title: Monitoring Memory Usage for multiple EC2 instances
body: <p>I am able to monitor a Windows instance's memory usage using custom metrics in CloudWatch.</p>
  
  <p>I have followed the following blog to achieve that :</p>
  
  <p><a href="http://blog.krishnachaitanya.ch/2016/03/monitor-ec2-memory-usage-using-aws.html" rel="nofollow noreferrer">http://blog.krishnachaitanya.ch/2016/03/monitor-ec2-memory-usage-using-aws.html</a></p>
  
  <p>Using that, I am able to monitor only one instance. I am now doing the process in every instance launched.</p>
  
  <p>Can I do it at once for all instances instead of changing .json file and enabling cloud watch integration in every instance?</p>
