[Qemu-devel] [PATCH 0/2] RFC: Rolling statistics

[Dr. David Alan Gilbert (git)]

From: "Dr. David Alan Gilbert" <address@hidden>

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.

Dave
