count = Hash.new{|h,k| h.update k => Hash.new{|h,k| h.update k => 0}}

case top_event[0].strip
   when /redo size:/i
     count[:redo][0] += 1
     count[:redo][1] += Float(top_event[1])

   when /logical reads:/i
     count[:read][0] += 1
     count[:read][1] += 1

...

require 'yaml'

y count


is one approach.

cheers.
