CloudWatch Events can detect important changes, such as an EC2 instance transitioning to the stopped state, an S3 object being deleted, or a Lambda function execution status changing. You can define rules in CloudWatch Events to trigger target actions when specified events or state changes occur. These target actions can include invoking Lambda functions, running Amazon ECS tasks, or sending notifications through Amazon SNS. Event Monitoring can help improve your operational efficiency by automating responses to critical changes in your environment or by notifying the appropriate personnel when specific events occur.
Full Guide: AWS CloudWatch Event Monitoring for AWS Solution Architect
What is Event Monitoring? Event Monitoring is a feature in AWS CloudWatch that allows you to track and respond to changes in your AWS resources. It gives visibility into your application regarding application performance and operational health.
Why is it Important? Event Monitoring is crucial as it helps you to react quickly to operational changes and maintain system reliability, availability, and performance. If there are any issues such as significant latency or an application failure, an event can be triggered indicating the issue.
How it Works? CloudWatch Event Monitoring works by responding to state changes to your AWS resources. When any AWS resource changes state, an event is generated. You can create rules that match selected events in the event stream and route them to targets to take action.
Exam Tips: Answering Questions on Event Monitoring 1. Emphasize on what Event Monitoring is and its importance in maintaining the overall system's health2. Be aware of how it works, especially about state changes and the event stream3. Understand the rules for event matching and routing to the appropriate targets4. Be prepared to answer scenario-based questions focused on problem solving and quick response to operational changes.
Useful Tips 1. When it comes to Event Monitoring, AWS CloudWatch tracks and responds to the events, not just monitoring2. Actions are taken based on rules you define3. Event stream represents a feed of events emitted by AWS resources.
