RDS Storage Alert Expression Adjustment for Auto Grow Disk

Hi All,

I have an RDS instance that keeps triggering a warning alert on storage usage, even though the disk is configured to auto-grow. Currently, storage is just over 200 GiB and can grow up to a hard limit of 500 GiB.

Our Current expression mentioned is in the attached screenshot with the proposed expression?

Since the disk can auto-grow up to the 500 GiB hard limit, should we update the expression to the proposed?

Please confirm if this adjustment would be the correct approach?

Thanks,

storage

    Sounds reasonable, although I would suggest making it a new Complex Datapoint rather than modify the existing one. Collecting/showing both may help if situations like growth may not happen fast enough (there looks to be a 6+hr cool down on each growth) and you might still hit capacity before getting to 500GB.
