We will create a monthly savings plan coverage budget which will notify if the coverage of Savings Plan for EC2 is below the specified amount.
You should not set an arbitrary limit to alarm on (i.e. alarm if coverage is less than 80%) instead select your current level of coverage - so if coverage reduces, you can act and increase coverage if required.
