title: AWS CloudWatch Events delay in CloudTrail log
body: <p>I want to monitor the change in security group of an EC2 instance using CloudWatch Events. So, used <code>API call via CloudTrail</code> as the event type.</p>
  
  <p>Typically, CloudTrail delivers an event within 15 minutes of the API call which would hinder the near real-time Security group change monitor?</p>
  
  <p>How can I improve this?</p>
