I use the Ruby AWS-SDK to create EC2 instances like this :

instance = ec2.instances.create({
  :image_id        => WORKER_AMI,
  :instance_type   => instance_type,
  :key_name        => 'cloud',
  :security_groups => 'worker',
  :user_data       => user_data_script,
  :count           => 1,

  :block_device_mappings => [
    {
     :device_name => "/dev/sda1",
     :ebs         => { :volume_size => 50, :delete_on_termination => true }
    }
  ]
})

When doing that, I get a 50 Gb root volume. But I also get a 360G ephemeral disk I don't need. In the AWS console, you can remove it in the wizard when you launch an instance. But how to do it via the SDK ?

When you monitor a process with Monit by its pid, like :

check process blop with pidfile /.../blop.pid
      start program = "..."
      stop  program = "..."

you get an alert when the pidfile is changed.

How do you disable this alert? For example, if you only want to know when the process fails to be restarted.
