ruby -rcolorize -rnet/http -e '
def check()
  s_time = Time.now()
  res = Net::HTTP.get_response(URI( "https://example.com/"))
ensure 
  e_time = Time.now()
  code = defined?(res.code) ? res.code : "5xx"
  return [e_time - s_time, code]
end
while true do
  sleep 1
  result = check()
  time = result[0].round(2)
  code = result[1]
  if code == "200"
    time_s = "#{time},"
    if time > 0.9
      printf time_s.red
    elsif time > 0.3
      printf time_s.yellow
    else
      printf time_s
