title: Amazon CloudWatch: How to find ARN of CloudWatch Log group
body: <p>I configure Custom Access Logging for Amazon API Gateway and I need to specify CloudWatch Group name, but when I put these just name of log group in format like "API-Gateway-Execution-Logs_3j5w5m7kv9/stage-name" I get such error:</p>
  
  <blockquote>
    <p>Invalid ARN specified in the request. ARNs must start with 'arn:':
    API-Gateway-Execution-Logs_3j5w5m7kv9/stage-name</p>
  </blockquote>
  
  <p>When I open page of this log group in CloudWatch I just see the same name there and don't see ARN value. How can I find it?</p>
