Emergency script to kill out of control Rails processes. Thanks to /dev/urandom :(

hog_killer.rb

grep_output = `ps aux | grep Rails`

kill_list = []
any_rails = grep_output.scan(/^www-480\s+(\d+)\s+(\d+.\d+).*Rails/)
any_rails.each do |process|
  pid = process[0]
  cpu = process[1]

  if cpu.to_f > 95.0
    kill_list << process
  end

end

if kill_list.length > 0 
  kill_list.each do |process|
    pid = process[0]
    cpu = process[1]
    `kill #{process[0]}`
    `echo "#{pid} #{cpu}% killed - #{Time.now}" >> /home/hog_kills.log`
  end
  `/sbin/service httpd restart`
end
