Configure an Alert Based on Logging Content

In this lab, we'll walk through the process to filter over existing logging data inside of CloudWatch Logs. We'll start by creating a SNS topic without a subscription, then filter our CloudWatch Logs data to create a metric filter. After creating a metric filter and defining our metric, we will configure an alarm to send notifications to our created SNS topic.
