I'm missing metrics like [Billed] Volume Read IOPS (Count), [Billed] Volume Read IOPS (Count) in CloudWatch.
Although these metrics are visible in RDS -> CloudWatch. RDS CloudWatch metrics
Is it possible the find these metrics in CloudWatch so I can create alarm for them?
Update: it turns out that these metrics are available as:
VolumeBytesUsed -> [Billed] Volume bytes used
VolumeReadIOPs -> [Billed] Volume read IOPs
VolumeWriteIOPs -> [Billed] Volume write IOPs
These metrics are available as VolumeBytesUsed, VolumeReadIOPs, VolumeWriteIOPs (note the "Volume" prefix).
I will take the opportunity to point out that "IOPS" is a misnomer for these metrics; they are really "IOP5M" or "IOs per 5 minutes." (Thanks, AWS.)
Therefore there is a ~300x difference between ReadIOPs and VolumeReadIOPs.
There is not a linear relationship between WriteIOPs and VolumeWriteIOPs because the latter is boxcared into 8KB(?) chunks and the former is not.
Very confusing, but I hope that helps.
