FreeStorageSpace calculating by percentage instead of bytes?

[michaelsew]

Hi - I noticed that the README mentioned that the FreeStorageSpace metric was in bytes (the cloudwatch default), but "could be changed to 10% database capacity".

This was in fact the functionality I was looking for -- monitoring FreeStorageSpace as a percentage, not raw bytes. I haven't seen the 10% database capacity anywhere in RDS documentation, nor does it seem to be in the alarms.tf. Is there in fact a way to monitor FreeStorageSpace as a percentage instead of bytes? if not, then there's a discrepancy in what the README advises.

This would be better indeed!
