`#### Note about throttle
Throttle can be set globally as
gcloud-monitor opt or on each individual "metric" as a factory opt. This option throttles metric reports to the interval specified in ms.Cumulative time series metrics batching can be grouped by passing
opt.groupBy function. For example, if you want to batch cumulative metric data grouped by label name: groupBy: (timeSeriesItem) => (timeSeriesItem.metric.labels && timeSeriesItem.metric.labels.name)`
