Amazon CloudWatch Alarms - Introduction to DevOps on AWS

Amazon CloudWatch Alarms

You can set up alarms using Amazon CloudWatch alarms based on the metrics collected by Amazon CloudWatch metrics. The alarm can then send a notification to Amazon SNS topic, or initiate Auto Scaling actions. An alarm requires period (length of the time to evaluate a metric), evaluation period (number of the most recent data points), and datapoints to alarm (number of data points within the evaluation period).
