In this Lab, you will explore CloudWatch, a monitoring service provided by AWS. CloudWatch makes it possible to monitor nearly anything inside or outside AWS. Common usage is to monitor EC2 instances for CPU and memory utilization, ephemeral or EBS volume disk usage and throughput, as well as network statistics. CloudWatch also enables you to configure alarms, so that when thresholds are violated for specific metrics a notification and/or action is automatically triggered.
Although this is a beginner level Lab, you should be familiar with:
