Cloud Watch

Monitoring the aws services health dashboard:

You can use Amazon Cloud Watch Events to detect and react to changes in the status of AWS Personal Health Dashboard (AWS Health) events. Then, based on the rules that you create, Cloud Watch Events invokes one or more target actions when an event matches the values that you specify in a rule. Depending on the type of event, you can send notifications, capture event information, take corrective action, initiate events, or take other actions.

Create a Cloud Watch Events rule in each Region that you use. AWS Health events for a particular The region is published to Cloud Watch Events in that Region.

You can select the following types of targets when using CloudWatch Events as a part of your AWS Health workflow:

·         AWS Lambda functions

·         Kinesis streams

·         Amazon SQS queues

·         Built-in targets (CloudWatch alarm actions)

·         Amazon SNS topics

The following are some use cases:

·         Use a Lambda function to pass a notification to a Slack channel when an event occurs.

·         Send custom text or SMS notifications with Amazon SNS when an AWS Health event happens by using Lambda and CloudWatch Events.

Automating Actions for EC2  Instances:

You can automate actions in response to newly scheduled events for your EC2 instances. For example, you can create Cloud Watch Events rules for EC2 scheduled events generated by the AWS Health service. These rules can then trigger targets, such as AWS Systems Manager Automation documents, to automate actions.

For example, when an Amazon EC2 instance retirement event is scheduled for an EBS-backed EC2 instance, you can automate stop and start of the instance so that you don't have to perform these actions manually.
