title: Sending an SNS Notification when Alarm state changes to OK
body: <p>I have monitored the status of VPN tunnels in my account.I have created CloudWatch alarms and configured SNS notifications when they are down.
  At the moment, that is working fine. Now, I have got another requirement saying I have to send alarm whenever the state changes to OK.</p>
  
  <p>This is the image of the alarm configuration :</p>
  
  <p><a href="https://i.stack.imgur.com/z3EOc.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/z3EOc.jpg" alt="enter image description here"></a></p>
  
  <p>There, in the snapshot, it says :</p>
  
  <p><strong>Whenever this alarm : STATE is ALARM</strong></p>
  
  <p>I would change that to :</p>
  
  <p><strong>Whenever this alarm : STATE is OK</strong></p>
  
  <p>But, by doing that, will the Cloud Watch send me notifications every 5 minutes until the state is in OK? 
  I have this doubt because it is written STATE is OK instead of STATE changes to OK.
  Please let me know.</p>
