I have it working however it's funky depending on Cloudwatch's metrics.
It only works for when the measured metric from Cloudwatch is numerically greater than the warning or critical threshold metrics. So it works great for CPU since if it measures 80 from RDS Cloudwatch that meants it's at 80% use. However when measuring RDS FreeStorageSpace it won't work the same. FreeStorageSpace measures the empty space in RDS. This script won't work when you want to alert warning at 20GB free and then critical at 10GB free it will never trigger.
What would be ideal is if CloudWatch could measure UsedStorageSpace as well as FreeStorageSpace. Is there any way this script can measure the inverse?
If I could alert warning when RDS is 80% USED and 90% USED I think this script would be even more powerful.
