 * For each timeseries, only the most recent data point is exported.
 * Stackdriver `GAUGE` metric kinds are reported as Prometheus `Gauge` metrics; Stackdriver `DELTA` and `CUMULATIVE` metric kinds are reported as Prometheus `Counter` metrics.
-* Only `BOOL`, `INT64` and `DOUBLE` metric types are supported, other types (`STRING`, `DISTRIBUTION` and `MONEY`) are discarded.
