title: Where are the SNS/SMS logs? Cloudwatch empty
body: <p>Context: I use Amazon AWS, SNS service, to manually send SMS as a trial before I do any integration by code.</p>
  
  <p>I want to log the SMS reponses (the JSONs that appear here: <a href="http://docs.aws.amazon.com/sns/latest/dg/sms_stats_cloudwatch.html" rel="noreferrer">http://docs.aws.amazon.com/sns/latest/dg/sms_stats_cloudwatch.html</a> ) at some place.</p>
  
  <h2>Investigation done:</h2>
  
  <p>It seems I had to create an IAM role. I did it following the steps in the page, in the section "Viewing CloudWatch Logs". The role has been created. The policy for the role contains the following actions:</p>
  
  <pre><code>"Action": [
      "logs:CreateLogGroup",
      "logs:CreateLogStream",
      "logs:PutLogEvents",
      "logs:PutMetricFilter",
      "logs:PutRetentionPolicy"
  ],
  </code></pre>
  
  <p>I have set the "Default percentage of success to sample" to the <code>100%</code> so it should log all errors and successes...</p>
  
  <p>And now what? I have sent a couple of SMSs, I go to the Cloudwatch / Logs and all is empty.</p>
  
  <h2>Questions:</h2>
  
  <ul>
  <li>Where are the logs?</li>
  <li>Do I have to do anything else with the IAM to get that logged?</li>
  <li>Do I have to do anything in the Cloudwatch section?</li>
  <li>Where is it supposed I should be able to see the logs?</li>
  </ul>
  
  <p>I've spent 6+ hours with this and I want to think it is some silly point I'm missing. It can't be so complicated.</p>
  
  <p>The overall question is <strong>Where are the SNS/SMS logs and how do I activate them?</strong></p>
