   I am not sure if its better to make the metrics gathering more complicated here.  I do like to paradigm of an external system keeping track of intervals and metrics of intervals and functions only do very simple bookkeeping.  Even to keep the last 60 secs snapshot, why can't we offload this to an external system or even another function? Is it even useful for admins to see the last 60 secs of metrics? With only the last 60 secs of metrics, it seems to me, that only if you get lucky and get the metrics at the right time will you be only able to find problems.
