We had some inquiries about e.g. the total number of connections to a postgres cluster or the number of messages in all JMS queues. While this can be implemented as a metric in parent resource, it would be good to implement it in a generic way for groups of compatible resources. Those "auto-sum/min/max/avg" values would need to be available in the alert subsystem for the group.
