Automatic Monitoring tools are divided into three components as mentioned below:
a) System Status Check.
b) Instance Status Check.
c) Amazon CloudWatch.

A system check is a tool that can detect the problem that may harm your instances and the System Status Check tool is preprogrammed to check the reachability of the AWS system and ensure that the AWS system functioning. If you get System Status Check fails, you can resolve the detected issue by yourself (for example, by stopping and restarting or terminating and replacing an instance) or choose to wait for AWS to fix it.

For the resolution, you can reboot the instance or by modifying your operating system or use other instinctive ways to resolve the issue.

Amazon CloudWatch
Amazon CloudWatch is a component of Amazon Web Services that provides real-time monitoring of AWS resources or applications that are currently active on the AWS cloud infrastructure.

Resources Monitored by Amazon CloudWatch:

  1. Amazon EC2 Machine
  2. Amazon RDS
  3. Amazon Elastic Load Balancer
  4. Amazon S3

CloudWatch Alarms is an alarm that can be used to automatically initiate action on your behalf. It watches a single metric over a specified time period, and perform one or more specified action.

CloudWatch Events deliver a near real-time flow of system events that report changes in Amazon Web Services (AWS) resources.
