Subject: running ab command in cron

def get_web_performance(instance_url)
  web_performance = -111

  ab_command = "ab -n 1000 -c 5 -d -S -k http://" + instance_url +
"/dbcon/index.php:80/ "
  puts ab_command
  result = IO.popen(ab_command)
  puts result
  pipe = result.readlines
  pipe.each do |line|
    puts line
    if line =~ /^apr_socket_recv/
      #puts 111
      break
    end
    if line =~ /^Time per request:/
      #puts line
      stats = line.split
      #puts stats[3]
        web_performance = stats[3].to_i
      puts web_performance
      break
      end
    #puts line
  end
  return web_performance
end
if i run this code in shell. it works fine. when i run the ruby script
with cron i dont get any output of this line IO.popen(ab_command). is
there any thing i am missing?
