Hi Martin,
I'm using unicast reporting in hierarchies, so the largest cluster info held by a gmond doesn't exceed 2TB. The gmetads performing aggregation display this problem. After looking at the code, it seems that gmetad indeed stores the aggregated information in an unsigned integer (32 bit on an x86_64 Linux).
