From: "Dr. David Alan Gilbert" <dgilb...@redhat.com> Hi, This is an attempt at a generic rolling statistics utility to allow data (e.g. bandwidth usage, times etc) to be collected easily. They hold some basic values (min/max/mean/weighted mean) and the last 'n' raw values. I'd like to use this maybe in fault-tolerance code.
This is a first cut, and I think I probably need to rework it as a qapi type somehow, but I'm interested in thoughts.
