Note that I've been asked about exactly this a couple of days ago.
If our metrics were complex data, we could do really wild things like having a metric that
would describe a topology of a cluster, etc.

This was originally meant for data that is not a simple value or calltime,
but
rather tabular data like min/avg/max/count for method calls or similar.
The hibernate statistics that we now return in an operation could have been
such a complex metric. But we never implemented it and I guess that was
mostly because this kind of data does not easily transform into a relational
model.
Now with C* we could revisit the idea if anyone is missing it ;->
