Hacky patch to unicorn to log process ram use after each request

gistfile1.rb

class Unicorn::HttpServer
 alias process_client_orig process_client
 undef_method :process_client
 def process_client(client)
  process_client_orig(client)
  rss = `ps -o rss= -p #{Process.pid}`.chomp.to_i / 1024
  puts "Unicorn #{Process.pid}, #{request.env['REQUEST_METHOD']} #{request.env['REQUEST_PATH']} using #{rss}M"
 end
end
