Period = 5 mins

Answer 1

The ReadProvisonedThroughputExceeded shows the

The number of GetRecords calls throttled

See here .

Meric is published per GetRecords call and the value is 0 if the call was not throttled or 1 if the call was throttled. So graphing the SampleCount will give you the number of GetRecords calls. Sum will give you the total number of throttled calls. The most useful stat here is probably the Average , which will give you the percentage of throttled calls.
