There are many methods to check the used storage size in RDS. One of the simplest methods to check RDS’s used storage size is as follows:
Go to the AWS Console
Go to Databases > Relational Database Service (RDS)
Click on your DB instance name
Go to the Configurations Tab and under the Storage section you can see the total storage allocated
Now Go to the Monitoring Tab
Here you can see how much Free Storage Space you have
Total Storage space and Free Storage Space can help you deduce how much is the used storage size
If you are using Anodot’s services for your RDS management, all such metrics are always readily available to you at your fingertips at all types on your Anodot dashboard.
