unit property
When you are using a Put operation, this defines what unit you
want to use when storing the metric.
In a Get operation, if you omit Unit then all data
that was collected with any unit is returned, along with the corresponding
units that were specified when the data was reported to CloudWatch. If you
specify a unit, the operation returns only data that was collected with that
unit specified. If you specify a unit that does not match the data
collected, the results of the operation are null. CloudWatch does not
perform unit conversions.
