enable you to monitor, store, and access your database log files in CloudWatch Logs. For more information, see Amazon CloudWatch Logs User Guide

The two services that can be used to automate the checks for database storage are CloudWatch and AWS Trusted Advisor.

CloudWatch is a monitoring service provided by AWS that can be used to monitor AWS resources like EC2 instances, RDS databases, ELB, and more. It provides detailed insights into resource utilization and performance metrics. You can use CloudWatch to monitor the storage of your databases and set up alarms to alert you when the storage limit is reached or exceeded. You can also create custom metrics and dashboards to track and analyze the database storage.

AWS Trusted Advisor is a service that provides guidance to optimize AWS resources. It provides recommendations in five categories: Cost Optimization, Performance, Security, Fault Tolerance, and Service Limits. AWS Trusted Advisor checks your AWS account and compares it to best practices, identifying areas where you can improve. In this case, it can provide recommendations to optimize the storage of your databases and prevent them from getting full.

Therefore, to automate checks for database storage, you can set up CloudWatch alarms to monitor the storage of your databases and configure AWS Trusted Advisor to provide recommendations to optimize the storage of your databases.
