 - Fix fields not being parsed correctly in postgresql/database {issue}25301[25301] {pull}37720[37720]
 - rabbitmq/queue - Change the mapping type of `rabbitmq.queue.consumers.utilisation.pct` to `scaled_float` from `long` because the values fall within the range of `[0.0, 1.0]`. Previously, conversion to integer resulted in reporting either `0` or `1`.
 - Add AWS OwningAccount support for cross account monitoring {issue}40570[40570] {pull}40691[40691]
+- Add missing ECS Cloud fields in GCP `metrics` metricset when using `exclude_labels: true` {issue}40437[40437] {pull}40467[40467]
