I am expecting prestodb support too, hop it's merged soon.

Encountered this problem too, and the metric parameters are like below: ``` MetricData.member.6.MetricName=UserRecordsReceived MetricData.member.6.Dimensions.member.1.Name=StreamName MetricData.member.6.Dimensions.member.1.Value= MetricData.member.6.Timestamp=2018-07-29T19%3A49%3A12Z MetricData.member.6.StatisticValues.SampleCount=0 MetricData.member.6.StatisticValues.Sum=0 MetricData.member.6.StatisticValues.Minimum=1.79769e%2B308 MetricData.member.6.StatisticValues.Maximum=-1.79769e%2B308 ```
