title: AWS - find all instances that are running but nobody is connected to them
body: <p><strong>Hello!</strong></p>
  <p>I need to find all instances that are currently running, but nobody connected to them via port 22 or 3389 for the past 2 weeks.</p>
  <p>I figured I could use <em>VPC Flowlogs</em> and <em>Athena query</em> to create a list of network interfaces and then eliminate manually all instances with those network interfaces that are not on the list.
  It's a tedious work so I am looking for more efficient way to get needed information.</p>
  <p>Do you have any ideas how to approach this problem differently?</p>
